Getting Started with Python Programming

Getting Started with Python Programming

Last Updated : 23 Jul, 2025

Python is a versatile, interpreted programming language celebrated for its simplicity and readability. This guide will walk us through installing Python, running first program and exploring interactive coding—all essential steps for beginners.

Install Python

Before starting this Python course first, you need to install Python on your computer. Most systems come with Python pre-installed. To verify if Python is available on your computer, simply open command line interface (Command Prompt on Windows or Terminal on macOS/Linux) and type:

python --version

If Python is installed, this command will display its version but if it is not installed then to install Python on our computer, follow these steps:

python.org website Python Version

Step By Step Installation Guide:

That's it! Python should now be installed on your computer, and you're ready to start using Python.

Create and Run your First Python Program on Terminal

Once you have Python installed, you can run the program by following these steps:

  1. Open a text editor (e.g., Notepad on Windows, TextEdit on macOS, or any code editor like VS Code, PyCharm, etc.).
  2. Copy the code:- print('Hello World') above and paste it into the text editor.
  3. Save the file with .py extension (e.g., Hello.py).
  4. Open the terminal.
  5. Run the program by pressing Enter.
Python Script

You should see the output "Hello World" printed in the terminal.

Using Python’s Interactive Shell

For quick experiments, use Python’s interactive shell:

1. Launch the Shell:

python

or, if required:

python3

Python's Interactive Shell

2. Enter Commands Directly:

For example:

>>> print("Hello, World!")

Python Script on Shell

3. Exit the Shell:

exit()

Exiting the Shell Next Steps

With Python installed and your first script running, continue your journey by exploring:

Each step will help you build confidence and deepen your understanding of Python programming. While Learning Python, we will be using Geeksforgeeks code-editor present inside every tutorial, where you can learn and modify the code for practice. Let's see how to print Printing "Hello World" on online ide.

Using Python on Google Colab

Google Colab is a popular cloud-based platform that provides an interactive Python environment for running Python code. It’s especially useful for data science, machine learning, and educational purposes, as it allows you to write and execute Python code in the browser without installing anything locally.

Steps to Get Started on Google Colab:
  1. Open Google Colab: Go to Google Colab. You will need a Google account to access it.
  2. Create a New Notebook: After logging into your Google account, you can create a new notebook by selecting File > New Notebook. This will create a fresh Python environment where you can start coding.
  3. Running Python Code: In Colab, you can directly write Python code in cells and run them interactively. To run the code in a cell, click on the play button next to the cell or press Shift + Enter.

Example:
