Adding a keyword argument

Keyword arguments are particularly useful in text processing functions because they allow you to specify optional transformations while keeping the function call readable. By using default arguments, you can define the most common behavior (like converting to lowercase) while still allowing users to override it when needed.

In this exercise, you will create a clean_text() function that replaces spaces with underscores and optionally converts text to lowercase.

  • Define the clean_text() function with parameters text and lower (with a default value of True).
  • Inside the else block, apply the lowercase transformation.
  • Call the clean_text() function with product as the argument to test the default behavior.
