for-loop with index in Python

Everyday something new to learn For quite some time now I'm coding mostly small scripts but also bigger stuff in Python (and now I'm also trying to get really into Django) and from time to time Python's for-each preference to the C-style for loops sometimes got a little bit in my way.

For example: I have a list and I want to iterate over it but also know where I am during this loop. So until today I would have gone this road:

data = ('a','b','c')
   i = 0
   for f in data:
       print "%d => %s"%(i,f)
       i+=1
