help me make this code better please (basic)

[bntayfur]

It works fine if i give the right numbers
All the input must be between 0 and 100, it doesn't check that.

How do i make the code simpler? For example, in if elif else part is there a way to just give range? I tried to do it but i couldn't.

Help me improve this code pls
