Question

I would need to use the map function in Python(2.4.4) to add 1 to each item in the list, so I tried converting the strings into integers.

line=[['10', '13\n'], ['3', '4\n'], ['5', '3\n'], ['1', '13']]

map(lambda X:(X+1),int(line))

Is this not working because of \n and the nests?

Answer 1

Well your intent is not clear but it is not due to \n.

See :

>>> line=[['10', '13\n'], ['3', '4\n'], ['5', '3\n'], ['1', '13']]
>>> map(lambda X:([int(X[0])+1, int(X[1]) +1]),line)
[[11, 14], [4, 5], [6, 4], [2, 14]]
