Python3 on Mac

Mac by default does not ship with Python 3 this means you have to install it manually.

There are many ways of installing it, the first way is to download the pre-build package from the official website and installing it on your system.

The second way is by compiling it on your system.

While both the way listed above are the correct way to install Python3 updating to the latest version might a bit of a work because the above methods don’t update by themselves or with a help of any command line tools.

The third way is to install it with the help of Homebrew

Homebrew is a package for Mac that lets you install any package a viable in its repository with less that 4 commands depending on the install instructions.

If you have Homebrew already installed on your system you are good to go, if not you can install it from here

Python3 can be installed by entering this simple command in terminal.

brew install python3  

Linking Python3 apps and utilities by entering this command

brew linkapps python3  

You can update to the latest version of Python 3 by entering this command

brew upgrade python3  

Now you are good to go with your Python3 based development environment on your Mac

Happy Coding!
