Keyword argument are also called named arguments. Variables in the function definition are used as keywords. When the function is called, you can explicitly mention the name and its value.
Example
By default, the function assigns the values to arguments in the order of appearance. In the second function call, we have assigned the value to a specific argument
It will produce the following output −
Name: Naveen Age 29 Name: miki Age 30
Let us try to understand more about keyword argument with the help of following function definition −
Since the values are assigned as per the position, the output is as follows −
num:10 den:5 quotient:2.0 num:5 den:10 quotient:0.5
Instead ofpassing the values with positional arguments, let us call the function with keyword arguments −
It will produce the following output −
num:10 den:5 quotient:2.0 num:10 den:5 quotient:2.0
When using keyword arguments, it is not necessary to follow the order of formal arguments in function definition.
Using keyword arguments is optional. You can use mixed calling. You can pass values to some arguments without keywords, and for others with keyword.
However, the positional arguments must be before the keyword arguments while using mixed calling.
Try to call the division() function with the following statement.
As the Positional argument cannot appear after keyword arguments, Python raises the following error message −
division(num=5, 10)
^
SyntaxError: positional argument follows keyword argument
