Hi Everyone,I am relatively new to Python so please forgive me for what seems like a basic question. Assume that I have a list, a, composed of nested lists with string representations of integers, such that a = [['1', '2'], ['3'], ['4', '5', '6'], ['7', '8', '9', '0']] I would like to convert this to a similar list, b, where the values are represented by integers, such as b = [[1, 2], [3], [4, 5, 6], [7, 8, 9, 0]] I have unsuccessfully tried the following code: n = [] for k in a: n.append([int(v) for v in k]) print n Does anyone know what I am doing wrong? Thanks in advance. Samir -- http://mail.python.org/mailman/listinfo/python-list
You didn't tell us how it failed for you, so I can't guess what's wrong. However, your code works for me: >>> a = [['1', '2'], ['3'], ['4', '5', '6'], ['7', '8', '9', '0']] >>> n = [] >>> for k in a: ... n.append([int(v) for v in k]) ... >>> print n [[1, 2], [3], [4, 5, 6], [7, 8, 9, 0]] (Although you seem to have confused variables b and n.)
