[issue46466] help function reads comments
New submission from David Mc Dougall :
My inline comment ('#') got picked up by the help command.
Write the following code to a file (I named it "reproducer.py"):
"""
class Foo:
# Hello docstring, I'm a '#' comment!
def bar(self):
pass
assert Foo.bar.__doc__ is None
help(Foo.bar)
"""
The bug only happens when the file is executed.
$ python3 reproducer.py
Help on function bar in module __main__:
bar(self)
# Hello docstring, I'm a '#' comment!
Evaluating it at the interactive prompt does not reproduce the bug.
$ cat reproducer.py | python3
Help on function bar in module __main__:

David Mc Dougall added the comment:
No, the code works fine. I just wish the docs weren't so muddled.
I wish the docs started by saying:
> The graph is a dict of {'start_node': ['end_nodes',]}
> The topological sorter puts the end_nodes before their start_nodes.
[note: this is what the code currently does]
Then the docs could introduce and use different terminology: "tasks" and their
"dependencies".
Everyone understands what those are.
And nowhere does it need to say the word "predecessors".
But honestly, I think I'm going to throw in the towel and give up on this
endeavor.

David Mc Dougall added the comment: I can post literally hundreds of examples of directed graphs that are traversable in the forward direction. This might be the only one which is *only* traversable backwards. > As to the meaning of "point to" Here is one: If I have a pointer in memory, I might represent that with an arrow, Like: ADDRESS -> VALUE Or if I have a dictionary I might write: KEY -> VALUE But in the graph the edges are directed the opposite way: KEY <- VALUE The edges in the graph point in the opposite direction as the underlying memory pointers.

David Mc Dougall added the comment: > you're not actually confused. I was when I first read it! > the meanings of "predecessor" and "successor" are universally agreed upon I disagree. The universally agreed upon terms are "directed edge u -> v". It's not obvious if the "predecessor" should be the start or the end point of the edge, and this is why the docs explicitly state the edge direction: > If the optional graph argument is provided it must be a dictionary > representing a directed acyclic graph where the keys are nodes and the values > are iterables of all [...] the nodes that have edges that point to the value > in the key. -- ___ Python tracker <https://bugs.python.org/issue46071> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue46071] Graphlib documentation (edge direction)
David Mc Dougall added the comment:
> The argument passed is the predecessor form of the graph B -> A
where graph = {'A' : ['B']}
This is part that I'm objecting to. The form of the graph should be A -> B, not
B -> A.
The issue with the current form is that you can not traverse the graph, at
least not forwards. When I say traverse forwards I mean that you follow the
edges in the direction of the arrows. If you look up 'A' in the current graph
you get all of the nodes that point *to* A, but that doesn't help you get
*from* A to anywhere else.
There are two conventions:
1) Graphs should be traverse-able, by following the arrows.
2) Topological sorting makes the arrows point to the right.
Convention #1 was broken to satisfy convention #2.
What is important about the topo-sort is that it makes all of the edges point
in the *same* direction. It doesn't actually matter which direction that is.
And credit where due, the library picked the more-useful direction. It was a
pragmatic choice, driven by the real use case of dependency resolution.
But having the graph with arrows pointing in the wrong direction is going to
cause endless confusion.
For an example of the confusion this causes, look at the API itself. The "add"
method explicitly calls out the fact that you can add nodes with no
predecessors. This is obviously also possible with the graph argument as it
currently is.

[issue46071] Graphlib documentation (edge direction)
David Mc Dougall added the comment: > If the way the user collects their data stores only successor links (which, > as above, seems odd in applications that actually use topsorts), then they > need something like this instead: Actually they only need to do this: ts = TopologicalSorter(my_forward_graph).static_order() ts = reversed(ts) I think part of the issue here is that the document uses two terms to describe the same thing: "predecessor" and "edge-direction". Everywhere it discusses predecessors it gets it right, but the edge direction is hopelessly confused because they tried to use the "normal" definition of topo-sort and the only way to make that work is to also reverse the direction of the graph's edges to compensate (and the two reversals cancel each other out). The edge direction is only mentioned twice in the whole document, once to define topo-sort and again to define the graph format. If the users problem fits into the task dependency paradigm, then this library makes a lot of sense. But for users who just have a directed graph, the documentation is really really confusing. I think it would be much better if the document explained that this was a "reversed" topological sort with a slightly different definition, and used a "bog standard" graph format like for example in this tutorial: https://www.python.org/doc/essays/graphs/ -- ___ Python tracker <https://bugs.python.org/issue46071> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

