when you use if nums

python check if the list at least have one element and return true

if list is empty python return false so automatically the if block is not excuted

I did the same but one-lined. In the other hand and IMHO it's not good practices create variables with names reserved by Python, even if there seems to be no risk.

oh right thank you

In python, empty lists and strings are falsy.

Very readable with the most obvious use of the math library.

ok thanks for the explanantion

Thank you for the information. I will look into this some more.

The error message is True should equal False and it means your function returned True when the expected value was False
