Python for Mac OS X
Python comes pre-installed on Mac OS X so it is easy to startusing. However, to take advantage of the latest versions ofPython, you will need to download and install newer versionsalongside the system ones. The easiest way to do that is toinstall one of the binary installers for OS X from thePython Download page. Installers areavailable for the latest Python 3 and Python 2 releases thatwill work on all Macs that run Mac OS X 10.5 and later.

Which python ? version(s) on Mac OS Mojave. Posted by 2 years ago. Which python ? version(s) on Mac OS Mojave. I don’t have the time to download and test this myself, but since python 2 will eol soon, I’d love to know what apple is planning. Save hide report. Mac OS X 10.8 comes with Python 2.7 pre-installed by Apple. If you wish, you are invited to install the most recent version of Python 3 from the Python website (A current “universal binary” build of Python, which runs natively on the Mac’s new Intel and legacy PPC CPU’s, is available there.
Python releases include IDLE, Python's built-in interactivedevelopment environment. If you download and install Pythonfrom the release page, you may also need to download and installa newer version of Tcl/Tk for OS X. See theIDLE and Tkinter on OS X page formore information.
You can run a Python interpreter by double-clicking onApplications / Utilities / Terminal and typing python3 (if you'veinstalled a version of Python 3) or python (to use Python 2) inthe window that opens up. You can also launch IDLE for the Pythonversion you have installed by double-clicking its icon inthe appropriate Python version folder in the Applications folderor you can also just type idle3 or idle in a terminal window.
There are many thousands of additional Python software packagesavailable through PyPI, the PythonPackage Index. We recommend you use thepip tool to simplifyinstalling and managing additional packages. pip is includedwith Python 3.4 releases; for earlier releases, follow the pipinstall instructions.
Among the packages available through PyPI are some that arespecifically for OS X environments. Among these are:
- pyobjc which providesa bridge between Python and Objective-C, allowing you to writefull-featured native Cocoa applications in pure Python.
- py2app which allowsyou to make standalone OS X double-clickable application bundlesand plugins from Python scripts.
For more information about Python on OS X, see the mailing list and archivesfor thePython-Macintosh Special Interest Group.
Alternative Packages for Mac OS X.
- ActiveState ActivePython(commercial and community versions, including scientific computing modules).
- Enthought Python DistributionThe Enthought Python Distribution provides scientists with a comprehensive setof tools to perform rigorous data analysis and visualization.
Python and a comprehensive set of third-party packages and libraries are alsoavailable from several open source package manager projects for OS X,including:

In this article, I will show you how to install Python 3 with NumPy, SciPy and Matplotlib on macOS Catalina.
There is also a video version of this tutorial:
MacOS comes by default with Python 2.7 which, at this point, receives only bug fixes and will be EOL by 2020. Python 3.x is the future and it is supported by all major Python libraries. In this tutorial, we’ll use Python 3.8.
Start by installing the Command Line Tools for macOS. Please note, that you will need the Command Line Tools even if you’ve already installed Xcode. Open a Terminal and write:
Backgrounds 3 0 – dynamic desktop wallpapers free. Once the Command Line Tools are installed, we can install Python.
The official installer of Python is a pkg file that will start a GUI installer which will guide you through the installation. You can also check the video version of this tutorial if you want to see how I did it.
As a side note, you can have multiple Python 3 versions installed on your macOS machine. If this is the case, you can select which version you want to use by specifying the version number, e.g.:
or:
After the above, you can invoke Python 3.8 using the python3.8 command. python3 will also invoke the latest installer version of Python 3. This is what I see if I run python3.8 on my machine:
Next, let’s follow best practices and create a new Python environment in which we can install NumPy, SciPy and Matplotlib:
![For For](https://pyimagesearch.com/wp-content/uploads/2019/01/macos_mojave_dl_install_keras_config.jpg)
At this point, your prompt should indicate that you are using the work environment. You can read more about Python environment in the documentation.
Once an environment is activated, all the install commands will apply only to the current environment. By default, if you close your Terminal, the environment is deactivated. If you want to be able to use it, use the source work/bin/activate command.
We can install NumPy, SciPy and Matplotlib with:
As a side note, when you are in an active environment you can use the python command to invoke the Python interpreter, no need to use the version number.
Fire up Python, import scipy and print the version of the installed library. This is what I see on my machine:

Let’s try something a bit more interesting now, let’s plot a simple function with Matplotlib. First, we’ll import SciPy and Matplotlib with:
Next, we can define some points on the (0, 1) interval with:
Now, let’s plot a parabola defined on the above interval:
Dictionary english russian. You should see something like this:
As you’ve probably noticed, plt.show() is a blocking command. You won’t be able to use the interpreter until you close Figure 1.
Python Install Mac Os
There is also an interactive mode in which you can plot functions. Close Figure 1 and write:
This is what you should see:
At any point you can disable the interactive plot mode with:
Python For Mac
after which you will need to use the plt.show() function in order to actually see the result of the plt.plot function.
Wd easystore mac. If you want to learn more about Python and Matplotlib, I recommend reading Python Crash Course by Eric Matthes. The book is intended for beginners, but has a nice Data Visualization intro to Matplotlib chapter:
Another good Python book, for more advanced users, which also uses Matplotlib for some of the book projects is Python Playground by Mahesh Venkitachalam:
