Hello! Many times I was suggested to use xrange and range instead of the while constructs, and indeed, they are quite more elegant - but, after calculating the overhead (and losen flexibility) when working with range/xrange, and while loops, you get to the conclusion that it isn't really worth using range/xrange loops.
I'd like to show some examples and I'll be glad if someone can suggest some other fixes than while a loop :-) a) range overfllow : for i in range(0, 1 << len(S)) : ..... OverflowError: range() result has too many items ok, so we fix this one with xrange ! b) xrange long int overflow : for i in xrange(0, 1 << len(S)) : ........ OverflowError: long int too large to convert to int Next thing I miss is the flexibility as in C for loops : for (i = 0; some_function() /* or other condition */ ; i++) or, for (i = 0 ; i < 10 ; i++) i = 10; I don't think range/xrange sucks, but I really think there should be some other constructs to improve the looping flexibility. Other thing may be, that I just miss an equally elegant alternative that's why I'd like to hear some suggestions on how to fix the above issues.. (btw, I've already browsed the archives related to my issue,but i don't see any good solution) Thanks Jernej. -- http://mail.python.org/mailman/listinfo/python-list
