Python: Unpacking an inner nested tuple/list while still getting its index number -

i familiar using enumerate():

>>> seq_flat = ('a', 'b', 'c') >>> num, entry in enumerate(seq_flat):         print num, entry 0 1 b 2 c 

i want able same nested list:

>>> seq_nested = (('a', 'apple'), ('b', 'boat'), ('c', 'cat')) 

i can unpack with:

>>> letter, word in seq_nested:         print letter, word apple b boat c cat 

how should unpack following?

0 apple 1 b boat 2 c cat 

the way know use counter/incrementor, un-pythonic far know. there more elegant way it?

for i, (letter, word) in enumerate(seq_nested):   print i, letter, word
