Explanation
  1. There should be a colon (:) at the end of the function definition line to indicate the start of the function block.
  2. Python's built-in function for generating sequences is range(), not Range().
  3. Python keywords like return should be in lowercase.
  4. When calling a function in python, the arguments passed to the function should be enclosed inside parentheses () not square brackets [].
