These instructions document the installation of Python 3. The version of Python that ships with OS X is great for learning, but it's not good for development. The version shipped with OS X may be out of date from the official current Python release, which is considered the stable production version. This brief guide is written because many people search hot to Update Python on MAC computers. So we will show you how to install Python 3 on a Mac OS X computer. Before you jump in the manual, do take note that there are a number of ways to install Python 3 on a Mac but with this guide, I'll show you the two easiest ways to do so. One can install Python without using the terminal on MacBook Air or Mac. For this, you need to download the Python installer from the python.org website. Follow the steps below: Visit Python.org and download the latest available Python 3 installer file. Run the downloaded file and install Python 3.x on your macOS. After completing the.
Tldr; install brew; brew install python. Homebrew is a great installer for Mac and its main job is to make it easier to install packages. Step 1: Download Homebrew here 'brew' hosts its package information here as 'formulae'. Step 2: Use brew to install the latest version of Python $ brew install python -verbose.
This article will help you to set up a Python virtual environment on Mac OS or your Macbook. If you are a Mac user, you should know that Python 2.7.x comes pre-installed in your Macbook, but as that is required by your operating system, so you cannot modify it or update it and I would recommend that you don't use it at all.
Instead, you should set up a virtual environment for your development purpose. You must be thinking about why we need a virtual environment? So here are a few points in its favor:
When we have a virtual environment, then we can install new packages inside the virtual environment which will not affect the operating system's python modules.
We can have different versions of Python installed inside the virtual environment.
You can set up a different virtual environment for each project for example if you are working on one project based on Tkinter module, some other projects based on Numpy module, then you can easily do this.
So to set up a virtual environment, we won't be using virtualenv or virtualenvwrapper module, which are most popular to set up a virtual environment.
But we will be using the venv module which comes as a default with Python 3.x version and is recommended to use for virtual environment creation.
Installing Python 3.8 on Mac OSX
We will use Homebrew to install Python 3.8 and will then move on to creating a virtual environment. If you don't have Homebrew installed on your Macbook, you can install Homebrew on your MacOSX and then use it to install Python 3.8 on your machine.
Once you have Homebrew set up, run the following command to install the latest version of Python:
Homebrew will also install pip for you which you can verify by running the pip3 command.
To verify the successful installation of Python 3.x version, run the python3 command and the IDLE should start in your terminal.
Use venv to create Virtual Environment
As per the official documentation of venv module,
The venv module provides support for creating lightweight 'virtual environments' with their own site directories, optionally isolated from system site directories. Each virtual environment has its own Python binary (which matches the version of the binary that was used to create this environment) and can have its own independent set of installed Python packages in its site directories.
We can run the following command to create a virtual environment: Hard disk analyzer mac.
This will create a virtual environment for you with the following files in the virtual environment directory my_env:
- bin
- include
- lib
- pip-selfcheck.json
- pyvenv.cfg
To activate the virtual environment, run the following command: Download office 2018 for mac.
This will start the virtual environment and you should see the name of the virtual environment added before the directory name as shown in the image below:
Now you can install anything in it, by running the pip3 install command, for example to install the requests module, run the following command:
To get out of the virtual environment, run the exit command.
Conclusion:
With this you have the complete virtual environment setup, now create any .py script and try running it in the virtual environment. Also, you can install as many modules as you want in the virtual environment.

Step 1: Download Homebrew here
'brew' hosts its package information here as 'formulae'.
Step 2: Use brew to install the latest version of Python
$ brew install python --verbose How to mount a external hard drive on mac.
Now you can run python3 in your terminal
> python3
More details: So what happens when I run brew install?
When you run the command, brew will look for the package in the 'formulae' list and run the installation script for the package.
Brew installs *all* packages into its own directory on your computer at /usr/local/Cellar .
Take a look with $ ls /usr/local/Cellar.
Mac Upgrade Python 3
After installation, brew creates a symlink which is basically a shortcut that will allow your system to run the new command > python3.
