i am using multidimention list in my python application. i need to sort it on column bassis.

here is my list example

list = [
['a','b',2,3,5],
['a','b',5,6,5],
['a','b',2,2,7],
['a','b',8,7,1],
]
suppose i want to sort it on column 3 (i.e. index=2).
i have tried
list.sort(key = lambda x:x[2])
it works in python ide, but sows error in mobile emulator that "typeerror: sort() takes no keyword argument"

i tried another option of

from operator import itemgetter
list.sort(key=itemgetter(2))

it also works in python ide , but in mobile emulator "type error: itemgetter is not defined"

any idea to this problm ?
please help as soon as possible...

Google "python DSU". Or try this (copy/paste to python shell):

def dsu_sort(list, index):
  newlist = [ (item[index], item) for item in list ]
  newlist.sort()
  list[:] = [ item for (name, item) in newlist ]

list = [
['a','a',2,3,5],
['x','a',5,6,5],
['e','d',2,2,7],
['g','f',8,7,1],
]
dsu_sort(list,4)
print list # now sorted by last column
