What is python?
Python is a high-level, interpreted programming language known for its simplicity, readability, and versatility. It is used for a wide range of applications such as web development, scientific computing, data analysis, artificial intelligence, and more. Python supports multiple programming paradigms including object-oriented, functional, and procedural.
First Program in Python
Here’s how you can write a “Hello, World!” program in Python:
print("Hello, World!")Save this code in a file with a .py extension, for example hello_world.py, then run it using the Python interpreter.
The code print(“Hello, World!”) contains a string “Hello, World!”. In Python, a string is a sequence of characters enclosed in either single quotes (‘) or double quotes (“).
print is a built-in function in Python that outputs a string or any other object to the console or terminal. The print function takes one or more arguments and displays them on the screen. In the example print(“Hello, World!”), the string “Hello, World!” is passed as an argument to the print function, causing the message “Hello, World!” to be displayed on the screen.
Advantages and Disadvantages of Python Language
