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:
[['a', ['13' '3']], ['b', '6'], ['c', ['12', '15', '4']], ['d', '2'],
['e', ['11', '5', '16', '7']]]
I have the feeling it's trivial, and I've scoured the group archives -
sets might be a possibility, but I'm not sure how to operate on a list
of lists with sets.
This function also gives me what I want, more or less, but I don't
know how to make it run until it's covered all the possibilities, if
that makes sense...
def sigh(list):
for a in list:
i = list.index(a)
if a != list[-1]: ##if a is not the last one, i.e. there is a
next one
n = alist[i+1]
if a[0] == n[0]:
a.append(n[1:])
del alist[i+1]
Sorry about the lengthy message and thanks for your suggestions - I'm
trying to learn...
