A Step-by-Step Guide to Installing Python on Your System

how to install python

Python is a versatile and widely-used programming language known for its simplicity and readability. Whether you’re a beginner or an experienced developer, having Python installed on your system is essential for creating a wide range of applications, from web development to data analysis and more. In this article, we’ll walk you through the process of installing Python on your computer.

Choose Your Python Version

Before you start the installation process, it’s crucial to decide which version of Python you want to install. As of writing, there are two main versions: Python 2 and Python 3. However, Python 2 is no longer actively supported, so it’s recommended to go with the latest version of Python 3.

Download the Python Installer

To install Python, you’ll need to download the official installer from the Python Software Foundation’s website (python.org). On the website’s Downloads section, you’ll find installers for various operating systems, including Windows, macOS, and Linux. Make sure to choose the installer that matches your operating system and the version of Python you’ve selected.

Run the Installer

Once the installer is downloaded, locate the file and run it. On Windows, you’ll likely need to double-click the downloaded executable file. On macOS and Linux, you might need to open a terminal window, navigate to the directory containing the installer, and then execute it from the command line.

Customise the Installation (Optional)

The installer might provide you with some customization options. For beginners, the default settings are usually sufficient. However, if you’re more experienced, you can choose to customise the installation location, add Python to your system’s PATH, or install additional components.

Add Python to PATH (Recommended)

Adding Python to your system’s PATH makes it easier to run Python scripts from the command line. This step is particularly important if you plan to use Python for development regularly. Most installers provide an option to add Python to PATH during installation, but if you skipped that step, you can typically modify it later through your system settings.

Verify the Installation

Once the installation is complete, it’s a good practice to verify that Python has been installed correctly. Open a terminal (or Command Prompt on Windows) and type `python –version` or `python3 –version`, depending on your system. This command should display the version of Python you’ve installed.

Install a Code Editor or IDE (Optional)

While you can write and run Python code in a simple text editor, using a code editor or integrated development environment (IDE) can enhance your development experience. Popular choices include Visual Studio Code, PyCharm, and Jupyter Notebook. These tools offer features like syntax highlighting, debugging, and project management.

Install Package Manager (pip)

Python’s package manager, pip, makes it easy to install third-party libraries and packages. It usually comes pre-installed with Python, but if it’s not, you can install it separately. Open a terminal and enter the command `python -m ensurepip` or `python3 -m ensurepip` to install pip.

Install Packages

With pip installed, you can start installing packages using the command `pip install package-name`. Replace `package-name` with the name of the package you want to install. For example, to install the popular NumPy library for numerical computing, you’d use the command `pip install numpy`.

Keep Python Updated

Python is actively developed, and updates are released periodically to improve performance, fix bugs, and introduce new features. It’s a good habit to keep your Python installation up to date. You can use the command `pip install –upgrade python` to upgrade to the latest version of Python.


Is Python free to install?

If you would like to download and install Python on your computer you can do it for free at python.org.

Where to install Python?

By default the Python installer for Windows places its executables in the user’s AppData directory, so that it doesn’t require administrative permissions. If you’re the only user on the system, you might want to place Python in a higher-level directory (e.g. C:\Python3. 7 ) to make it easier to find.


Installing Python on your system is a straightforward process that opens the doors to a world of programming possibilities. By following these steps, you’ll have Python up and running in no time. Remember to choose the right version, verify the installation, and explore the wealth of packages and tools available to make your Python development journey a smooth and productive one.
