Now it’s time to discuss the main topic of this blog, that is, how to upgrade Python to 3.9. Here, we will discuss upgrading Python to 3.9 on all popular operating systems like Linux, Windows, and macOS.

Upgrade Python to 3.9 on Operating Systems

To install Python on your popular operating systems like Linux, Windows, and macOS, you need the greatest tool for installing and managing Python packages is PIP. The many apps that make use of Pip contribute to its popularity. Pip allows third-party packages to handle binary packages using the easy set-up package manager. Since piping is now a standard feature in Python’s most recent releases, this article will provide detailed instructions on installing PIP and updating Python.

First, you need to understand what PIP is.

What is PIP?

PIP is a framework for managing and installing Python-written software packages. The phrase “preferred software installer” or “Pip Installs Packages” describes it. A command-line interface called PIP is used for Python to handle PyPI program installation. You might need to upgrade PIP if you’re using Python on Windows in an older version. To quickly run PIP on Windows, download the program file, launch the command line, and launch the installer. You will learn how to install PIP on Windows, modify it, update it, and configure it.

Let’s begin with how to upgrade Python version 3.9 to Windows.

Update Python to 3.9 on Windows

Follow the following steps to update Python on Windows-

    • Use installer to upgrade to 3.9
    • Visit the Python Releases for Windows section of the official Python website in your browser.
    • To download the installation file to your computer, click the Download Python button.
    • After that, launch the Python installer. The installer recommends installing Python 3.9 if upgrading from another version of Python 3 (for example, 3.8.10). Select Customize Installation to choose the install location and features, or choose Install Now to install Python with suggested options.
    • The installer will offer to upgrade your Python installation if you currently have an older version of the same Python release (for instance, 3.9.1). Continue by choosing Upgrade Now.
    • Check to see if the new version of Python was successfully installed after the installation is complete. Start Windows PowerShell and enter:
  • python3 –version
  • The most recent iteration of Python should appear in the output.

Utilize the Microsoft Store to Download Python 3.9.

Find and download the Python 3.9 app from the Microsoft Store if you want to use it to test out some basic ideas or learn the fundamentals of the language.

    3. To begin the installation, click the Get button.
    4. Find the program on the Start Menu to begin the interactive Python 3.9 experience.

Now it’s time to see the upgradation process of Python to 3.9 on Linux.

Update Python to 3.9 on Linux

Follow the following steps to update Python to 3.9 on Linux.

  1. Update the repositories first:

sudo apt update

  1. Install Python 3.9 next by executing:

sudo apt install python3.9

Type Y to begin the installation when prompted.

  1. After installing Python, launch the 3.9 version by typing:

Python 3.9

  1. The old version is still returned when using the python —version command to verify the installation. You must compile a list of update options to correct this. First, use the command to add the previous version to the list:

sudo update-alternatives –install /usr/bin/python3 python3 /usr/bin/python3.[old-version] 1

  1. Add the updated version now:

sudo update-alternatives –install /usr/bin/python3 python3 /usr/bin/python3.9 2

  1. Next, enter the command shown below to modify the versions’ priority status:

sudo update-alternatives –config python3

The output lists the options and their corresponding integers (in the example below, the numbers are 0, 1, and 2). Press Enter after entering the version number that you want to use.

  1. Remove the symlink that contains the previous Python 3 version if you don’t intend to use the old version of Python.

sudo rm /usr/bin/python3

  1. Then, substitute the old version for the symlink:

sudo ln -s python3.9 /usr/bin/python3

  1. Check the current default version:

python3 –version

The output should attest to the latest version’s successful installation and configuration.

Update Python to 3.9 on macOS

Similar to how you updated Python on Windows OS, you may obtain the most recent version of Python for macOS from the official Python website. You can use the commands mentioned below to check the Python version to see if it has been updated to the most recent version.

$ python –version

Python 2.x.x
