@trashy_incel although you're right, the point "2000 is not the twentieth century." is still there.

Using prod from the math module solved it for me.

passed every test in Python, nonetheless not able to submit due to this error:

Traceback (most recent call last):
File "/workspace/default/tests.py", line 43, in
test.assert_equals(round(abs(geo_mean(list(arr), mean)), 5),
TypeError: bad operand type for abs(): 'NoneType'

try to beat my execution time ;)

Think this was the true intention of the kata.

Most readable solution imho. Nice

are you kidding me?

I heard that tuples are a little bit faster due to their immutability.

I like this sulution very much, the renaming makes it much more readable.

How the heck does this reversing work??

Good one :)

follow... great!
