    • You can define functions to provide the required functionality. Here are simple rules to define a function in Python:
      • Function blocks begin with the keyword def followed by the function name and parentheses (( )).
      • Any input parameters or arguments should be placed within these parentheses. You can also define parameters inside these parentheses.
      • The first statement of a function can be an optional statement - the documentation string of the function or docstring.
      • The code block within every function starts with a colon (:) and is indented.
      • The statement return [expression] exits a function, optionally passing back an expression to the caller. A return statement with no arguments is the same as return None.
