Accessing the index in Python 39for39 loops

Questions

How do I access the index itself for a list like the following?

ints = [8, 23, 45, 12, 78]

When I loop through it using a for loop, how do I access the loop index, from 1 to 5 in this case?

Answers

Using an additional state variable, such as an index variable (which you would normally use in languages such as C or PHP), is considered non-pythonic.

for idx, val in enumerate(ints):
    print(idx, val)
