Before doing any tests with Python, I want to upgrade the Python engine to the latest version on my macOS system.

1. Go to Python download Website at

2. Click "Download Python 3.8.0" button. And save the download file.

3. Double-click on the download file "python-3.8.0-macosx10.9.pkg" and follow installation instructions to finish the installation.

4. Go to the Launchpad. You see 2 new applications: Python IDLE and Python Launcher.

There are a number of ways to use the newer version of Python:

Note that the newer version of Python did not replace the older version. So you have two versions of Python on your macOS located at different directories.

Python 2.7 Version - This is the older version pre-installed in the macOS system. You can access Python 2.7 with the "python" command:

herong$ python --version
Python 2.7.10

herong$ which python

Python 3.8 Version - This is the newer version installed by you. You can access Python 3.8 with the "python3" command:

herong$ python3 --version
Python 3.8.0

herong$ which python3

herong$ ls -l /usr/local/bin/python3
... /usr/local/bin/python3 -> \
