Debug the code yourself on each iteration print out the value individually and you may spot were the error is emerging from

Maybe you need to parse the input from string to a number?

The ord() function expects just 1 character. You're giving it multiple characters...

Try converting each character in the string one by one.

Expected a character. That should tell you the problem, the function accepts a single character.

Ord only accepts one character.
Hmm