David Mc Dougall added the comment: The "reverse-toposort" is actually quite a good idea. The end-user is usually going to want to iterate over the sorted output in the "reverse" order anyways, especially if they're doing task ordering / dependency resolution. Also, the underlying algorithm produces the "reverse" ordering by default. In my experience from writing and using my own topological sorting programs using the "correct" definition: the toposorter reverses the list, and then the users iterates over it in reverse order. -- ___ Python tracker <https://bugs.python.org/issue46071> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue46071] Graphlib documentation
New submission from David Mc Dougall : The documentation for graphlib encourages users to represent their graphs in a awkward format. Graphs are currently represented using dictionaries of nodes, for example: graph["end_node"] = ["start_node"] And this is unintuitive because you can't use the graph traverse edges in their forward direction. If you look up a node in the graph, you get all of the nodes that point to the key, as opposed to all of the nodes that the key points to. The solution is to rewrite the documentation such that all of the edge directions are reversed. The final topologically sorted list will be in the "opposite" direction as a consequence. This will cause no functional changes. -- assignee: docs@python components: Documentation messages: 408535 nosy: dam1784, docs@python priority: normal severity: normal status: open title: Graphlib documentation type: enhancement versions: Python 3.10, Python 3.11, Python 3.9 ___ Python tracker <https://bugs.python.org/issue46071> ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

First thing, get rid of all those semicolons. This is Python you're
writing, not C++. Likewise, the extra parens in your while statements.
Your problem is that you're doing the accept() inside your main loop on
the server. You want to be doing it once, outside the loop.
I prefer using the semicolons... They aren't making my code wrong... I use
other programming languages from time to time, and I'd rather just always use
semicolons, as with the parentheses. I will try that though, moving the
accept(). What about sending information back to the client?

[issue11253] autodocument first appearance of ctypes.wintypes constants
Mark Mc Mahon mtnbikingm...@gmail.com added the comment:
This mostly a documentation concern - correct? ctypes.wintypes is sparsely
documented - in 2.7 the help for it seems to be:
The ctypes.wintypes module provides quite some other Windows specific data
types, for example HWND, WPARAM, or DWORD. Some useful structures like MSG or
RECT are also defined.
How about the following solution:
First of all get the previous release information
- hg log / hg revert / import wintypes / dir(wintypes)
Future changes have to be updated manually (which probably is not a big deal as
it is a reasonably stable module)
In fact I went and got the revision when each attribute was added... (some of
those are just ctypes leakage)

But was thinking - let's do that if/when we need to :) The latest patch updates the tests - but no change to the C code. (I doubt the error you received is a bug in msilib, and I couldn't repro even by opening EVERY MSI in my windows\installer dir. It could be a rights/security issue?

[issue12026] Support more of MSI api by exposing handles
Mark Mc Mahon mtnbikingm...@gmail.com added the comment: You can pass it to any function in the MSI SDK through ctypes. e.g. def ReadStream(record, field): buf = (ctypes.c_char * 2048)() orig_size = ctypes.sizeof(buf) status = 0 res = [] while status == 0: size = ctypes.c_long(ctypes.sizeof(buf)) status = msidll.MsiRecordReadStream( record.hanlde, field, ctypes.byref(buf), ctypes.byref(size)) res.append(buf.raw) if size.value != orig_size: break data = .join(res) return data or any of the other functions not currently implemented in _msi.c Some of the other important ones (to me at least) are: - MsiDatabaseGetPrimaryKeys - MsiDatabaseExport - MsiDatabaseImport If the whole MSI SDK is wrapped - then exposing the handles would have no use :). The alternative I have so far is to re-write _msi.c using ctypes (already done), but I thought it would be better if not all of _msi.c had to be re-implemented. One alternative patch is to include those extra functions in _msi.c (though I am not sure I have the C skills to achieve that easily - and it may still miss functionality, and it may have even less chance of being accepted) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue12026 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

