what's the python for this C statement?

Actually that doesn't really matter unless the loop is extremely big (> a 
million), since range is much faster than xrange for smaller values 
(which might be the more typical case). And I think range will be an 
iterator in the future, imitating the behavior of xrange. So it doesn't 
really matter anyway.

I would suggest a different thing: rewrite it in python instead of 
translating it.
