TLDR: Don’t upgrade pre-installed Python 2.x to Python 3.x, it will probably break something by doing. TLDR: Do not upgrade Python 2.x to Python 3.x, just install Python 3.x on Mac Or you can also check out the extensive Python Wiki resource page here. MIT: Introduction to Computer Science course.You can also check out free online courses, including these from MIT: Automate boring stuff with Python: Practical programming for beginners.Python crash course: a hands-on, project-based demonstration of programming.If you enjoy learning about the book, the following are popular options (these are affiliate links to Amazon): If you are new to Python and programming in general, there are several good resources to get started. So now that Python 3 is installed, you’re ready to move on! Learning Python and Python resources Note that some aspects of Python are different in each version, and even features like a simple simple Python web server trick differ from version 2 to version If you plan to use something long-term or generally learn, it’s better to write in Python 3.x for older Python instead of x publications. You can also find out where each version of python is installed with the ‘what’ or ‘where’ command: In MacOS, you will typically find some variations of Python 2.7.x, either 2.7.4 or 2.7.10 or similar.Īfter installing Python using Homebrew or the package installer, you can check for an updated new version of Python in the following ways:Īnd as mentioned earlier, both Python installations exist without conflict. When you type the following command, Terminal tells you which version of Python is currently installed: How to check which version of Python is currently installed on Mac OS Whether you install an updated Python 3 package installer or Homebrew software, the default version of Python 2.7 preinstalled with Mac OS and Mac OS X will still be installed, completely intact, and can always be run with a simple python command. Once the updated Python 3 is installed on your Mac, you can use it in the following ways: To install the latest version of Python 3 using Homebrew, enter the following script: Of course, you need to install Homebrew on your Mac before you can use the Homebrew method, but if you’re interested in mixing with Python, Homebrew will probably please you anyway.Īssuming you already have Homebrew, if you don’t have one, you can read here how to install Homebrew on Mac OS. Installing an updated version of Python 3.8 (at the time of writing) is very easy with HomeBrew. You can also install Python 3.x on your Mac via Homebrew, which is the most popular way as a Homebrew user. You will also find a simple IDLE file called IDE in the / Applications / MacPython3 / directory, which will give you basically the same Python IDE that you would encounter if you ran ‘python3’ on the command line in Terminal. (The Modify option is then available on the drop-down menu.) You can also launch Visual Studio and the installer from the Windows Start menu by searching on "Visual Studio".Once Python 3 is installed, you will find the Python3 folder in the Mac / Applications directory. The Modify button changes to Update when updates to Visual Studio are available for any installed components. Also install the Desktop development with C++ workload for full C++ support.Īfter installation, the installer provides options to modify, launch, repair, or uninstall Visual Studio. Installs the C++ compiler and other necessary components to develop native extensions for Python. Installs tools for web development including HTML, CSS, and JavaScript editing support, along with templates for projects using the Bottle, Flask, and Django frameworks. Installs the Cookiecutter graphical UI to discover templates, input template options, and create projects and files. Also, if a newer version of Python is available than what's shown in the installer, you can install that version separately and Visual Studio will detect it. Visual Studio automatically detects existing Python installations. (You can return to the Visual Studio installer at any time to add or remove distributions.) Note: If you've installed a distribution outside of the Visual Studio installer, there's no need to check the equivalent option here. Anaconda, specifically, is an open data science platform that includes a wide range of pre-installed packages. Each includes the distribution's interpreter, runtime, and libraries. Choose any combination of the available options, such as 32-bit and 64-bit variants of the Python 2, Python 3, Miniconda, Anaconda2, and Anaconda3 distributions that you plan to work with.
