Installing Python 3 on Mac OS X
Python 2 comes pre-installed on Mac OS X. However, you will need to install the newer Python 3 version to use this book. Even if you choose to stick with Python 2, you will still need to update the version that came pre-installed as it may be old.
Check what version of Python is installed
Open the Terminal (Open Applications folder, go the Utilities folder and double-click on the Terminal program.)
$ python –version and hit enter
You should get an output of: Python 2.7.14 (the version could be different)
Although Python for Mac OS is available from the Python Download page we would recommend that you use a package manager like Homebrew . Homebrew is a free package management system. It simplifies the installation of software on Apple’s Mac OS system.
|Homebrew requires Apple’s Xcode package be installed on your computer. Apple’s Xcode package is available for free download from the Apple Store.|
To install Homebrew:
Open and run Terminal and type:
|$ /usr/bin/ruby -e “$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)”|
Follow the prompts and install Homebrew.
Install Python 3, type:
|$ brew install python3|
Double check that it has been installed correctly:
|$ python3 –versionPython 3.6.3|
Open Applications folder, go the Utilities folder and double click on the Terminal program.
If you wish to exit, type:
or use the Control and D key at the same time.
