From the Python docs:
Operators in the same box group left to right (except for comparisons), including tests, which all have the same precedence and chain from left to right — see section Comparisons — and exponentiation, which groups from right to left).
So the ** operator(exponentiation) is right to left associative. For example,
2 ** 3 ** 4 will be evaluated as: (2 ** (3 ** 4))
For example,
print(2 ** 3 ** 0)
This will give the output:
2
