[Q] How to exec code object with local variables specified?
Hi,
Is it possible to run code object with local variables specified?
I'm trying the following code but not work:
def fn():
x = 1
y = 2
localvars = {'x': 0}
exec(fn.func_code, globals(), localvars)
print(localvars)
## what I expected is: {'x': 1, 'y': 2}
## but actual is: {'x': 0}
Python: 2.7.3

What I mean by open-ended is that you have no way of predicting how many times it will loop, because it depends on data you don't have ahead of time. The other type of loop is the for loop, where the loop will normally progress till it processes all items in a sequence. A while loop might look something like: def ask_user(): amount = get_amount() while amount != 0: do_some_stuff(amount) amount = get_amount() print done with program # And your top-level code might look something like: if __name__ == __main__: ask_user() If that makes sense to you, then write the functions that this one calls.

Re: 'indent'ing Python in windows bat

I'm converting windows bat files little by little to Python 3 as I

Some months ago I posted what I think is a similar question in the

Someone on this list answered (for Bash):
#!/bin/bash

python -c if True:

if condition:
do_this
else:
do_that

# end code
Perhaps something similar would work for a .bat file.
Provided there's only one Python block in the .bat or .cmd file then
there's no real problem; you just have to hide each language from the
other:
goto :start
:start
@echo off
echo This is a CMD script
python -x %~f0 %1
echo Back in the CMD script
goto :eof
import sys
print(Welcome to Python)
print(Arguments were {}.format(sys.argv))
print(Bye!)
You can put the Python code either before or after the triple-quote
string containing the CMD commands, just begin the file with a goto to
skip into the batch commands and end them by jumping to eof.

Fool Python class with imaginary members (serious guru stuff inside)
I'm trying to create a class that would lie to the user that a member is in some cases a simple variable and in other cases a class. The nature of the member would depend on call syntax like so: 1. x = obj.member #x becomes the simple value contained in member 2. x = obj.member.another_member #x becomes the simple value contained in first member's another_member. So the first method detects that we only need a simple value and returns that. The second method sees that we need member as a class and returns that. Note that simple type could mean anything, from int to bitmap image. I have determined that this is possible if I sacrifice the final member reference to the __call__ override using function-call syntax: 1. x = obj.member(). The call syntax returns the simple value and the other returns the class. It is also possible if I override the __xxxitem__ methods to simulate a dictionary. However, I would like to use the true member access syntax if possible. So, is it possible? -- http://mail.python.org/mailman/listinfo/python-list

In the way you mean that, no.
I'm trying the following code but not work:
def fn():
x = 1
y = 2
localvars = {'x': 0}
exec(fn.func_code, globals(), localvars)
The globals and locals you pass to exec are the globals and locals for
the context in which the code object runs. They have nothing to do with
the code objects local namespace.
Running exec with separate globals and locals is like running the code
within a class definition context. If you ran
def fn(): x = 1
class dummy:
fn()
dummy.x would not be defined and I presume you would not expect it to.

Assuming CPython, you would have to write something that searches the Python code before compilation, the ast during compilation, or the bytecode after compilation. Much easier would be to define a union class that is a simple type with attributes and return that in the first lookup. class AttrInt(int): def __getattr__(self, name): return 'attribute' y = AttrInt(3) print(y, y.a) ### 3 attribute If x.y returns an AttrInt, it will act like an int for most purposes, while x.y.z will return whatever AttrInt.__getattr__ does and the temporary AttrInt y disappears. -- Terry Jan Reedy -- http://mail.python.org/mailman/listinfo/python-list

Maximum percentage of CPU used isn't normally something you control. The only way I know of to do it involves having another process monitor the thing you want to control and sending signals to stop and start it (e.g., http://cpulimit.sourceforge.net/). Typically, you instead want to control the priority (so that higher priority apps can easily take more CPU time). That's what nice is for (http://docs.python.org/library/os.html#os.nice). If you want to limit a process in the same way that ulimit does, then the resources module is what you want (http://docs.python.org/library/resource.html#resource.setrlimit).

The scheduling priority can be altered with nice, get/setpriority or io priority. The psutil package http://code.google.com/p/psutil/ wraps all functions in a nice Python API.

When should I use development mode?
I am new to python and I have come across the following command and its description: Now to be able to run the project you will need to install it and its dependencies. python setup.py develop I looked up what the 'develop' argument does and found: Extra commands: develop install package in 'development mode' I searched for a description of 'development mode' but could not find a good description. Can anyone (very briefly) explain to me, in a sentence or two: what 'development mode' is? how 'development mode' differs from other 'modes'? why/when I would use 'development mode'? what 'development mode' does or does not allow me to do?

