What to Focus On

  • Functions support modular programming.
  • A function is a named group of instructions for a specific task.
  • Functions make code easier to understand and reuse.
  • Function definitions begin with def.
  • The function header ends with a colon.
  • Indented statements form the function body.
  • Arguments are passed during function calls.
  • Parameters are written in the function header.
  • Default values are used when the call omits an argument.

Common Mistakes to Avoid

A function can be called before it is defined, as long as the definition appears later in the program.

Any parameter can have a default value, even if a non-default parameter comes after it.

A variable created inside a function can be used outside it after the function ends.
