4 thoughts on “I think I really dislike Python”

1. I have a feeling that you’ll *really* hate C

2. I actually like C, since it is consistent. Much more verbose, but consistent non-the-less.

3. That’s exactly why I like python.
   It takes all the black magic out of programming. But if you insist:

   class RubyStyleList(list):
       def __setitem__(self, idx, val):
           if len(self) < idx:
               self.extend( [None]*(idx-len(self)) )
           return super(RubyStyleList, self).__setitem__(idx, val)
   
   >>> l = RubyStyleList([1,2,3])
   >>> l
   [1, 2, 3]
   >>> l[10]=99
   >>> l
   [1, 2, 3, None, None, None, None, None, None, None, 99]

4. Actually, it has been more than a year now that I work with Python everyday at my day job. I still dislike it, but started to understand the verbosity and torturing of programmers that it brings as a necessary evil.
