Course: Learn to build SaaS apps with Python Flask & Docker → For experienced programmers who want to learn Python. “ Python Programming” by Michael Dawson.Ģ. Absolute beginner with with programming a computer. If you’re in a learning mode, here are some good books:ġ. There is a boatload of friendly information about Python at their website. The IDLE edit window.Īlso, in the /Applications/Python3.6 folder is a file called ReadMe.rtf.
Here’s the start of some new code, partially written. Then, to get to the edit window in IDLE, go to the app’s menu bar, and select File > New. Documentation is found under the Help menu “IDLE Help.”įirst launch the IDLE app. If you don’t want to work on the command line, you can use this IDE to write and save your code. If, in the Finder, you go to /Applications/Python3.6, you’ll find the IDE called IDLE.app. Using the Basic IDE, Called IDLE, That Came With the Installation To get to the 2.7 version, you can, type on the command line: > pythonĦ. (You can see your default paths with > echo $PATH.) 5.

You don’t need to type the full path because it’s already in your shell’s path. The above points to: /Library/Frameworks/amework/Versions/3.6/bin/python3.6įinally, to run Python 3.6 interactively in the shell, type this on the command line: > python3.6 There will be a link to run the Python 3.6 executable here: /usr/local/bin/python3.6 Library/Frameworks/amework/Versions/3.6/
When the installer is finished, it will have installed Python 3.6 in this directory.

The install will take only a minute or so.

You’ll be asked for an administrator password because the macOS Library is written to. It will install on your boot drive by default, but you’ll be given a chance to change the install location. Walk through the installer by reading the package notes and agree to the license terms. When you double-click this file, it will launch the package’s installer, and you’ll see this: Python’s Installer Package Welcome That means everything from 10.6 Snow Leopard up to and including 10.13 Sierra.) (The 10.6 embedded in the file name means you need at least macOS Snow Leopard to run it. You’ll be downloading a macOS package file called “python-3.6.2-macosx10.6.pkg” to your downloads folder. You won’t have to delete any other version. If you’ve already downloaded a previous version of Python 3.x, the installer will create a new directory with new link called Python3.6. What do I Need to Know Before Installing? It’ll look like this: Python download page. You’re probably wanting 3.6.2 (as of August 2017). It should auto-detect that you’re on a Mac. Go to the Python website’s download page. It’s particularly easy to do because 1) There’s an macOS installer package that does all the work and 2) it includes a basic IDE, and 3) you can still run both versions, so there’s no penalty to installing 3.6.x. Secondly, if you want to use a specific third party package or utility that doesn’t yet have a released version that is compatible with Python 3, and porting that package is a non-trivial task, you may choose to use Python 2.7 in order to retain access to that package.Īlternatively, if you’re a newbie to the language and/or your class instructor insists that you begin by learning 3.x, then you’ll need to install it on your Mac. In the past, the site said:įirstly, if you’re deploying to an environment you don’t control, that may impose a specific version, rather than allowing you a free selection from the available versions.

So should you ever be using 2.7? Not unless you absolutely have to and accept that you’ll have to rewrite your code at some point. Python 2 will reach end of life (EOL) in the year 2020.
As a result, the 3.x version can’t be depended on to run 2.x scripts. To do this, backwards compatibility had to be compromised. Even macOS 10.13 High Sierra has Python 2.7.4 as its only version.Īs the Python website says, “ Python 2.x is legacy, Python 3.x is the present and future of the language.” Briefly, in order to move forward technically as a language, the creator, Guido van Rossum, needed to make some significant internal changes. Python 2.x is installed in macOS by default.
