Rather than delete, just prioritize which one gets to use python. This answer isn't a direct response to OP, but as someone who had a similar question this is the functionality I was looking for when I was thinking of removing 2.7. The "python" Command On Unix-Like Systems The main barrier to a distribution switching the python command from python2 to python3 isn't breakage within the distribution, but instead breakage of private third party scripts developed by sysadmins and other users. I don't have any bash level scripts that call python2.7 with python so this change wouldn't be disruptive - while other systems would need their scripts adjusted accordingly if they did. This way, if Python2.7 is still needed, it can be called explicitly with python2.7 while simply calling python will default to Python3 because of the symbolic link. Sudo ln -s /usr/bin/python3 /usr/bin/python Since what I really wanted was to call Python3 with just python, I ran sudo rm /usr/bin/python We can confirm if the new version of Python is successfully installed or not by checking the Python version using the same above two commands.Came here in 2019 because I develop in Python3 by default and came to the same conclusion as OP after seeing what'd be removed after running apt purge python
#2 VERSIONS OF PYTHON ON MAC INSTALL#
We can download the installer and update or install the desired version using the Python installer. We can check the versions of Python 2 and Python 3 installed on Mac using the following commands.Īfter checking the version, the next step is to check if any new version is available on the official website. brew install Python Using Python Installer for macOSīefore updating or installing Python on Mac using the Python installer, the first step is to check the installed version of Python on Mac. Using the following command, we can also install Python 2 on macOS.
#2 VERSIONS OF PYTHON ON MAC CODE#
In case we have to use Python 2 to run a program, we can do so by indicating the default macOS Python binary path /usr/bin/python/ at the start of the code file, as shown below.
echo "alias python=/usr/local/bin/python3.7" > ~/.bashrc Therefore, we can use an alias that will point to the Python version installed by Homebrew to run the Python scripts. cp /usr/local/bin/python3 /usr/local/bin/pythonīut the problem with the above method is that it will be a problem to run some legacy code using Python 2 in the future. Never modify or delete files related to the pre-installed Python by Apple. If you use older versions of the Mac operating system but downloaded a new version of Python 3 from its official website, then you should be careful when trying to uninstall the program.

Once Python 3 is installed, we can set is as default to run the programs, using the following command. Please note, Apple pre-installed and provided Python 2.7 in Mac OS X 10.8. We can also update the Python 3 version from 3.x to 3.y using the following command on the terminal.
#2 VERSIONS OF PYTHON ON MAC HOW TO#
Once we have Homebrew, we can easily install Python on macOS using the following command on the terminal. Learn how to check your Python version in several different operating systems, including Windows, Linux, and MacOS, by following this updated tutorial. If Homebrew is not installed on your Mac, you can install it from here.
#2 VERSIONS OF PYTHON ON MAC SOFTWARE#
It helps in installing and updating the software through the terminal. Homebrew is an open-source package manager software for macOS and Linux.
And we can easily update Python on macOS using Homebrew.
Therefore another way to update Python to the latest version is by using a single command. When you download the app, follow these steps: Quit Python and all related processes. By far the simplest way to remove Python is with a little help from a third-party app. Homebrew names the executable python2 so that you can still run the system Python via the executable python. Besides, there’s a simple way to remove Python from your Mac without having to mess with commands. Because python2 is a keg, we need to update our PATH again, to point at our new installation: export PATH'/usr/local/opt/python2/libexec/bin:PATH'. We will also discuss how to install the latest version of Python 3 or Python 2 on Mac.Īlthough the easiest way to update or install the latest version of Python on Mac is by using Python’s official website, we will have to check for future updates manually by checking the site again and again. Now, we can install Python 2.7: brew install python2. In this tutorial, we will discuss different methods to update Python on Mac.
