Here is one! To me an assertion is what actually documents that you don't 
expect NULL in this context and that the missing check is not an oversight.

+1 for assert()

I think that's right.  The change was not made for 2.7.

I seemed to recall the change was done in 2.6, but I found only that:

[Python-Dev] Failed to install PIL on windows, may have something to do with python implementaton

2011-07-13 Thread smith jack
I am a programmer with more than two years of python programming
experience, often the debugging process may led me to the details of
some details of python implementation, this is exciting : )

Now i face a problem, that is i want to install PIL on windows, but
failed, the error messages tells that the python installation cannot
find python information in the windows register, lol, this is true,
since i got a zipped python and extract it the a directory, not using
a msi file to install python.

So how should i do in order to install PIL for my python environment?
I find that PIL installation file is a zipped file with execution
capability  (is it of 7z format?)  Now i can open this exe file using
7z, and there are lots of .py files there, with directory somewhat as
follows:

PLATLIB
PIL\*.py
PIL.pth   (a plaintext file with content "PIL")

SCRIPTS
*.py

so can i just extrat the py files to my python installation directory?
then will PIL work correctly? (should i extract PIL\*.py to
python_24\Lib\site-packages, and extract *.py to python_24\Scripts?)

Will this work?  since this have something to do with the
implementation of Python,   i come to this maillist and ask for
help.  Hope i can receive some suggestions, Thank you :)

Yes, but this list is about the *development* of Python.  For help on
topic like this, which are about using Python, you'll have better luck
getting an answer if you post to python-list.  There are also probably
a lot more people with experience using Python on windows on that list
than there are here.  Since we release Python as an MSI, we're not too
likely to know how to work with it on Windows if you don't install it
from the MSI.

Python-Dev is for discussion of developing the next release of Python. 
This question should go to python-list, as your last question did.


Good luck.
