How to output an index while iterating over an array in python

Question

I am iterating over an array in python:

for g in [ games[0:4] ]:
    g.output()

Can I also initialise and increment an index in that for loop and pass it to g.output()?

such that g.output(2) results in:

Game 2 - ... stuff relating to the object `g` here.

for index, g in enumerate(games[0:4]):
    g.output(index)

Use the built-in enumerate method:

for i,a in enumerate(['cat', 'dog']):
   print '%s is %d' % (a, i)

# output:
# cat is 0
# dog is 1
