Optional Arguments

The positional arguments are required to be filled in. However, you can assign a default value to the positional argument using the = operator:

In the example above, if you don't pass a value to the name argument, it will be assigned the default value "UnknownName". The default value "UnknownSurname" and the surname argument work similarly.

The default value makes the corresponding positional arguments optional, but the total number of positional arguments required to be passed remains strict.

In the next chapter, we will describe how to define a function that can take a variable number of arguments.
