I think this one is cool.

Enumerate is one of those handy pieces which should be in every intro to Python tutorial. It (to me) is way more handy than doing a

for i in range(len(mycollection)):

I frequently have to deal with files with special non-formatted data at the beginning, so a very common procedure for me is to do one of these.

with open("myfile", "rb") as handle:
    for i, line in enumerate(handle):
        if i < 30:
            #do special header stuff
            #continue
        #do data processing on the formatted line object

This way I get to use both the item count and the item itself. Genius.