With os.sep ?
os.sep is the directory separator, but os.pathsep may be what you
want. Between that and os.getenv('path') you can at least get the
directories. Then on Windows, you also need to check out
os.getenv('pathext') and split _that_ on the semicolon, and try each
of those as a file extension. I'm not sure whether or not Windows will
add extensions from pathext if one is given on the command line - for
instance, if typing foo.exe will search for foo.exe.bat - but the
basics are there.
Alternatively, there may be a Win32 API funct5ion that does this.
Would be worth a look.

Yup, it does. It looks like it tries it without the extension first, though:

Well, at least it's consistent. Makes your PATH extremely sensitive,
though, easy for anyone to inject executables into it. But then, you
can already do that by putting them in the current directory, so
that's not really any different.
Jason's solution looks fine apart from the PATHEXT requirement, so if
you know you have the full filename and you don't care if the actual
command interpreter will do exactly the same, that'll do you fine.
Is this something that might want to be a function in the os module?
Particularly so if, as I suspect there might be, there's a Win32 API
function that precisely replicates the behaviour of executable
invocation. A while since I've done much Windows programming but I
think there's a SearchPath function?

os.pathsep was the missing piece for portably splitting the searchpath

For what I am doing I can even skip trying the pathexts, the ext is
already given, but good to know :-)

Yeah true, but ideally I'd like to avoid platform detection and
just have a generic function.

[issue15981] improve documentation of __hash__
New submission from Max: In dev/reference/datamodel#object.__hash__, there are two paragraphs that seem inconsistent. The first paragraph seems to say that a class that overrides __eq__() *should* explicitly flag itself as unhashable. The next paragraph says that a class that overrides __eq__() *will be* flagged unhashable by default. Which one is it? Here are the two paragraphs: Classes which inherit a __hash__() method from a parent class but change the meaning of __eq__() such that the hash value returned is no longer appropriate (e.g. by switching to a value-based concept of equality instead of the default identity based equality) can explicitly flag themselves as being unhashable by setting __hash__ = None in the class definition. Doing so means that not only will instances of the class raise an appropriate TypeError when a program attempts to retrieve their hash value, but they will also be correctly identified as unhashable when checking isinstance(obj, collections.Hashable) (unlike classes which define their own __hash__() to explicitly raise TypeError). If a class that overrides __eq__() needs to retain the implementation of __hash__() from a parent class, the interpreter must be told this explicitly by setting __hash__ = ParentClass.__hash__. Otherwise the inheritance of __hash__() will be blocked, just as if __hash__ had been explicitly set to None. -- assignee: docs@python components: Documentation messages: 170798 nosy: docs@python, max priority: normal severity: normal status: open title: improve documentation of __hash__ type: enhancement versions: Python 3.3 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15981 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

The fix could maybe be as simple as replacing line 384 in asyncore.py: data = self.socket.recv(buffer_size) with try: data = self.socket.recv(buffer_size) except socket.error as e: if 10035 == e.errno: pass else: raise e The differences between windows and unix non-blocking sockets are summarized quite nice here: http://itamarst.org/writings/win32sockets.html The original documentation from microsoft can be found here: http://msdn.microsoft.com/en-us/library/windows/desktop/ms740668(v=vs.85).aspx -- components: Library (Lib) messages: 170799 nosy: McNetic priority: normal severity: normal status: open title: asyncore.dispatcher does not handle windows socket error code correctly (namely WSAEWOULDBLOCK 10035) type: behavior versions: Python 3.2 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15982 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
[issue15978] asyncore: included batteries don't fit
chrysn added the comment: i'm aware this is ambitious, and hope that at least the individual sub-agendas will be manageable. as for vague, i can enhance it (i'd start refining the individual sub-agendas -- or do you think the big picture needs more details too?). integration of frameworks is hard, i know. for some libraries, it might not even be feasible, or it could be that it'd be easier to write a new server than integrating into the existing one. (eg it might be easier to refactor http servers into a generic and a blocking part first, and then offer a http.server.AsyncServer in parallel to the existing implementation). that's why i'd like to try to get a rough roadmap instead of hacking ahead :-) nevertheless, the current situation is not satisfying -- we have a versatile http client module, and yet who wants to fetch asynchronously is left with a stub implementation in the asyncore docs. that's not what one would expect from the batteries included catchphrase. we don't need all of that implemented *right now*, but maybe we can do better than implementing it never. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15978 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15276] unicode format does not really work in Python 2.x
STINNER Victor added the comment:
I can't reproduce this with Python 2.7.3.
locale.setlocale(locale.LC_NUMERIC, 'fr_FR')
'fr_FR'
u'{:n}'.format(1)
u'10 000'
I don't understand why, but the all french locales are the same. Some french
locale uses the standard ASCII space (U+0020) as thousand seperator, others
use the non-breaking space (U+00A0). I suppose that some systems prefer to
avoid non-ASCII characters to avoid Unicode issues.
On Ubuntu 12.04, locale.localeconv()['thousands_sep'] is chr(32) for the locale
fr_FR.utf8.
You may need to install other locales to test this issue. For example, the
ps_AF locale uses U+066b as the decimal point and the thousands separator.
I chose to not fix the issue in Python 3.2 because it needs to change too much
code (and I don't want to introduce a regression and 3.2 code is very different
than 3.3). You should upgrade to Python 3.3, or reimplement the Unicode
format() function for numbers using locale.localeconv() ('thousands_sep',
'decimal_point' and 'grouping') :-/
Or find a more motivated developer. Or I can do the job if you pay me ;-)

