python all possible combinations of 0,1 of length k [duplicate]

by

itertools.product() takes a repeat keyword argument; set it to k:

product(range(2), repeat=k)

Demo:

>>> from itertools import product
>>> for k in range(2, 5):
...     print list(product(range(2), repeat=k))
... 
[(0, 0), (0, 1), (1, 0), (1, 1)]
[(0, 0, 0), (0, 0, 1), (0, 1, 0), (0, 1, 1), (1, 0, 0), (1, 0, 1), (1, 1, 0), (1, 1, 1)]
[(0, 0, 0, 0), (0, 0, 0, 1), (0, 0, 1, 0), (0, 0, 1, 1), (0, 1, 0, 0), (0, 1, 0, 1), (0, 1, 1, 0), (0, 1, 1, 1), (1, 0, 0, 0), (1, 0, 0, 1), (1, 0, 1, 0), (1, 0, 1, 1), (1, 1, 0, 0), (1, 1, 0, 1), (1, 1, 1, 0), (1, 1, 1, 1)]
