'as' keyword - when/how to use it I am having the hardest time trying to find documentation on proper use of the 'as' keyword (aside from . I initially thought that I would be allowed to do something such as: import shared.util as util The as statement seems to be causing a lot of ''module' object has no attribute'.

Function closure inconsistency I was playing around with Python functions returning functions and the scope rules for variables, and encountered this weird behavior that I can't figure out. Why does f1() leave x unbound, but f2() does not? def f1(): x = 0 def g(): x += 1 return x return g1 def f2(): x... 23 Jul 2010 19:07
