How do I delete a letter from user input?

Question

I would like to make a palindrome. In order to do so I need to take the user input, subtract the last letter/number, reverse it, and put them together. I just can't figure out how to modify user input like that.

Answer 1

As input product is a string, you can slice it:

x = 'solo'
print(x[:-1])

>>>
sol

Answer 2

Slicing, I think you want it like this?
s = "abcd"
s = s[0:-1]
print(s)

The second line removes the last letter.
