How to Install Python on Windows, macOS, and Linux - Full Tutorial

If you are looking to delve into the exciting world of Python, the first step is getting it installed on your computer. This comprehensive tutorial will guide you through the process of installing Python on Windows, macOS, and Linux - the three most popular operating systems in use today.

Before we begin

Let's take a moment to understand what Python is. Python is a high-level, interpreted programming language which is revered for its simplicity and readability. It is widely used for several applications ranging from web development to data analysis and machine learning.

Understanding Python Versions

Before installing Python, it's essential to understand that there are currently two supported versions of Python: 2.x and 3.x, with Python 3.x being the most current version. Though you can install both versions, we recommend Python 3.x as Python 2.x was deprecated in January 2020.

Python Installation on Windows

Start by navigating to the download page for Python at python.org. Select the Windows link. Choose the Python 3 installer applicable to your Windows: if your computer is running a 32-bit version, select 'x86' installer. If it's a 64-bit version, choose the 'x86-64' installer.

Run the downloaded .exe file. This will display the Python installer. We recommend ticking the box "Add Python 3.x to PATH" before selecting 'Install Now'. This action will set Python up in your system PATH, making it easily accessible from any command prompt.

After successful installation, verify it by opening the command prompt and typing 'python -v'. If properly installed, your command prompt should output the version of Python installed.

Python Installation on macOS

macOS often comes preinstalled with Python 2.x. However, this tutorial will guide you on how to install Python 3.x. Navigate to the Python downloads page and select the macOS link. Download the installer, open the downloaded .pkg file and follow the instructions.

After successful installation, open the terminal and type 'python3 -v'. It should return the version of Python installed.

Python Installation on Linux

Most Linux distributions come preinstalled with Python. To confirm, just type 'python --version' or 'python3 --version' in your terminal. If it’s not installed or you want to upgrade, follow these steps.

For Debian-based distributions like Ubuntu, use the following commands:

```

sudo apt-get update

sudo apt-get install python3.6

```

For Red Hat-based distributions like CentOS, use the following commands:

```

sudo yum update

sudo yum install python3

```

After successful installation, verify it by typing 'python3 -v'. This command should return the Python version installed.

Conclusion

With these steps, you should now have Python properly installed on your Windows, macOS, or Linux operating system. Happy coding!
