Why do you do a check like this:
if letter.isupper() == True:
It's wrong.
if letter.isupper():
It's correct.
Good luck.

Good. But could you explain why the minus sign is in front of the variable x? Thanks a lot.

A good solution, but is it necessary to check for other characters, because other characters can not be capitalized. Only letters can.

You just need to check the array without specifying the number of elements in it.
You can write like this:
def checkio(array):
return sum(array[::2]) * array[-1] if array else 0
# Another way to solve
# return len(array) and sum(array[::2] * array[-1])
Why that?

Why did you write like this?
...
elif n == 0:
return 1
...
When raising to the power of 0, the result is 1.

Yes, this solution is more difficult to understand, but if you think about it, everything becomes obvious.

This solution works, but you can do everything in one line and do not create unnecessary variables.
Like this:
def checkio(*args):
return abs(min(args) - max(args)) if args else 0
What you think about this solution?