[issue14783] Make int() and str() docstrings correct
Ezio Melotti added the comment: That would be backward incompatible, and there might be some valid (corner) cases to pass it as a keyword. Since people are usually not supposed to use it as a keyword arg, it doesn't matter much if the name is different if that makes the docs more understandable. If someone tries to do int(number=10) and gets an error it would likely switch to the simpler int(10). If he really needs keyword args he can always check the code. That said, I don't have a strong opinion about this, so if people think that x should be used, it's fine with me. -- ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue14783 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

EILSEQ is returned if LCMapString failed, and ERANE if the output buffer is too small. I don't see where ERANE can be returned. If the output buffer is too small then the required buffer size (not including terminating null-char) should be returned. I see the same issue with wcscoll() in locale.strcoll().

[issue15944] memoryviews and ctypes
David Beazley added the comment:
There's probably a bigger discussion about memoryviews for a rainy day.
However, the number one thing that would save all of this in my book would be
to make sure cast('B') is universally supported regardless of format including
endianness--especially in the standard library. For example, being able to do
this:
a = array.array('d',[1.0, 2.0, 3.0, 4.0])
m = memoryview(a).cast('B')
m[0:4] = b'\x00\x01\x02\x03'
a
array('d', [1.000112050316, 2.0, 3.0, 4.0])
Right now, it doesn't work for ctypes. For example:
import ctypes
a = (ctypes.c_double * 4)(1,2,3,4)
a
__main__.c_double_Array_4 object at 0x1006a7cb0
m = memoryview(a).cast('B')
Traceback (most recent call last):
File stdin, line 1, in module
ValueError: memoryview: source format must be a native single character format
prefixed with an optional '@'
As some background, being able to work with a byte view of memory is
important for a lot of problems involving I/O, data interchange, and related
problems where being able to accurately construct/deconstruct the underlying
memory buffers is more useful than actually interpreting their contents.

New submission from Julian Berman: As is, as far as I can tell, there's no way to easily compare two AST nodes to see if they have the same children and same fields (recursively). I'm writing some unit tests for a NodeTransformers, so I've settled for comparing `ast.dump()`s of each, which is kind of dirty, but 1) works and 2) produces reasonable failure messages. (As a side note of what else I've tried, comparing, say, a list of the `iter_child_nodes` is not a good alternative, since the tests I'm writing are making assertions that a given node was not modified, which means they deepcopy the node and then want to assert that the transformed node is unchanged.) I don't know the global implications of changing ast.AST.__eq__ to know if that's feasible (hopefully someone will comment on that), but if it isn't, another provided way would be nice. -- components: Library (Lib) messages: 170826 nosy: Julian priority: normal severity: normal status: open title: Provide a way to compare AST nodes for equality recursively type: enhancement versions: Python 3.3, Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15987 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue15988] Inconsistency in overflow error messages of integer argument
New submission from Serhiy Storchaka: PyArg_ParseTuple raises inconsistent overflow error messages for small integer formats. For example: import _testcapi _testcapi.getargs_b(100) 100 _testcapi.getargs_b(1000) Traceback (most recent call last): File stdin, line 1, in module OverflowError: unsigned byte integer is greater than maximum _testcapi.getargs_b(-1000) Traceback (most recent call last): File stdin, line 1, in module OverflowError: unsigned byte integer is less than minimum _testcapi.getargs_b(1) Traceback (most recent call last): File stdin, line 1, in module OverflowError: Python int too large to convert to C long _testcapi.getargs_b(-1) Traceback (most recent call last): File stdin, line 1, in module OverflowError: Python int too large to convert to C long On platforms with 32-bit int and 64-bit long there will be more such cases. -- components: Interpreter Core messages: 170827 nosy: storchaka priority: low severity: normal status: open title: Inconsistency in overflow error messages of integer argument type: enhancement versions: Python 3.4 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue15988 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
