Python Function Arguments: Overview of Parameters and Arguments

First of all, let`s learn what positional, keyword, and optional arguments are.


python

The example above uses positional arguments. If you pass a different number of arguments, an error will occur. To call the function add(1, 2, 3), you just pass the arguments by their positions. The positional argument is a mandatory one.


python

Also, you can pass arguments using names. And there are keyword arguments. In this case, you do not need to follow the order of the arguments.


              1234
            
def add(a, b, c = 0):
    return a + b + c
print(add(1, 2))
print(add(1, 2, 3))

After giving a default value to the argument, it becomes an optional one. So, you may pass it, and if not, the function will use the default value.
