Question

I could swear I’ve seen the function (or method) that takes a list, like this [3, 7, 19] and makes it into iterable list of tuples, like so: [(0,3), (1,7), (2,19)] to use it instead of:

for i in range(len(name_of_list)):     name_of_list[i] = something 

but I can’t remember the name and googling ‘iterate list’ gets nothing.

Answer 1

>>> a = [3,4,5,6] >>> for i, val in enumerate(a): ...     print i, val ... 0 3 1 4 2 5 3 6 >>>
