Installing Python 3 on Windows
|
|
==============================
|
|
|
|

|
|
|
|
First, follow the installation instructions for `Chocolatey <https://chocolatey.org/install>`_.
|
|
It's a community system packager manager for Windows 7+. (It's very much like Homebrew on OSX.)
|
|
|
|
Once done, installing Python 3 is very simple, because Chocolatey pushes Python 3 as the default.
|
|
|
|
.. code-block:: console
|
|
|
|
choco install python
|
|
|
|
Once you've run this command, you should be able to launch Python directly from to the console.
|
|
(Chocolatey is fantastic and automatically adds Python to your path.)
|
|
|
|
Setuptools + Pip
|
|
----------------
|
|
|
|
The two most crucial third-party Python packages are `setuptools <https://pypi.python.org/pypi/setuptools>`_ and `pip <https://pip.pypa.io/en/stable/>`_,
|
|
which let you download, install and uninstall any compliant Python software
|
|
product with a single command. It also enables you to add this network installation
|
|
capability to your own Python software with very little work.
|
|
|
|
All supported versions of Python 3 include pip, so just make sure it's up to date::
|
|
|
|
python -m pip install -U pip
|
|
|
|
|
|
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 projects
|
|
in 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 keeps
|
|
your global site-packages directory clean and manageable.
|
|
|
|
For example, you can work on a project which requires Django 2.0 while also
|
|
maintaining a project which requires Django 1.8.
|
|
|
|
So, onward! To the :ref:`Pipenv & Virtual Environments <virtualenvironments-ref>` docs!
