Args in Python | Python Tutorial in Urdu and Hindi | Python Tutorials for Beginners | Ali Code

In Python, *args and **kwargs are special syntaxes used in function definitions to pass a variable number of arguments to a function1.

*args is used to pass a non-keyworded, variable-length argument list1. The syntax is to use the symbol * to take in a variable number of arguments1. Here’s an example:
def myFun(*argv):
for arg in argv:
print(arg)

myFun('Hello', 'Welcome', 'to', 'Ali Code')
Copy
Output:

Hello
Welcome
to
Ali Code

**kwargs is used to pass a keyworded, variable-length argument list1. We use the name kwargs with the double star. The reason is that the double star allows us to pass through keyword arguments (and any number of them)1. Here’s an example:
def myFun(**kwargs):
for key, value in kwargs.items():
print ("%s == %s" %(key, value))

myFun(first ='Geeks', mid ='for', last='Geeks')
Output:

first == Geeks
mid == for
last == Geeks

These special symbols used for passing arguments are very useful when we are unsure about the number of arguments we should pass in a function1.

Python is a high-level, general-purpose programming language1. It was designed by Guido van Rossum and first released in 19911. Python’s design philosophy emphasizes code readability with the use of significant indentation1. It is dynamically typed and garbage-collected1.

Python supports multiple programming paradigms, including structured (particularly procedural), object-oriented, and functional programming1. It is often described as a “batteries included” language due to its comprehensive standard library1.

Python can be used for a variety of applications such as web development (server-side), software development, mathematics, and system scripting2. It can be used on a server to create web applications, alongside software to create workflows, connect to database systems, read and modify files, handle big data, and perform complex mathematics2.

Python works on different platforms (Windows, Mac, Linux, Raspberry Pi, etc.) and has a simple syntax similar to the English language2. Python runs on an interpreter system, meaning that code can be executed as soon as it is written. This means that prototyping can be very quick2. Python can be treated in a procedural way, an object-oriented way or a functional way2.
