how can i print all sequences of given length using only 'O' or 'Z' in python?

Question

How can I print all sequences of a given length using only 'O' or 'Z' in Python?

For example, if I give length = 3

the output would be:

'OOO'
'OOZ'
'OZO'
'OZZ'
'ZOO'
'ZZO'
'ZOZ'
'ZZZ'

You can achieve this by generating the cartesian product of the elements using itertools:

import itertools

letters = ["O", "Z"]
length = 3

vals = [''.join(comb) for comb in itertools.product(letters, repeat=length)]

print(vals)
>>>['OOO', 'OOZ', 'OZO', 'OZZ', 'ZOO', 'ZOZ', 'ZZO', 'ZZZ']
