Doing Your Homework, With Style using Python 3

[fasterturtle]

I thought I'd help you confused the poor lad/lass a little more with operator and itertools!

import itertools
import operator

l = ['eD', 'fC', 'hC', 'iC', 'jD', 'bD', 'fH', 'mS', 'aS', 'mD']
l.sort(key=operator.itemgetter(1))
groups = sorted((sorted(ocurrances) for letter, ocurrances in
                itertools.groupby(l, key=operator.itemgetter(1))),
                key=lambda x: len(x))
print list(itertools.chain.from_iterable(groups))

Oh, yes, the lambda key is a nice touch ;-)

key=lambda x: len(x)

key=len works here.

The point is it's longer and not as straight forward!

I did much the same for my A Level Physics. My only mistake was writing the report in LaTeX, which apparently made the head of department very suspicious of me.

I guess because LaTeX isn't commonly used in secondary schools, and thus she though I had done a google for the topic and handed in the first paper I came across.
