Question

Write a function named middle that takes a string as an input and returns a string containing the middle character of the input if the length of input string is odd, or the two middle characters if the length is even.

Answer 1

To write a function that returns the middle character(s) of a string, you can follow these steps: Check the length of the input string. If the length is odd, return the middle character. If the length is even, return the two middle characters.

Step-by-step explanation:

To write a function that returns the middle character(s) of a string, you can follow these steps:

1. Check the length of the input string.
2. If the length is odd, return the middle character.
3. If the length is even, return the two middle characters.

Here's an example implementation in Python:

def middle(string):
length = len(string)
if length % 2 != 0:
return string[length // 2]
else:
return string[length // 2 - 1:length // 2 + 1]
