Hello, I am fine tuning list comprehensions (at least my understandng thereof), and I'm not near a Python interpreter at the moment, so I was wondering if someone could tell me if I did OK -
def approachA(files): isHTML = [] for filename in files: if filename.endswith('.htm') or filename.endswith('.html'): isHTML.append(filename) return isHTML def approachB(files): isHTML = [filename if filename.endswith('.htm') or\ filename.endswith(.html') for filename in files] return isHTML I wanted approachB to be the list comprehension verstion of approachA. Did I get the syntax right? All seems somewhat back to front to me, although when read the comprehension does sorta make sense in a twisted way. Feels almost.. Perlesque in it's perverse compactness. That said, saving myself from the cascading sequential conditionals/loops of approach A is good, I feel. When it's 2am in the morning, and I've run out of coffee, 90% of my bugs have been due to the 'cascades' and one misplaced tab.

And with it comes the only basic human duty, to take the consequences. _______________________________________________ Tutor maillist - Tutor@python.org http://mail.python.org/mailman/listinfo/tutor
