In Python, one bug that often bites me is this: (example A) aList = [1,2,3] for i in aList: i += 1 print aList --> [1,2,3]
This goes against my intuition, which is that aList == [2,3,4], probably because so much in Python is passed by reference and not by value. Of course I can always use range() or enumerate(): (example B) aList = [1,2,3] for i in range(len(aList)): aList[i] += 1 print aList --> [4,5,6] But example A seems more elegant, if only it did what I wanted it to do. :) So pardon my ignorance if the answer is obvious, but what is the simplest way in Python to get a reference to an element in a list? Is it really Example B? Thanks, Matt (My apologies if this double-posts; I accidentally sent it previously from a non-subscribed address.
