Question

Write a Python program that taks a word as an input, and output a word (string) based on the input.

  • If the input string already ends with "er", then add "est" instead, regardless of the length of the input string
  • If the input string already ends with "est", then your program should output the same input string as an output.
  • If the input string does not end with "er" or "est":
    1. If the length of the input string is less than 4, then your program should output the same string as an output.
    2. If the input string’s length is greater than or equal to 4, then your program should add "er" at the end of the input string.
  • #todo
    #assign the result string to variable "out_str"
    def task4(in_str):
      # YOUR CODE HERE
        
        return out_str
