Count indexes using “for” in Python

Question

I need to do in Python the same as:

for (i = 0; i < 5; i++) {cout << i;} 

but I don\'t know how to use FOR in Python to get the index

Answer 1

use enumerate:

>>> l = ['a', 'b', 'c', 'd']
>>> for index, val in enumerate(l):
...    print "%d: %s" % (index, val)
... 
0: a
1: b
2: c
3: d
