Idem...
The 'obvious' thing you might be missing is that Python relies heavily
on programmers following conventions, where other languages impose
strict rules... Some conventions are :
UPPERCASE_VARIABLE : a constant, don't touch unless you really know what
you're doing
_NameWithLeadingSingleUnderscore : 'protected' access , don't touch
unless you really know what you're doing
__NameWithLeadingAndTrailingDoubleUnderscore__ :
a 'magic' thing, don't touch unless you really know what you're doing
A special case is __NameWithLeadingDoubleUnderscore :
In older Python version, it was just a convention for 'private' access,
now it makes Python doing some mumbo-jumbo name mangling (which don't
strictly enforce 'privacy', but)...
Another special case is the 'self' pseudo-key word : the first argument
for object methods could be named whatYouWant, but (almost ?) everybody
uses 'self'.

I guess vim and emacs should run on Mac OS X ?

You could try boa contructor (a wxPython delphi-like RAD/IDE).
