Python is a popular programming language that is widely used by both beginners and professional developers. Modern versions of Mac OS support Python 2.7.x (or Python 2.6.1 in older versions), but many users need to upgrade to Python 3.6 or 3.7. Today I will explain how to install the Python 3 update on a Mac in two different ways. How to Download and Install Python 3.6.1 on macOS Mac OS X Sierra,Mojave mac OS macOS version is the thirteenth major release of macOS previously OS X, Apple Inc.' S desktop and server operating. Default meaning of Python on the command-line may not be clear. Python is usually an alias for python2.7 (but it can sometimes be an alias for older versions like python2.6 or python2.5). To find out exactly which version of Python you're using, you can use the -version flag. $ python -version Python 3 is usually available under the name of.

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:

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:

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.

Mac training book. 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:

Wifispoof 3 1 – change your wifi mac address account. 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.

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:

after which you will need to use the plt.show() function in order to actually see the result of the plt.plot https://hallfree.mystrikingly.com/blog/mac-create-file-terminal. function.

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:

Note:With the release of macOS Sierra sometime in Fall 2016, we will be updating theseinstallation instructions (if needed) to support the newest Apple operating system.These instructions have been tested on macOS Sierra beta 7. Students are encouragedto upgrade to macOS Sierra when the software is officially released by Apple; theupgrade process should not corrupt your Python 3.5 and WingIDE installation.

Install Miniconda Python 3.5.2¶

To get started point your browser at

Then,

1. Click on OS X Miniconda install
2. Click on the Miniconda installer for OS X
   1. On this page select the 64-bit (bash installer) for Python3.5 and Mac OS X
   2. Wait for it to download. It will place a file calledMiniconda3-latest-MacOSX-x86_64.sh in your downloadsfolder. On my computer using Safari this is ~/Downloads
   3. Using your browser go back to the previous page
3. Open at Terminal window. If you don’t know how to do this click *Applications -> Utilities -> Terminal*
4. Within Terminal “change directories into the folder where your cd ~/Downloads
5. Now run the bash “shell” program to install Miniconda

6. Scroll through the license (press the space bar to move throughquickly), type ‘yes’ to approve the terms, and then accept all theinstallation defaults.
7. Close the Terminal program. Then, restart it.
8. Within Terminal type:

conda install pillow

2. Enter y at the Proceed prompt.
3. When the installation completes, close the Terminal window.

Install Wing IDE and Connect It to Miniconda Python¶

The second half of the installation is the Wing IDE developmentenvironment. This is the software that you use to write, edit andtest your Python programs. Wing IDE calls Python to actually run theprogram. Therefore, we have to download and install Wing IDE and thentie it to the Miniconda version of Python.

Using Python On Mac

1. Go to http://wingware.com/downloads/wingide-101
2. Download the installer for your operating system. For Mac OS Xthis downloads an installation dmg package. Double click on it toinstall and follow the instructions. As with miniconda, you may needto answer of few questions and accept the license agreement. You shoulduse the default settings.
3. Open the Wing IDE application. We’ll explore this application inlecture and in lab, but for now we just need to tell Wing aboutMiniconda Python. To do this, click on the menu and then Edit ->Configure Python
4. For the Python Executable click on Custom and then Browse to thelocation for the Miniconda Python executable. On my Mac this is/Users/stewart/miniconda3/bin/python3.5 See the following

5. Ignore the Python Path and all other settings and click OK.
6. Back in the main Wing IDE it may ask you to restart the pythonshell. Once you do then you should see at the top of the PythonShell window pane something about “3.5.2 |Continuum Analytics,Inc.” etc. If you have this you are all set and the installationis complete!

Detecting 64-bits versus 32-bits Mac OS X Systems¶

You are running 64-bit Mac OS X.

Technically, all Apple computers purchased since Q4 2006 have been equipped with64-bit capable processors. The Mac OS X operating system has supported 64-bit bydefault since OS X 10.6 Snow Leopard, released in 2009. The upgrade to the latestoperating system for your computer is available for free, directly from Apple,since the release of OS X 10.9 Mavericks in 2013.
