You do realize that you are throwing away the t that you created above?
And I'm pretty sure this loop is not doing what you think it is...
Lets try an experiment at the >?>> prompt:

 >>> for t,f in enumerate('testing'):
...    print t,f
...
0 t
1 e
2 s
3 t
4 i
5 n
6 g


Is that what you would have expected?

What is a?
