new.instancemethod - how to port to Python3

So, what's a working transcript of this code? Many thanks for a hint, Helmut. P.S.

As written, your code has a class that defines a to_binary method. Then,
*outside* of the method, in the class definition, you refer to self,
and use a return statement. This is not possible -- self does not exist,
and return gives a SyntaxError.
But, if the indentation is wrong, it looks like you are trying to get the
to_binary method to replace itself with a global to_binary function. I do
not understand this.

But how to transform the line with new.instancemethod. I've seen
examples where
new.instancemethod(to_binary, )

__doc__ string for getset members
Folks,
I am writing an extension where I follow the guide on the web
(http://docs.python.org/3.3/extending/newtypes.html#generic-attribute-management).
I have an object declared,
struct Object
{
PyObject_HEAD
};
and a member set through tp_getset mechanism,
PyGetSetDef ObjectGetSet[] =
{
{mem, (getter)MemGet, (setter)MemSet, mem-doc-string, NULL},
{NULL} /* Sentinel */
};
My question is - how do I access the doc string mem-doc-string
supplied in the PyGetSetDef structure? If I type
print(obj.mem.__doc__)
then the __doc__ string for the result of a call to MemGet(...) is
printed, not the doc string supplied in the PyGetSetDef structure.
Many thanks for the advice,
Nick Gnedin

Re: IDE for GUI Designer
Well, I usually use the Qt Designer and it does work well for me. It generates a .ui file with it which has to be passed to pyuic to generate the actual Python code -- and you have to generate a subclass to implement the slots -- for that, I add an external builder to Eclipse, so, in the end it's mostly a matter of saving the ui in designer and going on to implement the actual code for the actions in PyDev/Eclipse (sure, you don't click on a link to add Python code, but for me that separation is good).

Like every programming problem, the solution is to break it apart into
small, simple steps that even a computer can follow.
1) Split the string into words at whitespace.
words = string.split()
2) Search for the word in, and if found, duplicate it.
tmp = []
for word in words:
if word == 'in':
tmp.append('in')
tmp.append(word)
words = tmp
3) Take the words two at a time.
phrases = [words[i:i+2] for i in range(0, len(words), 2)]
4) Join the phrases into strings.
phrases = [' '.join(phrase) for phrase in phrases]

Re: I hate you all
Hi, Well all previous (python 2) code is meant to work for a tab size of 8. yes, but even in Python 2, mixing spaces and tabs is considered bad style and should be avoided. And code-checkers like pylint (which I can recommend to everyone) create a warning. You may call this categorically wrong, but it has been there a long while, is is still in use, and it sticks to the default. As I said, mixing tabs and spaces for indentation was *always* a bad idea, and is discouraged also in Python 2. Spaces-only can achieve compatibility between different people settings for formatted text like source code. But so does a common default for the tab size, But there's no such thing as default tab size. Configuring the tab-size is quite common among programmers. But why do you insist on using tabs at all? The best way -- in my opinion -- is to use the tab- and backspace-key for indentation, and let the editor convert it to spaces. (And use some tool to convert all tabs in the old code.) I don't see *any* advantage of mixed spaces and tabs, but quite some disadvantages/problems. What I would expect is some option in python to make tabs work the way they used to. I want a choice for me to preserve my settings, the same way you want to preserve yours. What I want should not be much to ask, since this is how python 2 used to do things. I admit such a '--fixed-tabs' option, that will make tab stops be 8 columns apart, and allow any number of spaces like in python 2, makes the code I write dependent on that option. There's no need to add this to Python 3, since you already have what you want. Simply use: expand yourscript.py | python3 regards Roland -- http://mail.python.org/mailman/listinfo/python-list

Re: with ignored
On Sun, Apr 7, 2013 at 6:40 PM, Barrett Lewis musikal.fus...@gmail.com wrote: I was recently watching that Raymond Hettinger video on creating Beautiful Python from this years PyCon. He mentioned pushing up the new idiom with ignored(ignored_exceptions): # do some work I tracked down his commit here http://hg.python.org/cpython/rev/406b47c64480 But am unsure how the yield works in the given situation. I know about creating generators with yield and have read the docs on how it maintains state. I think it works because it is returning control back to the caller while maintaining the try so if the caller throws it is caught by the context. Is this correct? I would love an in depth explanation of how this is working. I am trying to learn as much as possible about the actual python internals. The first thing to understand is that ignored() is a context manager and how context managers work. A context manager is an object with an __enter__ method and an __exit__ method. For example, the ignored() context manager could have been written as: class ignored: def __init__(self, *exceptions): self.__exceptions = exceptions def __enter__(self): return def __exit__(self, exc_type, exc_value, traceback): if exc_type is not None: return issubclass(exc_type, self.__exceptions) The __enter__ method is called when the with block is entered and sets up the context. The __exit__ method is called when the with block is exited and is passed the exception if one was raised. It returns True to suppress the exception, or False to continue propagating it. However, ignored() is actually implemented as a generator function with the @contextmanager decorator shortcut. This decorator takes a generator function and wraps it up as a class with the necessary __enter__ and __exit__ methods. The __enter__ method in this case calls the .next() method of the generator and returns after it yields once. The __exit__ method calls it again -- or it calls the .throw() method if an exception was passed in -- and expects the generator to exit as a result. So from the perspective of the generator it does its context setup (in this case, setting up a try block) prior to the yield, and then does the cleanup (in this case, selectively catching and suppressing the exceptions) after the yield. -- http://mail.python.org/mailman/listinfo/python-list

[issue17649] Python/Python-ast.c: No such file or directory
Ned Deily added the comment: Python-ast.c is a generated file. As released, a Python source tarball should contain an up-to-date version that does not need to be regenerated. However, if the timestamps of the source files are not preserved, the Makefile may think it is out of date and try to regenerate it. The regeneration step requires a working Python compiler so you may run into a bootstrap issue if there is none on the system. If you obtain the source using a Mercurial checkout, hg does not attempt to set timestamps on the source files so you are even more likely to run into problems in that case. Usually, the solution is to do a clean checkout or tarball extraction, then manually touch the files that Python-ast.c is built from: touch Include/Python-ast.h Python/Python-ast.c The newly-released Python 2.7.4 includes a make touch target in the Python Makefile just for this purpose, see Issue16004 and a number of other changes to help make this area more robust, for example, when building with a BUILDIR separate from SRCDIR. -- nosy: +ned.deily resolution: - out of date stage: - committed/rejected status: open - pending ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue17649 ___ ___ Python-bugs-list mailing list Unsubscribe: http://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue16551] Cleanup the pure Python pickle implementation
Serhiy Storchaka added the comment:
In response to Alexandre's comment on Rietveld. Access to a local variable is
faster than to a global one and the current implementation uses this for
struct.pack. I just use same trick for struct.unpack. Here is a microbenchmark
which demonstrate some effect of this optimization. I got 0.6491418619989417,
0.6947214259998873, and 0.5394902769985492 for optimized, non-optimized and
advanced optimized functions.
Of course, we can achieve even better effect if we will cache not only
struct.pack, but struct.Struct('i').pack, struct.Struct('B').pack, etc. I were
considered this as a reason for other patch, but we can do it in this issue.
