Yep, definitely a case of overdoing the list comprehensions when you
throw away the list.
I'll watch out for that in the future,

d.items() is not an iterator, you don´t need this. This code is
equivalent to l = d.items().

Hi everyone
Here is my problem:
I have a list that looks like this -
[['a', '13'], ['a', '3'], ['b', '6'], ['c', '12'], ['c', '15'], ['c',
'4'], ['d', '2'], ['e', '11'], ['e', '5'], ['e', '16'], ['e', '7']]
and I would like to end up with something like this, i.e. with the
only one list per letter
