Antlr4 Under Python3 Install The Python

Modern versions of Mac OS support Python 2.7.x (or Python 2.6.1 in older versions), but many users need to upgrade to Python 3.6 or 3.7.

Antlr4 Under Python3 Install The Python

Today I will explain how to install the Python 3 update on a Mac in two different ways.

Note that I mean install update rather than upgrade, since Python 2 will remain on the Mac with this method.

Some Mac programs require Python 2, and when upgrading they may start to malfunction or stop working altogether.

Therefore, we will not update the installed version, but install Python 3 in parallel.

Python 3 and Python 2 can coexist on the same Mac without conflicts, just the commands will differ slightly.

How to install Python 3 in macOS with Installer The easiest way is to download the Python installer from the python.org website.

Python 3.6.x requires about 100MB of available disk space.

The installation process is very fast; When Python 3 is installed, you will see the Python3 folder in Applications on your Mac.

Next method will show you how to install Python 3.x on a Mac through Homebrew.

How to install Python 3 using Homebrew Installing an updated version of Python 3 through Homebrew is extremely simple.

Of course, Homebrew should be installed on your computer, however, if you are interested in this method, then you probably have already used the program more than once.

This script installs Homebrew to usrlocal so that you dont need sudo when you brew install.

It is a careful script; it can be run even if you have stuff installed to usrlocal already.

Now to install Python 3 via Homebrew, run the following command in Terminal: brew install python3 When Python 3 is installed on a Mac, you can start the program with: python3 In any case, after installing Python 3 on a computer, the version of Python 2.7 will still remain on it, and you will be able to use it.

How to Find out the Installed Version of Python Open the Terminal program and use the following command: python --version In most cases, Python 2.7.x will be installed on macOS: either 2.7.4 or 2.7.10.

Note: Once again, I want to remind you that you do not need to upgrade Python 2.x to Python 3.x, because this can lead to program malfunctions.
