Say we have a Python function which enables a user to introduce themself, with parameters for first, middle, and last names:

def my_name_is(first, middle, last):
   print(f"Hello, my name is {first} {middle} {last}.")

Calling the function with appropriate positional arguments yields the expected introduction:

>>> my_name_is("Margaret", "Heafield", "Hamilton")
Hello, my name is Margaret Heafield Hamilton.

Since we're passing positional arguments to our function, the position of the arguments matters:

>>> my_name_is("Heafield", "Hamilton", "Margaret")
Hello, my name is Heafield Hamilton Margaret.

We could, instead, pass keyword arguments to the same function:

>>> my_name_is(first="Margaret", middle="Heafield", last="Hamilton"):
Hello, my name is Margaret Heafield Hamilton.

Since we are now passing keyword arguments to our function, the position of the arguments does not matter:

>>> my_name_is(middle="Heafield", last="Hamilton", first="Margaret")
Hello, my name is Margaret Heafield Hamilton.

More detailed information on keyword arguments can be found in the Python documentation.
