Why Python?

Before we dive into how to set up Python on Windows, let’s take a quick look at why Python is so popular. Python is a high-level programming language that is easy to learn and read. It has a simple and clear syntax that makes it an excellent language for beginners. Python is also highly versatile and can be used for a wide range of applications, from web development to scientific computing.

Python has an active community that has developed a vast number of libraries and tools, making it easy to accomplish tasks. It is an open-source language, which means it is free to use and distribute. Python’s popularity has soared in recent years due to its use in data science and artificial intelligence, making it a valuable skill to have in today’s job market.

Downloading Python

The first step in setting up Python on your Windows system is to download the latest version of Python. You can download Python from the official website ( Python is available in two versions, Python 2 and Python 3. It is recommended to use Python 3 as it is the most recent version.

When you visit the official website, you will see two options for download. You can either download the executable installer or the source code. The executable installer is the easiest and most convenient option for most users. Click on the "Download Windows x86-64 executable installer" button to download the installer.

Installing Python

After downloading the Python installer, locate the downloaded file and double-click to run it. You will see a setup wizard that will guide you through the installation process. Follow the prompts and accept the default options unless you have a specific reason to change them.

One of the prompts will ask you to select the installation directory. The default installation directory is usually fine, but you can choose a different directory if you prefer. Once you have selected the installation directory, click the "Install" button to begin the installation process.

Adding Python to PATH

After installing Python, you need to add it to the PATH environment variable. The PATH environment variable is a list of directories that the operating system uses to search for executable files. Adding Python to PATH allows you to run Python scripts from any directory without having to specify the full path to the Python executable.

To add Python to PATH, follow these steps:

  1. Press the Windows key and type "environment variables" in the search bar. Click on "Edit the system environment variables."
  2. Click on the "Environment Variables" button at the bottom of the System Properties window.
  3. Under "System Variables," scroll down and find the "Path" variable. Select it and click the "Edit" button.
  4. Click the "New" button and add the path to the "Scripts" folder in the Python installation directory. The path should look something like "C:Python38Scripts" (replace "Python38" with your Python version).
  5. Click "OK" to close all the windows.

Testing Python

After adding Python to PATH, you can test whether it is working correctly by opening a command prompt and typing "python" in the terminal. If Python is installed correctly, you should see something like this:

Python 3.8.3 (tags/v3.8.3:6f8c832, May 13 2020, 22:37:02) [MSC v.1925 64 bit (AMD64)] on win32
Type "help", "copyright", "credits" or "license" for more information.

This means that Python is working correctly, and you can start using it.

Installing Python libraries

Python libraries are pre-written code that you can use to accomplish specific tasks. Installing Python libraries is easy using the pip package manager, which comes with Python.

To install a Python library, open a command prompt and type the following command:

pip install library_name

Replace "library_name" with the name of the library you want to install. For example, to install the NumPy library, type "pip install numpy" in the command prompt.

Using an Integrated Development Environment (IDE)

An Integrated Development Environment (IDE) is a software application that provides a comprehensive environment for developing software. IDEs offer features such as code highlighting, autocompletion, and debugging, making it easier to write and test code.

There are several IDEs available for Python, including PyCharm, Visual Studio Code, and Spyder. PyCharm is a popular IDE that is specifically designed for Python. Visual Studio Code is a lightweight IDE that supports multiple programming languages. Spyder is an IDE that is similar to MATLAB and is popular among data scientists.


In conclusion, setting up Python on Windows is a straightforward process. Download the latest version of Python from the official website, run the installer, and add Python to PATH. You can then start using Python to write code and install libraries to accomplish specific tasks. Using an IDE can make it easier to develop software, but it is not necessary. Python is a powerful language that is easy to learn and has many applications, making it a valuable skill to have.
