If you do something a little more useful and run a script with the Python 3 interpreter, follow the python3 command with the path to your.

This allows you to type Python 3 code into the Terminal and run it on a line-by-line basis.ģ. Without additional arguments, the python3 command will invoke the Python 3 interactive interpreter. If you end up using Python 3 as your primary interpreter, you can change this alias, but python3 is the default.Ģ. Notice the difference when compared to the python command, which runs Python 2.7. If you want to run a Python 3 script or application from the command line, you’ll need to use the command python3. It also includes IDLE, an IDE for developing Python applications, a link to Python’s documentation and miscellaneous documents.ġ. This folder contains a GUI for launching Python applications called Python Launcher. The installer also installed the Python interpreter and binaries in your /usr/local/bin folder.Ĥ.

But first, you’ll need to install a Python 3 interpreter on your Mac. If you’re writing new programs in Python, you might be interested in starting to use Python 3. The developers have set 2020 as the final year for Python 2 support, and everyone will need to transition their programs over to Python 3 by then. Unfortunately, Python 2 isn’t going to be around forever. It’s true that utilities like 2to3 make it easier to transform a Python 2 program into valid Python 3 syntax, but if you’ve ever used Google Translate, you know this won’t be perfect. With the significant differences between the two versions and the work required to convert from 2 to 3, it’s hard to find strong reasons to move Python 2 apps to Python 3. Plus, Python 2.7.10 is pre-installed on all Macs and a number of Linux distros.

Python 2 is a strong language, and only power users will get to experience the full benefit of Python 3’s new features. You can check out a list of the most significant changes on the Python 3.0 documentation.īut why hasn’t the whole world switched over to Python 3? The main problem is that there’s a lack of compelling motivation. Even fundamental commands like print and integer comparison work differently between Python 2 and 3, complicating the process of moving from one language to another. That means that programs written for a Python 2 interpreter won’t run on a Python 3 interpreter.
It’s not backwards compatible with Python 2. However, alongside those new features, Python 3 also has a problem.
They wouldn’t be totally wrong: Python 3 includes some cool new features that Python 2 lacks. It’s natural think that Python 3 is better because it’s newer.
