The following are apparently legal Python syntactically:
L[1:3, 8:10]
L[1, ..., 5:-2]
But they don't seem to work on lists:
>>> l = [0,1,2,3]
>>> l[0:2,3]
Traceback (most recent call last):
File "", line 1, in
TypeError: list indices must be integers
>>> l[...]
Traceback (most recent call
In Python 2.4.1:
>>> None = 99
SyntaxError: assignment to None
>>> True = 99
>>> False = 99
>>> True == False
True

So why is 'None' special?

OK. I got it.

Because I need to keep multiple versions of Python on this machine, and
I did a source code build of Python 2.4.1 on OS X (10.3.8) and the
executable produced was 'python.exe'. Can someone tell me whether this
is a bug, feature, or UserError?
% ./configure
% make
% ./python.exe

Why not trap the KeyError?

Was doing some string formatting, noticed the following:
>>> x = None
>>> "%s" % x
'None'
Is there a reason it maps to 'None'? I had expected ''.