Non hashable object (without __dict__)
Hello, I have a C++ application, I used SWIG to call the python code. I pass myModule.myObject object to the method of python code and what to store it in JSON format. The problem is when I do: o = myModule.myObject() inside python, the o object has __dict__ property, but if I take the passed object o like: def myMethod(self, objects): for o in objects: print o.__dict__ it fails saying no SwigPyObject does not have __dict__ property. The only way to use o properties is to call it by name like here: print o.MyProperty But in order to use json.dump( objects, file, default = self.MyJSONEncode ) I MUST to pass to MyJSONEncode method an object that has __dict__ as its property. So, what is the best way to correct my objects, which are coming from C ++ code to make them available for putting in JSON format ? Thank you. -- http://mail.python.org/mailman/listinfo/python-list

[issue7639] bdist_msi fails on files with long names
Mark Mc Mahon mtnbikingm...@gmail.com added the comment: For Directory.make_short() the only things which are left could be considered splitting hairs. 1. Do we need to remove '\/:' from the file name - if these characters are there then the file name is not valid in the first place. 2. These characters '+,;=[]' should really be changed to '_' if we want to match more closely how Windows makes short names. I can write a patch for the above if they should be fixed and either way I can add tests for this function. (the test I had for testing my own patch - almost completely pass - but the only failure was depending on point 2.) -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue7639 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue11696] msilib.make_id() is not safe for non ASCII characters.
New submission from Mark Mc Mahon mtnbikingm...@gmail.com: msilib.make_id() currently ensure that any of the following characters are not in the resulting ID: -+~; Per the Microsoft documentation the following list of characters are allowed. http://msdn.microsoft.com/en-us/library/aa369212(v=vs.85).aspx The Identifier data type is a text string. Identifiers may contain the ASCII characters A-Z (a-z), digits, underscores (_), or periods (.). However, every identifier must begin with either a letter or an underscore. If an file name contains any characters outside of the characters -+~; + string.ascii_letters + string.digits + ._ then it will be an invalid ID. This includes many punctuation characters which are valid in file names but not ID's, and every unicode character which does not overlap with ASCII.

[issue8554] suspicious comment in msilib.py/__init__.py
Mark Mc Mahon mtnbikingm...@gmail.com added the comment:
Per: http://msdn.microsoft.com/en-us/library/aa369212(v=vs.85).aspx
The Identifier data type is a text string. Identifiers may contain the
ASCII characters A-Z (a-z), digits, underscores (_), or periods (.). However,
every identifier must begin with either a letter or an underscore.
So the spec would say that colons are NOT allowed. Editing some entries in the
File table of an MSI (using Orca from the MSI SDK) and running the validation
confirms that.
All the following were flagged as errors during validation:
'KDiff3EXE;ASDF@#$', 'chmFile-', 'pdfFile(', 'hgbook]', 'TortoisePlinkEXE]',
'Hg.Cämd', 'merg:epatterns.rc'
I think that this issue should be fixed when issue2694 is fixed. (I would like
to put together some tests and patch for that :)

[issue1128] msilib.Directory.make_short only handles file names with a single dot in them
Mark Mc Mahon mtnbikingm...@gmail.com added the comment: I looked at the existing patches - and noted that they went closer to how Windows does short files - but still left out some cases. I believe the latest patch catches all cases. from http://msdn.microsoft.com/en-us/library/aa368590(v=vs.85).aspx Short and long file names must not contain the following characters: slash (/) or (\) question mark (?) vertical bar (|) right angle bracket () left angle bracket () colon (:) asterisk (*) quotation mark () In addition, short file names must not contain the following characters: plus sign (+) comma (,) semicolon (;) equals sign (=) left square bracket ([) right square bracket (]) No space is allowed preceding the vertical bar (|) separator for the short file name/long file name syntax. Short file names may not include a space, although a long file name may. A space can exist after the separator only if the long file name of the file name begins with the space. No full-path syntax is allowed. Though I wonder do we really need to check for or replace the first set of characters above - none are allowed in any file name, so if they are there it is probably a error in how the function was called! I also tested speed of re.sub, comprehension (.join(c for c in ...) and for loops - and for loops were the fasted (for the small set of characters being replaced). I am not patching make_id() - because I have added a patch for that to issue2694. Note - The attached patch will probably not apply cleanly - as it pre-supposes that the patch (http://bugs.python.org/file21408/make_id_fix_and_test.patch) from issue2694 is applied first (especially for the tests) -- nosy: +markm Added file: http://bugs.python.org/file21420/msilib.make_short.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue1128 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

