Question

assuming I have a dictionary like:

>>> dict = {}
>>> dict[123] = "test1"
>>> dict[456] = "test2"
>>> dict[789] = "test3"

and I loop through it like:

>>> for bit in dict.keys():
     print bit

how can I figure out which element is being processed? I would like to get an output of

0
1
2

How can I get this?

Please advise!
Thanks!

You could use enumerate():

d = {...}
for i, bit in enumerate(d):
    print i, bit

However, bear in mind that dict does not guarantee any particular ordering of its keys, so the indexes are probably not meaningful. There are other classes, such as collections.OrderedDict that do guarantee specific ordering of their keys, so you might need to use those.

Also, don’t call your variables dict as this shadows the builtin.
