Not really sure what issue is, I ran your code with no issues (Both on Python 3.4 and 3.7.1).dogresulted inbmewhen encrypting, and vice versa when decrypting. You should change yourwhileloop condition though, you are currently checking for0integer value but when user enters their choice it will be'0'as a string.

you're probably making a sum '+' operation with a string and an integer variable. Also try to be more clear and specific in your question and show what you have tried so far. You can add your code to your question and look for the line the error shows.
Adding this info here because i still don't have enough rep to comment.

The location of the closing parenthesis is wrong for ord in route of choice=='2'
Your code:
chr(ord(message[i] + 2))
Correct one:
chr(ord(message[i]) + 2)
You got the error because you do + operation before you cast character to integer.

Maybe you are missing close parenthesis. Your coderesult = result + chr(ord(message[i] + 2)has no closing parenthesis forchr.
