- Jul 12, 2014 Install Python 3 on Mac OS X and use virtualenv and virtualenvwrapper July 12, 2014 February 21, 2015 Marina Mele This post explains how to install Python 3 in a Mac OS X.
- To install pip, follow the official pip installation guide - this will automatically install the latest version of setuptools. Note that on some Linux distributions including Ubuntu and Fedora the pip command is meant for Python 2, while the pip3 command is meant for Python 3.
This method has only been tested on OS X 10.7 and above (64-bit). For versions prior to 10.7 or 10.7 32-bit, you have to install the components yourself. For OS X 10.13.5 and later, we provide packages with all dependencies bundled in a virtual environment, including a Python interpreter for python3 version. Install Python 3 on MacOS. 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. There are multiple ways to install Python 3 on a MacOS computer.
This document describes how to install Python 3.6 on Ubuntu Linux machines.
To see which version of Python 3 you have installed, open a command prompt and run
If you are using Ubuntu 16.10 or newer, then you can easily install Python 3.6 with the following commands:
If you’re using another version of Ubuntu (e.g. the latest LTS release), we recommend using the deadsnakes PPA to install Python 3.6:
If you are using other Linux distribution, chances are you already have Python 3pre-installed as well. If not, use your distribution’s package manager.For example on Fedora, you would use dnf:
Note that if the version of the
python3
package is not recent enoughfor you, there may be ways of installing more recent versions as well,depending on you distribution. For example installing the python36
packageon Fedora 25 to get Python 3.6. If you are a Fedora user, you might wantto read about multiple Python versions available in Fedora.Working with Python 3¶
At this point, you may have system Python 2.7 available as well.
This will launch the Python 2 interpreter.
This will launch the Python 3 interpreter.
Setuptools & Pip¶
The two most crucial third-party Python packages are setuptools and pip.
Once installed, you can download, install and uninstall any compliant Python softwareproduct with a single command. It also enables you to add this network installationcapability to your own Python software with very little work.
Python 2.7.9 and later (on the python2 series), and Python 3.4 and later includepip by default.
To see if pip is installed, open a command prompt and run
To install pip, follow the official pip installation guide - this will automatically install the latest version of setuptools.
Os X Python 3
Note that on some Linux distributions including Ubuntu and Fedora the
pip
command is meant for Python 2, while the pip3
command is meant for Python 3.However, when using virtual environments (described below), you don’t need tocare about that.
Pipenv & Virtual Environments¶
The next step is to install Pipenv, so you can install dependencies and manage virtual environments.
A Virtual Environment is a tool to keep the dependencies required by different projectsin separate places, by creating virtual Python environments for them. It solves the“Project X depends on version 1.x but, Project Y needs 4.x” dilemma, and keepsyour global site-packages directory clean and manageable.

For example, you can work on a project which requires Django 1.10 while alsomaintaining a project which requires Django 1.8.
So, onward! To the Pipenv & Virtual Environments docs!

This post explains how to install Python 3 in a Mac OS X, both Mavericks and Yosemite. Check this post if you want to clean install Python 2.7. You can also install both! 🙂
It also shows how to use virtualenv and virtualenvwrapper with Python 3. Don’t miss it!
Like with Python 2.7, we need to install first Xcode and Homebrew.
Install Xcode and Homebrew
First of all, install Xcode if you don’t have it already. You can find it in the Apple Store.
Some applications are setup to take advantage of large screens automatically. Excel is a good example. If you fill your screen with Excel it will show you more cells and you can view more of a spread sheet at a time. Other applications take a bit of configuration to make things work efficiently. Feb 12, 2017 Excel row numbers and column letters are too big I am using excel version 15.31 on a Mac. The mac is running OS 10.12.3. The row numbers down the. Excel os x spreadsheet too large for screen. May 25, 2017 7 Excel tips for huge spreadsheets: Split Screen, Freeze Panes, Format Painter and more The bigger and uglier your spreadsheet is, the more you need to keep a handle on the data. Note: Watch this short tutorial screencast or follow the quick steps below, that compliment this video. Open the Excel Screenshot Windows. Start off by making sure that you're on the Insert tab in Excel. Then, find the Screenshot button here on the ribbon. When you click on it, you'll see thumbnails for the other open apps on your computer. Feb 11, 2015 I have an Excel spreadsheet that I can't resize because it extends beyond the bottom of the screen. Same spreadsheet works on my secretary's iMac and we are running the same OS 10.10. The resize button is no help because that causes the computer to go into full screen mode and then the resize box at the bottom right corner is not there.
Next, we need to install the Command Line Tools of Xcode. Open a Terminal and type:
this should trigger a pop-up window that will ask you to install the Command Line Tools. If you have some trouble installing these tools, you might find useful this post on Stackoverflow.
Next, we need to install Homebrew. In the Terminal, type this command line:
$ruby-e'$(curl -fsSL https://raw.githubusercontent.com/Homebrew/install/master/install)' |
Now, we need to insert the Homebrew directory at the top of the PATH environment variable. In this way, some Homebrew installations will take precedence over stock OS X binaries. Open or create the file ~/.bash_profile and write:
Close your Terminal and open it again to make these changes effective.
Install Python 3
If you type
you will see the available python-related packages to install, and python3 should be among them. Let’s install it!
You can check which version is installed by typing
And you can open it with:
Moreover, when you install python with Homebrew, you also install:
- the corresponding pip package manager, which is called pip3
- the corresponding Setuptools
- pyvenv, and alternative to virtualenv — cool!!
Create Virtual environments with pyvenv
Now that you have Python3 you also have pyvenv, a tool to create virtual environments (similar to virtualenv). However, there is one important remark about the version of pyvenv you have installed: only if you installed Python 3.4 or latter, pyvenv will also install pip when creating a new virtual environment.
Let’s create a new virtual envirnoment, named myenv, using pyvenv:
This will create a folder named myenv in the current directory. To activate this environment just type:
and you can start Python 3 by just typing:
Note that as you are inside the virtual environment, you don’t need to use the command python3 to open Python 3.Virtualenvwrapper with Python 3
Many of you will be familiar with virtualenvwrapper, a nice tool to manage more easily your virtual environments.To install it, we will first install virtualenv:
