kwargs Parameters in Python
In this lesson, you will learn about kwargs parameters or arguments in python, its syntax with some examples.
Arguments in Python
Arguments or parameters are values passed to a function inside the parenthesis. A function can have multiple arguments in it, separated by a comma.
We can use special symbols to pass multiple arguments to a function. There are two special symbols:
- *args (Non-Keyword Arguments)
- **kwargs (Keyword Arguments)
In this lesson, we are going to see about the non-keyword arguments in python.
kwargs Parameters in Python
**kwargs parameters or arguments are keyword length arguments in python. As we know that a function in python can have an infinite number of arguments for a function, it is important to declare them all. If you are not sure about the number of keyword length arguments, you can use the (*). So when you are not sure about the number of keyword arguments, you can use (*kwargs). This will pass the arguments through the function and will return the result.
Syntax:
def keyword_parameter(**kwargs): statements
Let’s understand more about the **kwargs with the help of a program.
Sample program using the **kwargs in python program
Input:
[gamipress_button label=”Try It” onclick=”window.open(‘https://coderseditor.com/?id=1401′,’_blank’)”]
def kwarg_parameters(**names):
print("Welcome to " + names["fname"]+'\t' +names['lname'])
kwarg_parameters(fname = "Developer Publish Academy!", lname = "Have a Good Day!")
Output:
Welcome to Developer Publish Academy! Have a Good Day!
