Python for loops giving error

[perfringo]

Is the code you provided intended correctly?

It suspect that problem is that you overwriting combination value with every loop iteration and therefore you get only last result.

>>> combinations = list()
>>> for i in range(3):
...     combinations.append([1, 2, 3])
...
>>> combinations
[[1, 2, 3], [1, 2, 3], [1, 2, 3]]
>>> for row in combinations:
...     print(sequence_product(row))
...