c++ data types in python script
Hi people, I've used SWIG module to embed python inside c++ app. I pass a list of objects (with lots of different properties of types string, float, custom types like URL, Software and finally of list of strings). Now I'm in python. URL and Software has str() method that converts their value to string recognizable by JSON. But the problem is with list of strings. So, as I said I passed std::liststd::string myObjects to python function. Then I iterate it and for each object in myObjects I create a python copy (serialize it) to be able to put into JSON format and store in appropriate file. object has property benchmarks of type liststring. I do: ... class PythonObject: def __init__(self, object): self.benchmarks = list() for s in object.benchmarks: self.benchmarks.append(s) ... and it fails, also I do: ... class PythonObject: def __init__(self, object): self.benchmarks = [unicode(s) for s in object.benchmarks] ... and it fails, also I do: ... class PythonObject: def __init__(self, object): for s in object.benchmarks: print s[0] + s[1] + s[2] print type(s) ... and it fails printing wor type 'str' Segmentation fault (core dumped) $ also I do: ... class PythonObject: def __init__(self, object): self.benchmarks = unicode(object.benchmarks) ... and it does not fail, instead it puts in JSON this string: ... benchmarks: mymodule.StringList; proxy of Swig Object of type 'std::list std::string, std::allocator std::string *' at 0xb63ed4e8, ... but it is not what I need What I'm trying to stress is that c++ objects should be converted (serialized) before putting them into json. Otherwise type errors occur and process fails. I love learning python and hope somebody may suggest me or tell something. Thank you all anyway! Arthur -- http://mail.python.org/mailman/listinfo/python-list
Re: c++ data types in python script
Great! The solution is to use self.benchmarks = list(object.benchmarks). Now I'm battling with time_t type. C++ time_t converts to python int but it causes memore leaks due to destructor absence.

python data types in c++ code
Hi all, Ok, I managed to work with c++ data types in python and can store serialize c++ objects to store in json. Now the task is backward.

But I can't see how to convert PyObject as element of PyList to c++ data type or even how to convert or iterate PyList which is PyObject too. Please, whisper me the proper way I will go for.

If you are unfamiliar with arbitrary precision, I'm referring tohttp://en.wikipedia.org/wiki/Arbitrary-precision_arithmetic Suppose I find the eigenvalues of a matrix and the eigenvalues range from 1 to 0.0001. This can be handled by numpy in Python because the smallest eigenvalue is larger than then numerical precision of 1E-19. However, if the range of eigenvalues is 1 to 1E-40, then I will need to increase the precision of all calculations leading up to finding the eigenvalues. I am working with complex valued matrices and I expect to get real eigenvalues back (based on the physics of the system). The precision of numpy is apparent from the imaginary component of the eigenvalues I find, currently 1E-19 or 1E-20. I need better precision for small eigenvalues. In case you are curious, the complex-valued matrices are 20x20. Thanks You probably have to change the method of finding eigenvalues. Which one do you use? Power or algebraic ? Do you use Gaussian method to simplify matrices ? Languages can't support infinitely large or small numbers, so try to multiply the inner variables by 10^n to increase their values if this will not involve on the method.

Hi Peter, I implemented my decoder using your approach. Very positive. But that is for simple objects. My objects have nested lists.

