[Baypiggies] python list manipulation using map

[Vikram K]

i have a list whose elements are strings. all the elements in the list are
numbers but are represented as string type and i wish to convert them to int
type. i tried using map but the output is not what i want. please help.

 x = ['0', '0', '20', '15', '42', '0', '0', '0', '0', '0', '0', '0', '0',
'52', '57', '0', '254', '0', '177', '0', '617', '1021979']

>>> T2 = [map(int, i) for i in x]
>>> T2
[[0], [0], [2, 0], [1, 5], [4, 2], [0], [0], [0], [0], [0], [0], [0], [0],
[5, 2], [5, 7], [0], [2, 5, 4], [0], [1, 7, 7], [0], [6, 1, 7], [1, 0, 2, 1,
9, 7, 9]]
