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.
