Python is a versatile and widely used programming language, and it is used for various tasks, from scripting to web development. Python, like many software, has different versions, and it’s important to know which version is installed on your system. 

This information is crucial because different Python versions may have variations in syntax or libraries, and ensuring you’re using the correct version is vital for compatibility with your projects. 

In this guide, we’ll explore various straightforward methods on how to check the Python version on your Linux, Windows, and Mac systems, giving you the confidence that you’re working with the right Python interpreter for your specific needs.

Check the Python Version on Linux

Linux is a popular platform for Python development and system administration. We can use the following methods to check the Python version on Linux systems like Ubuntu, Debian, Arch, etc. These methods can be used to find Python version:

  • Using the Command Line
  • Checking in the Interactive Shell
  • Using Package Managers
  • Checking the Path

Check Python Version Using the Command Line

The command line provides a straightforward way to get the Python version. Open your terminal and use this simple check Python version command:

For Python 2:

python --version

or

python -V

For Python 3:

python3 --version

or

python -V

Check Python Version Using Interactive Shell

Python’s interactive shell is another way to find Python version. Open your terminal and enter one of the following commands:

For Python 2:

python

For Python 3:

python3

Once you are in the Python interactive shell, you can get Python version with the following Python commands:

import sys
print(sys.version)

Check Python Version Using Package Managers

If you installed Python using a package manager, you can use these tools to check the Python version.

For Debian-based systems, such as Ubuntu, you can use `apt`:

apt show python3

For Red Hat-based systems, like CentOS, you can use yum:

yum info python3

NOTE: These commands will provide detailed information about the Python version installed on your system.

Finding Python Version by Checking the Path

You can also determine the path to the Python interpreter and indirectly obtain information about the installed version using the `which` command:

which python3

This command will return the path to the Python interpreter. You can then use this path to check the version:

/path/to/python --version

Replace ‘/path/to/python’ with the actual path obtained from the previous which command.

Check Python Version on Windows and Mac

Python is widely used on Windows and Mac for application development, data analysis, and more. To check the Python version on Windows or Mac system, you can follow these methods:

  • Using the Command Prompt/Terminal
  • Checking in the Interactive Shell

Finding the Python Version Using the Command Prompt/Terminal

Open the Command Prompt for Windows by searching for “cmd” in the Windows Start menu or open Terminal for Mac by searching Terminal in the MacOS spotlight search.  Then, use one of the following commands:

For Python 2:

python --version  
or
python -V

For Python 3:

python3 --version
or
python3 -V

These commands will display the Python version installed on your Windows/ Mac system.

Check the Python Version Using Interactive Shell

You can also find the Python version in the interactive shell. Open the Command Prompt/terminal and enter one of the following commands:

For Python 2:

python

the

python3

Once you are in the Python interactive shell, you can check the version with these Python commands:

import sys
print(sys.version)

This will display detailed information about your Python version.
