Answer 1

You can also only change input to int(input()) and delete x = i.lower() and change str(x) to i.

Answer 2

Sorry, I'm pretty new to Python and coding in general.. what string to I need to make an integer?

Answer 3

first line 5
should be x=i.lower()

than in if and elif statements
int(x) % 2 == 0

Answer 4

What do I need to change then?