I suggest that you use json instead which is part of the standard library since Python 2.6. The documentation is here: http://docs.python.org/library/json.html If you know that there are only MyObject instances you need a function to construct such a MyObject instance from a dictionary. You can then recreate the objects with objects = [object_from_dict(d) for d in json.load(f)] or, if all dictionaries correspond to MyObject instances objects = json.load(f, object_hook=object_from_dict) A general implementation for old-style objects (objects that don't derive from object) is a bit messy: # idea copied from pickle.py class Empty: pass def object_from_dict(d): obj = Empty() obj.__class__ = MyObject obj.__dict__.update((str(k), v) for k, v in d.iteritems()) # * return obj If you are willing to make MyClass a newstyle class with class MyObject(object): # ... the function can be simplified to def object_from_dict(d): obj = object.__new__(MyObject) obj.__dict__.update((str(k), v) for k, v in d.iteritems()) # * return obj (*) I don't know if unicode attribute names can do any harm, obj.__dict__.update(d) might work as well. -- http://mail.python.org/mailman/listinfo/python-list
Re: arbitrary precision linear algebra
Are you saying python cares whether I express a number as 0.001 or scaled by 10^5 to read 100? If this is the case, I'm still stuck. I need the full range of eigenvalues from 1 to 1E-300, so the entire range could be scaled by 1E300 but I would still need better precision than 1E19 If python package can't compute 1E-300, then you can't use it. You can try to split your task onto small subtasks, which can be handled by specific python package. Then you need to think of the way to do that. Mathematically. If no way, then you can leave your task alone. Programming is limiting, that is true. I have heard about grid computing. You may find scientists working on grid and ask how do they split their tasks. But I think they do not an answer as well. Also google uses its matrix to rank web pages. It computes the maximum eigenvalue from the matrix which contain near zero entries too. Maybe you can find how do they store those values. Sorry, can't help anymore. I also have computing problems which I can't yet solve :) -- http://mail.python.org/mailman/listinfo/python-list

SourceForge project page: http://sourceforge.net/projects/pywinauto Download from SourceForge https://sourceforge.net/projects/pywinauto/files/pywinauto/0.3.9/pywinauto-0.3.9.zip/download Here is the list of changes from 0.3.8: * Major change this release is that Sendkeys is no longer a requirement! A replacement that supports Unicode is included with pywinauto. (hopefully soon to be released as a standalone module). Please note - this is still quite untested so this release should be treated with some care.. * Made sure that default for WindowSpecification.Window_() was to look for non top level windows. The defaults in find_windows() had been changed previously and it now needed to be explicitly overridden. * Fixed a missing reference to 'win32defines' when referencing WAIT_TIMEOUT another typo of false (changed to False) * Removed the restriction to only get the active windows for the process, now it will be possible to get the active windows, even if a process is not specified. From http://msdn.microsoft.com/en-us/library/ms633506%28VS.85%29.aspx it gets the active window for the foreground thread. * Hopefully improved Delphi TreeView and ListView handling (added window class names as supported window classes to the appropriate classes). * Added support for running UI tests with reference controls. (requried for some localization tests) * Various PyLint and PEP8 fixes made.

SourceForge project page: http://sourceforge.net/projects/pywinauto Download from SourceForge http://sourceforge.net/project/showfiles.php?group_id=157379 Here is the list of changes from 0.3.7: 0.3.8 Collecting improvements from last 2 years -- 15-March-2009 * Fixed toolbar button pressing - This required for HwndWrapper.NotifyParent() to be updated (to accept a new ID parameter) * Fixed a bug wherea listview without a column control would make pywinauto fail to capture the dialog. * Converted documenation from Pudge generated to Sphinx Generated * Added some baic support for Pager and Progress controls (no tests yet) * Added some more VB 'edit' window classes * Added some more VB 'listbox' window classes * Added some more VB 'button' window classes * Ensured that return value from ComboBoxWrapper.SelectedIndices is always a tuple (there was a bug where it would sometimes be a ctypes array) * Changed default for finding windows to find disabled windows as well as enabled ones (previous was to find enabled windows only) (note this may impact scripts that relied on the previous setting i.e. in cases where two dialogs have the same title!) * Much better handling of InvalidWindowHandle during automation runs. This could be raised when a closing window is still available when the automation was called, but is gone half way through whatever function was called. * Made clicking more robust by adding a tiny wait between each SendMessageTimeout in _perform_click(). * Added attributes ``can_be_label`` and ``has_title`` to ``HwndWrapper`` and subclasses to specify whether a control can act as a label for other controls, and whether the title should be used for identifying the control. If you have created your own HwndWrapper subclasses you may need to override the defaults. * Added a ``control_id`` parameter to find_windows which allows finding windows based off of their control id's * Added a FriendlyClassName method to MenuItem * Split up the functions for button truncation data * Commented out code to get a new font if the font could not be recovered * Moved code to get the control font from Truncation test to handleprops * Added a function to get the string representation of the bug. (need to refactor PrintBugs at some point). * Fixed a variable name (from fname - font_attrib as fname was not a defined variable!) * Forced some return values from MissingExtraString test to be Unicode * Fixed the MiscValues test (converted to Unicode and removed some extraneous characters) * Updated the path for all unittests * Made two unit tests sligthly more robust and less dependent on computer/app settings * Updated timing settings for unit tests * Updated the examples to work in dev environment.

