Introduction
Python is a versatile scripting language that runs on most operating systems. As such, it is handy to know how to find out which version of Python you have, especially when working with teams on code compatibility. This article will show you a few ways to find out which version of Python you have.
Checking if Python is already installed
If you’ve got a Python project that’s been turned in to you, or you’re planning on checking out a project from GitHub, you’ll want to make sure that you’re using the same version of Python as the person who originally wrote it. This can be accomplished by checking if Python is already installed and, if so, what version is installed.
To check if Python is already installed, open the Command Prompt (✔️) and type “python.” If you see something like “Python 3.7.4” or “Python 2.7.16,” then Python is already installed on your computer! If you don’t see anything when you type “python” and hit enter, then Python isn’t currently set up correctly on your computer—but no worries! Follow the instructions below to get everything set up correctly.
Finding the version of Python you have installed
If you’re not sure which version of Python you have installed, there are a few ways to check.
1. On Windows, open the Command Prompt and type “python -V”. This will print out the version of Python you have.
2. On macOS, open the terminal and type “python -V”. This will print out the version of Python you have.
3. On Linux, open a terminal and type “python -V”. This will print out the version of Python you have.
If you don’t have Python installed, you can download it from python.org
Updating your version of Python
Python is a rapidly developing language. New features and bugfixes are released regularly. Therefore, it is important to keep your installation of Python up to date.
There are two ways to update your version of Python. The first is to manually download the latest release from the official Python website. The second is to use a package manager such as apt (deb), yum (rpm), or homebrew to install and update Python automatically.
To check which version of Python you have, run the following command:
python – version
If you need to update your version of Python, download the latest release from the official website and run the installer. After installation is complete, verify that the new version is selected as the default interpreter by running the following command:
What to do if you can’t find the version of Python you have installed
If you can’t find the version of Python you have installed, there are a few ways to check.
1. Check the default Python interpreter by typing “python” at the command line. This will print out the version number of the Python interpreter you are using.
2. If you have multiple Python interpreters installed, you can check their versions by typing “python -V” at the command line. This will print out the versions of all your installed Python interpreters.
3. You can also check the version of your Python interpreter by looking at its “about” page. For example, in IDLE, you can go to Help > About IDLE to see the version number of your installed Python interpreter.
Conclusion
If you need to know which version of Python you have, there are a few different ways to do it. You can always check the version by running Python -V from the command line. You can also check the version by looking for it in the output of the sys.version attribute. Finally, if you’re using an IDE like IDLE, you can check the version from within IDLE itself.
