Iterate a list with indexes in Python

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.
