Should You Update Python? General Tips for Win/Mac/Linux

Generally, you can install as many Python versions as you want on your operating system, no matter if you run Windows, macOS, Linux, or Ubuntu. To access a specific minor version 3.x, you can run py -3.x in your terminal or shell.

For example, to run Python 2.6 and Python 3.9, both being installed in your system, you’d run:

py -2.6
py -3.9

On my Windows machine, for example, I first tried running Python 3.8 by using py -3.8 but it told me it didn’t find it. However, it found Python 3.9 and 3.10 so I ran py -3.9 which opened the Python shell. See here:

So, should you update your Python version?

In most cases, you don’t need to update your Python version by means of updating your PATH environment variables etc. It’s usually enough to just install a new version of Python alongside the old version.

Without further ado, here’s how you can update your Python installation on Windows:

How to Update Python in Windows?

To update your Python version on Windows, follow the steps as outlined next:

Step 1: Go to the official Python Windows Download page.

Step 2: Scroll down and download the latest stable release. In most cases, this will be “Windows Installer (64-bit)”.

Don’t expect a big red “Download” button here.

Step 3: Wait for the download to complete and double-click to run the installer.

Step 4: Python will automatically detect if you’re trying to upgrade to a new version and it’ll prompt you with the suggestion “Upgrade Now” which you should click.

Step 5: Wait for the installation to finish up and you’re done!

You can now run the new Python installation on your computer by typing python in your command line: the note at the top of the interactive shell will confirm that your new Python installation has been completed successfully.

If you have created virtual environments that depend on the old version, you can update the Python version in a specific virtual environment using the following command in your command line:

python -m venv ‐‐upgrade <PATH TO YOUR VENV>

How to Update Python in macOS?

To update or upgrade your Python installation on your macOS, follow these three steps:
