Python is a powerful, easy-to-learn programming language that is widely used for various applications, from web development to data science. This tutorial will guide you through the basics of Python, providing examples to help you get started.
Installing Python
To start coding in Python, you need to have Python installed on your machine. You can download Python from the official Python website.
Steps:
- Go to the Python downloads page.

Running Python Code
You can run Python code in several ways:
- Interactive Mode: Open a terminal or command prompt and type
python
(orpython3
on some systems). You can now type Python code directly, and it will execute immediately. - Script Mode: Write your code in a text file with a
.py
extension, then run the file by typingpython filename.py
in your terminal.
Basic Syntax
Let’s start with a simple “Hello, World!” program.

Save the above code in a file named hello.py
and run it using python hello.py
. You should see the output:
Hello, World!
