[RR Python] enumerate

enumerate(sequence, start=0)

Return an enumerate object. sequence must be a sequence, an iterator, or some other object which supports iteration. The next() method of the iterator returned by enumerate() returns a tuple containing a count (from start which defaults to 0) and the values obtained from iterating over sequence:

vault = "abcdefg"
print type(enumerate(vault))
print list(enumerate(vault))

for index, x in enumerate(vault):
    print index, x

 result:

<type 'enumerate'>
[(0, 'a'), (1, 'b'), (2, 'c'), (3, 'd'), (4, 'e'), (5, 'f'), (6, 'g')]
0 a
1 b
2 c
3 d
4 e
5 f
6 g