Re: is python Object oriented??
Re ‘builtin’ is not a class. I think object ; not only class And builtin is an object. -- @-salutations Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list
Re: is python Object oriented??
Hi! Il se trouve que Chris Rebert a formulé : Python has functions, which are not associated with a class functions are methods of builtin... -- @-salutations Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list

Re: Make Python create a tuple with one element in a clean way
Hi! You want 2*(3+4) to return (7,7)? For have that: 2*(3+4,) -- @-salutations Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list
Re: Calling Python code from inside php
Hi! If you are under Windows, you can: - call Python's functions via Active-Scripting - call a Python COM server (functions or properties) For that, use Pywin32. And, in all cases, call functions can use parameters. -- @-salutations Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list
Mathematical Python Library
I'm looking for a library which can do mathematical stuff like solving equations. Or calculation the nulls of a function and so on. Does anyone know one? Thanks in advance! -- http://mail.python.org/mailman/listinfo/python-list
Compiling fails on Mac OS X 10.5
Hi! I'm trying to compile on my Macbook with OS X 10.5. I have all updates and Xcode 3.0 installed. I checked python out with: svn checkout http://svn.python.org/projects/python/branches/py3k After that I did ./configure in the created py3k dir. Everything went fine. But make fails with the following error message: ranlib libpython3.0.a gcc -u _PyMac_Error -o python.exe \ Modules/python.o \ libpython3.0.a -ldl make: *** [sharedmods] Error 1 I tried checking out many times. I also tried de 3.0a2 release,gives me the same error. I've heard others have compiled it successfully on Leopard so I wonder what causes the problems on my system. -- http://mail.python.org/mailman/listinfo/python-list

Could you post the rest of the ./configure and compilation output? make might be rereporting an error that occurred further up. I don't see anything related on the Python bug tracker. It might be worth posting a bug report at bugs.python.org Mark Alright! ./configure output is here: http://rafb.net/p/NqSmqc25.html and make output here: http://rafb.net/p/kzeb2e29.html -- http://mail.python.org/mailman/listinfo/python-list
Re: Python Windows installation
Hi! 1.5.1 Sure? 1.5.1? For Python 2.5, look ActiveState. Their distrib have silent option. -- @-salutations Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list
Re: shared memory pointer
Hi! I agree ; on windows mmap use Memory-Mapped-file, who use virtual memory. And shared memory use physical memory. The difference is OS an not Python -- @-salutations Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list
Re: [python-win32] How can I get the parentWindow.document object?
Hi! ie = win32com.client.Dispatch(InternetExplorer.Application) doc=ie.Document.parentWindow.document Use bridge variable : window=ie.Document.parentWindow And work with : print window.Document.body.name -- @-salutations Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list
Re: [python-win32] How can I get the parentWindow.document object?
Re! Sorry! The good exemple is : ie = win32com.client.Dispatch(InternetExplorer.Application) window=ie.Document.parentWindow print window.name another : window.alert(Aalleerrtt) -- @-salutations Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list

Re: IDEs for COM scripting: C# v. Python v. Iron Python v. JPython
Hi! No. The IDIspatch-interface explicitely lists what methods with what arguments it has. So code completion is possible there as well. Sorry, I think different. In VS, assists use TLB for find methods arguments. Dynamic-server can't have TLB. Other way for verify : try a Makepy on a COM server write with Python+Pywin32... -- @-salutations Michel Claveau -- http://mail.python.org/mailman/listinfo/python-list
