As AlbaClause had demonstrated you can iterate over indices as well
using the for-statement and the range() function. But you can also
combine iterating over elements and indices at the same time using the
builtin enumerate() type:

for i, item in enumerate(("s1","s2")):
    print i,item

0  s1
1  s2
