Sorting a tuple that contains tuples
hi
I have a list that goes A=[[a,'3'],[g,'1'],[y,2]]
I am looking for a quick way to arrange it according to the numbers (second dimension), so
NewA=[[g,'1'],[y,'2'],[a,'3']]
thanks
ariel

1The input/output is inconsistant, it is likely supposed to be the string '2' and not the int 2. – kevpie Dec 14 '10 at 17:36

from operator import itemgetter
newA = sorted(a, key=itemgetter(1))

1@a-a, the question's input/output is inconsistent, mixing strings and ints. – kevpie Dec 14 '10 at 17:38

@Kenny, @AA it returns the results, because `2` is an integer, and `1`, `3` are strings. It compares type names `str` and `int`. – khachik Dec 14 '10 at 17:40

@khachik: Right. It could be taken care by `sorted(a, key=lambda x:str(x[1]))`, but I don't think this is appropriate here. – kennytm Dec 14 '10 at 17:42
