Key Takeaways

To check the Python version on Windows, Mac, or Linux, type “python –version” into PowerShell on Windows, or the Terminal on Linux or Mac. To view the Python 3 version, run “Python3 –version” instead.

To check what version of Python is installed on your Windows, Mac, or Linux computer, all you have to do is run a single command. We’ll show you how to do that as well as what to do if you have multiple Python versions installed.

How to Read the Python Versions

A Python version consists of three values: a major version, a minor version, and a micro version. An example of a Python version is:

Python 3.10.4

In the above version, 3 refers to Python’s major version. The second digit, which is 10, refers to Python’s minor version, and the last digit, 4, indicates the micro version of Python.

Python’s major versions are generally not compatible with each other, but the minor ones are.

Check the Python Version on Windows

On your Windows PC where you’ve installed Python, use the PC’s built-in PowerShell utility to check the version number. You can also use Command Prompt if you want.

To start, open your “Start” menu and search for “PowerShell” (without quotes). Then click the utility in the search results.

python --version

The terminal will output your current Python version.

It is possible that you’ll get an error message if you don’t specify python3. If you do, just run the following alternative command:

python3 --version

What If Your Computer Has Multiple Python Versions Installed?

You could have multiple Python versions installed at the same time on your computer. This is because some apps use the newer Python 3 while others still rely on Python 2.7 in order to run. In this case, to find the version of each instance of Python, you’ll use the following commands.

To check Python 2.7’s version, use this command:

python --version

For Python 3, use the following command:

python3 --version

And you’re all set.

Wondering what version of PowerShell you’re running on your PC? It’s equally to find that information.
