Dave,
Thanks for your nice explanation. For your answer on one of my questions:
*Modules don't have methods. open is an ordinary function in the module.*
Isn't method and function used interchangeably? In other words, aren't they
the same thing?
Or, Python has some naming conventions here?
You've already received answers to this, but a short example might clarify the
difference:
#--- Code
# Define a function
def func1():
print('This is function func1()')
# Define a class with a method
class Examp:
def func2(self):
print('This is method func2()')
# Try them out
obj = Examp() # Create an object (an instance of class Examp)
func1()# Call the function
obj.func2()# Call the method through the object
func2()# Try to call the method directly -- Error!
#--- /Code
This code results in the following:
This is function func1()
This is method func2()
Traceback (most recent call last):
File fun-meth.py, line 14, in module
func2()
NameError: name 'func2' is not defined

Personally I find that duck typing eliminates a lot of the circular dependency problems. Class A doesn't necessarily have to know about Class B to work with instances of Class B. All that has to be known is what methods are going to be available on those instances. The interface pattern can help here if you wanted a bit more safety (like what Zope provides). Either way it breaks up the dependency cycle nicely. If Class A needs to instantiate instances of Class B (which depends on Class A), then it could call a factory method to do so, perhaps set up by a third party after both modules have been imported. There are lots of methods of avoiding the issue entirely. In the C or C++ world, I find that signalling frameworks can also be used to break a dependency cycle. For example, if Class A needs to call a method on an instance of Class B (which in turn depends on Class A), that could be done instead as a signal, which is later connected to Class B's method after everything is successfully instantiated. Also makes testing a bit easier, because you can simply hook up the signals to a test harness. A bunch of useful thoughts. Thanks, folks! -- https://mail.python.org/mailman/listinfo/python-list

Either way, you have to balance network traffic versus promptness of update, and it's nearly impossible to pick perfectly.

Re:scipy shape
Abdul Abdul abdul.s...@gmail.com Wrote in message: I came across an example that starts as follows: from scipy.ndimage import filters img = zeros(im.shape) What does the second line mean here? Is it setting the image pixels to zero? What is shape here? This example is incomplete. Neither zeros nor im are defined in the python versions I have installed, and shape is an attribute of im, whatever type that is. Your example needs at least another import, probably like from numpy import zeros http://docs.scipy.org/doc/numpy/reference/generated/numpy.zeros.html But I can't guess what im might be, unless it's some numpy instance.

Dave,
Thanks for your nice explanation. For your answer on one of my questions:
*Modules don't have methods. open is an ordinary function in the module.*
Isn't method and function used interchangeably? In other words, aren't they
the same thing?
Or, Python has some naming conventions here?
You've already received answers to this, but a short example might clarify the
difference:
#--- Code
# Define a function
def func1():
print('This is function func1()')
# Define a class with a method
class Examp:
def func2(self):
print('This is method func2()')
# Try them out
obj = Examp() # Create an object (an instance of class Examp)
func1()# Call the function
obj.func2()# Call the method through the object
func2()# Try to call the method directly -- Error!
#--- /Code
This code results in the following:
This is function func1()
This is method func2()
Traceback (most recent call last):
File fun-meth.py, line 14, in module
func2()
NameError: name 'func2' is not defined
-=- Larry -=-
You COULD have something like this though:
# --- myModule.py ---
def myFunc():
print 'myFunc'
# --- main.py ---
import myModule
myModule.myFunc()
In this case, myFunc LOOKS like a method when it is called from main.py, but it
is still a function.
My purpose was to give a _simple_ example of the difference in the two terms: that a function
is called directly and a method is called through an object.
Your example may _look_ the same (it uses the same dot syntax), but here it is to resolve a
namespace -- a module is not an object. So yes, this is still a function and not a method. But
we're getting rather pedantic here.

[issue22453] PyObject_REPR macro causes refcount leak
Serhiy Storchaka added the comment: Thank you for your report Chris. PyObject_REPR() is used only in Python/compile.c just before calling Py_FatalError(). So refcount leaks doesn't matter in these cases. PyObject_REPR() is expanded to deprecated _PyUnicode_AsString which is not defined if Py_LIMITED_API is defined. So it is unlikely that third-party code uses it. We can just remove this macro in 3.5. There are other bugs in formatting fatal error messages where PyObject_REPR() is used. PyBytes_AS_STRING() is called for unicode objects. Definitely this branch of the code is rarely executed. Here is a patch which expands PyObject_REPR() in Python/compile.c and replaces PyBytes_AS_STRING() with PyUnicode_AsUTF8(). In 3.5 we also should remove the PyObject_REPR macro definition. -- assignee: - serhiy.storchaka keywords: +patch nosy: +serhiy.storchaka stage: - patch review type: behavior - resource usage versions: -Python 3.1, Python 3.2, Python 3.3 Added file: http://bugs.python.org/file37220/PyObject_REPR.patch ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22453 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue22895] regression introduced by the fix for issue #22462
New submission from Matthias Klose: the fix for issue #22462 introduces a regression in the test_pyexpat test cases. I'm not yet sure why. This is only seen when running the testsuite from the installed location, which shouldn't matter.

[issue22897] IDLE - MacOS: freeze on non-ASCII save with open debugger
New submission from Boris: When attempting to save a file containing an Aring; character with the debugger open, IDLE freezes with/or without partially opening the warning window. (Mac OS X 10.9.5, IDLE running python 2.7.5). Reproducible steps: - Create and save file with one line: 1+1 # A - Open IDLE - Open the debugger - Open the file - Delete the A, type shiftaltA - type commands to save. This triggers the problem. Application hangs (not responding) and needs to force quit. Sometimes the graphics memory of other applications gets corrupted. -- components: IDLE messages: 231338 nosy: steipe priority: normal severity: normal status: open title: IDLE - MacOS: freeze on non-ASCII save with open debugger type: behavior versions: Python 2.7 ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22897 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com

[issue20948] -Wformat=2 -Wformat-security findings
STINNER Victor added the comment: The format parameter passed to sprintf() is created by makefmt() function. In Python 3.5, makefmt() has a few parameters. The code is simple and looks safe. The makefmt() function was much more complex in Python 3.3, it had more parameters: zeropad, width and precision. I refactored PyUnicode_FromFormatV() to optimize it. During the optimization, makefmt() was simplified, and in fact it is now possible to inline it and remove it. I just removed it in Python 3.5. Should we change something in Python 2.7 and 3.4? Ignore the warning? Or can I just close the issue?

[issue22898] segfault during shutdown attempting to log ResourceWarning

Georg Brandl added the comment: With the vanilla BaseHTTPRequestHandler, this shouldn't happen. self.raw_requestline is read from a socket file, which returns bytes, so they can be decoded using str(bytes, encoding). Can you please check if there are any third-party packages involved that call/subclass the classes from http.server and introduce a bytes/str confusion? They might not be correctly/completely ported to Python 3 in that case.

[issue22897] IDLE hangs on OS X with Cocoa Tk if encoding dialog is required during save
Ned Deily added the comment: Thanks for the report. It appears that all that is needed to trigger the hang is any operation that invokes the IDLE EncodingMessage dialog (Non-ASCII found, yet no encoding declared. Add a line like [...]) in IOBinding.py during a Save when IDLE is linked with the OS X Cocoa Tk 8.5 (or likely 8.6) as used with the python.org 64-bin/32-bit 10.6+ installers, for example, just opening a new edit window, inserting a non-ASCII character, and then trying to Save. EncodingMessage subclasses the Tkinter SimpleDialog module and creates a new Toplevel root; I seem to recall other problems like this in the past. The problem is not seen with the older Carbon Tk 8.4 or with an X11 Tk on OS X. -- nosy: +ned.deily stage: - needs patch title: IDLE - MacOS: freeze on non-ASCII save with open debugger - IDLE hangs on OS X with Cocoa Tk if encoding dialog is required during save ___ Python tracker rep...@bugs.python.org http://bugs.python.org/issue22897 ___ ___ Python-bugs-list mailing list Unsubscribe: https://mail.python.org/mailman/options/python-bugs-list/archive%40mail-archive.com
