You can uninstall Python just as you would any other macOS application. While different versions of Python can safely coexist on a system in some cases, they do cause some confusion, so if you don't have a specific reason to maintain multiple versions, it's easiest to keep just one. Python 3.11.2 macOS 64-bit universal2 installerīefore you run this, it's not a bad idea to uninstall any other version you already have installed.As of this writing, the latest release of Python 3.11 is Python 3.11.2 macOS 64-bit universal2 installer, which is available at the following link. If you've taken previous coursework in Python, you may already have a version of Python installed on your machine, but it will be important that you use the right version in this course. Step 2: Downloading and installing Python Seriously! Do this! You'll be very glad you did as a programmer, filenames and their extensions are often relevant to the work you're doing, so it's important to see filenames as they are.
Make sure that Show all filename extensions is checked (i.e., we want this).Click Advanced to reveal the "advanced" settings. This pops up a dialog titled Finder Preferences.Under the Finder menu, select Preferences.This default is fine for casual users, but is certain to cause us problems in this course - and routinely causes problems for students in courses where there is programming involved - so everyone needs to turn this off, which is easy to do. When macOS displays its filenames, it can sometimes hide the "file name extension" (i.e., the part of the filename that follows the last dot), so that a file named alex.txt will simply have its name displayed as alex instead, with an icon used to visually differentiate one "type" of file from another. The first step is not to install a software package at all, but to be sure you've configured a macOS setting so that it's not set in a way that's fine for everyday users, but very troublesome for those of us who write programs or do other serious work.
