Track 5 · Lesson 2 of 12

Parameters and arguments

Give functions inputs: declare parameters in the definition and pass arguments in the call, in the right order.

You will be able to

• Define a function with one or more parameters
• Pass arguments to a function and explain how they are matched to parameters by position
• Use parameters inside the body instead of fixed values or outside variables
• Recognise the TypeError raised when a call passes the wrong number of arguments
