In Python, how can I generate a string with all combinations of a set of characters up to a certain length?
I know how to use itertools to generate all combinations and permutations, but I can't figure out how to generate strings of dynamic length.
For example:
a = [0,1] length = 4
Result:
[0000, 0001, 0010, 0011, 0100, 0101, 0110, 0111, 1000, 1001, 1101, 1110, 1111]
You could use itertools.product
:
li = []
for i in itertools.product([0,1], repeat=4):
li.append(''.join(map(str, i)))
print (li)
>>> li
['0000', '0001', '0010', '0011', '0100', '0101', '0110', '0111', '1000', '1001', '1010', '1011', '1100', '1101', '1110', '1111']
Possible one liner:
[''.join(map(str, i)) for i in itertools.product([0,1], repeat=4)]
