Exercise

Functions with one default argument

In the previous chapter, you've learned to define functions with more than one parameter and then calling those functions by passing the required number of arguments. In the last video, Hugo built on this idea by showing you how to define functions with default arguments. You will practice that skill in this exercise by writing a function that uses a default argument and then calling the function a couple of times.

Instructions

  • Complete the function header with the function name shout_echo. It accepts an argument word1 and a default argument echo with default value 1, in that order.
  • Use the * operator to concatenate echo copies of word1. Assign the result to echo_word.
  • Call shout_echo() with just the string, "Hey". Assign the result to no_echo.
  • Call shout_echo() with the string "Hey" and the value 5 for the default argument, echo. Assign the result to with_echo.
