I am getting started with Python¶. For new users who want to install a full Python environment for scientific computing and data science, we suggest installing the Anaconda or Canopy Python distributions, which provide Python, IPython and all of its dependences as well as a complete set of open source packages for scientific computing and data science. See full list on opensource.com. May 11, 2017 Installing Python 3 and Pip on Mac OS May 11, 2017 Apple's Mac OS comes with python 2.7 installed by default. Perhaps you may want to use python 3.x.x on your machine and also use pip for package management with python 3.x.x. Jun 13, 2018 Run the Python installer package and install Python 3 onto the Mac Python 3.8.x requires about 100mb of disk space to install. Installation is quick, and you'll have Python 3.x alongside Python 2.x on the Mac. Once Python 3 is installed you will find a Python3 folder within the /Applications directory of your Mac.

The easiest way to achieve this is by:
NOTE: This tutorial does not useVirtual Environments like virtualenv
or pyenv
to manage various python
versions
1. Installing python3
- Follow this link and download the latest
python3
OS X
package - Run the package and follow the steps to install
python3
on your computer. - Once the installation is done, on your
Terminal
, run
This will print out the version of python installed on your system. The output should be similar to:
You may verify the installation directory of python
by runningthe following line on the Terminal
.
The prompt should print the install path for python3
. An example output is:
2. Install pip3
:
Python 3 Download Windows 10
- Securely download the
get-pip.py
file from this link - From the directory where the file was downloaded to, run the following command in the
Terminal
- Once the installation completes you should see the prompt print message similar to this
- Verify the installation of
pip3
by running the following on theTerminal
This should return the install location of pip3
.
- To install
python3
packages usingpip3
, run
Remember to replace packageName
with the appropriate package name for your case.
Happy Pythoning!
Mac OS X comes with Python 2.7 out of the box. Os yosemite review.
You do not need to install or configure anything else to use Python 2. Theseinstructions document the installation of Python 3.
The version of Python that ships with OS X is great for learning, but it's notgood for development. The version shipped with OS X may be out of date from theofficial current Python release,which is considered the stable production version.
Doing it Right¶
Let's install a real version of Python.
Before installing Python, you'll need to install GCC. GCC can be obtainedby downloading Xcode, the smallerCommand Line Tools (must have anApple account) or the even smaller OSX-GCC-Installerpackage.
Note
If you already have Xcode installed, do not install OSX-GCC-Installer.In combination, the software can cause issues that are difficult todiagnose.
Note
If you perform a fresh install of Xcode, you will also need to add thecommandline tools by running xcode-select--install
on the terminal.
While OS X comes with a large number of Unix utilities, those familiar withLinux systems will notice one key component missing: a package manager.Homebrew fills this void.
To install Homebrew, open Terminal
oryour favorite OS X terminal emulator and run
The script will explain what changes it will make and prompt you before theinstallation begins.Once you've installed Homebrew, insert the Homebrew directory at the topof your PATH
environment variable. You can do this by adding the followingline at the bottom of your ~/.profile
file
If you have OS X 10.12 (Sierra) or older use this line instead
Now, we can install Python 3:
This will take a minute or two.
Pip¶
Homebrew installs pip
pointing to the Homebrew'd Python 3 for you.
Working with Python 3¶
Pycharm
At this point, you have the system Python 2.7 available, potentially theHomebrew version of Python 2 installed, and the Homebrewversion of Python 3 as well.
will launch the Homebrew-installed Python 3 interpreter.
will launch the Homebrew-installed Python 2 interpreter (if any).
will launch the Homebrew-installed Python 3 interpreter.
If the Homebrew version of Python 2 is installed then pip2
will point to Python 2.If the Homebrew version of Python 3 is installed then pip
will point to Python 3.
The rest of the guide will assume that python
references Python 3.
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!
