Call me crazy, but be careful when programming python in different text
editors and in general, ie cutting and pasting, tabing and spacing.
Loops can look fine and not work (try moving around test print
statements for iterators), in this case try re-tabing your indents so
that everything is uniform in the editor you are using.
