What to Focus On

  • A function is organized and reusable code.
  • A function runs only when it is called.
  • Functions help avoid repetition.
  • Built-in functions are already available in Python.
  • No import is needed for built-in functions.
  • Each built-in function has a specific task.
  • int() converts values to integers.
  • float() converts values to floating-point numbers.
  • input() always returns a string.

Common Mistakes to Avoid

A function is only a named block of code, so it does not need to be called to do anything.

Parameters and arguments mean the same thing.

A function call can be written without parentheses if no arguments are needed.
