How To Download Python 3 On Mac

Historically MacOS came preinstalled with Python 2, however starting with Mac 10.15 (released in October 2019) this is no longer the case. And since Python 2 will no longer be officially supported as of January 1, 2020, you should really use Python 3 instead.

After trying for a long time I managed to make basemap-1.1.0 install on High Sierra. Dependency versioning was important. I installed Python 3.6 with homebrew.

There are various ways to install Python 3, including a download from the official Python site. However, I strongly recommend instead use a package manager like Homebrew to manage all your packages. It will save you from a lot of.

There are multiple ways to install Python 3 on a MacOS computer. The official Python website even recommends downloading it directly, however this approach can cause confusion around PATH variables, updates, and uninstalls. A better approach, in my opinion, is to instead use the popular package manager Homebrew which automates updates and juggling multiple versions of Python on a computer.

Is Python 3 already installed?

Before we start, make sure Python 3 isn’t already installed on your computer. Open up the command line via the Terminal application which is located at Applications -> Utilities -> Terminal.

Then type the command python --version followed by the Enter key to see the currently installed version of Python.

Note: The dollar sign, ($), indicates user input. Everything after is intended to be typed by the user followed by the Enter key. Any output, such as Python 2.7.17 in this case, does not have a dollar sign in front.In short: don’t type $ before your commands!

It’s possible that Python 3 may have already been installed as python3. Run the command python3 --version to check, however most likely this will throw an error.

Install XCode

The first step for Python 3 is to install Apple’s Xcode program which is necessary for iOS development as well as most programming tasks. We will use XCode to install Homebrew.

In your Terminal app, run the following command to install XCode and its command-line tools: How to download biomes o plenty mac.

It is a large program so this make take a while to download. Make sure to click through all the confirmation prompts XCode requires.

Install Homebrew

Next install Homebrew by copy/pasting the following command into Terminal and then type Enter:

To confirm Homebrew installed correctly, run this command:

Install Python 3

Now we can install the latest version of Python 3. Type the following command into Terminal and press Enter:

To confirm which version of Python 3 was installed, run the following command in Terminal:

Finally, to run our new version of Python 3 open an interactive shall by typing python3 within Terminal:

To exit the Python 3 interactive shell, you can type either exit() and then Return or type Control+d which means hold both the Control and D keys at the same time.

Note that it is still possible to run Python 2 by simply typing python:

Virtual Environments

By default, Python packages are installed globally on your computer in a single directory. This can cause major problems when working on multiple Python projects!

Mac Os Python Install

For example, imagine you have Project A that relies upon Django 1.11 whereas Project B uses Django 2.2. If you naively installed Django on your computer, only the latest install would be present and available in that single directory. Then consider that most Python projects rely on multiple packages that each have their own version numbers. There’s simply no way to keep everything straight and not inadvertently break things with the wrong package versions.

The solution is to use a virtual environment for each project, an isolated directory, rather than installing Python packages globally.

Confusingly, there are multiple tools for virtual environments in Python:

• venv is available by default on Python 3.3+
• virtualenv must be installed separately but supports Python 2.7+ and Python 3.3+
• Pipenv is a higher-level tool that automatically manages a separate virtual environment for each project

On MacOS we can install Pipenv with Homebrew.

Then use Pipenv for any Python packages you wish to install. For example, if you want to work with Django 2.2.6, first create a dedicated directory for it on your computer such as in a django directory on your Desktop.

Then install Django within that directory.

If you look within the directory there are now two new files, Pipfile and Pipfile.lock, which Pipenv uses. To activate the virtual environment type pipenv shell.

There will now be parentheses around the name of your current directory which indicates the virtual environment is activate. To exit the virtual environment, type exit.

The lack of parentheses confirms the virtual environment is no longer active.

Python 3 Notes [ HOME LING 1330/2330 ]

Installing Python 3 on a Mac << Previous Note Next Note >>

Steps Head to python.org. Click 'Downloads', then download the latest version from there: This downloads the 64-bit version of the latest Python release (3.8.5 as of August 2020). Alternatively, if you start from the release page such as https://www.python.org/downloads/release/python-385/, you should scroll all the way to the bottom and choose 'macOS 64-bit installer', for OS X 10.9 and later. See screenshot here. NOTE: If your Mac's OS version is older than 10.9 (year 2013), I recommend upgrading your OS first. If you are unable to, see this FAQ for how to install Python on an older version of Mac OS. Proceed with installation. If everything goes fine, you should see an IDLE shortcut in your Launchpad. Go ahead and try it out! Video tutorial here. Should I Re-install? If you already have a working version of Python on your laptop, you might be wondering if it is OK to keep it or you should re-install. The run-down: Already have Python 3 but older version If you previously installed an earlier version of Python 3 (say, 3.3.1 or something), then you should either update it or simply un-install it and then install the newest version of Python 3. That way, you can make sure you are working in the exactly same setup with the rest of the class, which just might save you some headache stemming from a configuration unique to your machine. I have Anaconda Python That works too! Make sure to update it to the latest 3.X version. There is one caveat: in LING 1330/2330, we will be using the interpretive shell interface via IDLE rather than Jupyter Notebook you probably have been using. This is how you launch IDLE for Anaconda Python: Open up a Terminal. Type in idle3 &, followed by ENTER. ('&' keeps Terminal usable while IDLE window is open.)
