First, download the `latest version <https://www.python.org/ftp/python/3.6.4/python-3.6.4.exe>`_
of Python 3.6 from the official website. If you want to be sure you are installing a fully
up-to-date version, click the Downloads > Windows link from the home page of the
`Python.org web site <http://python.org>`_.
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.)
By design, Python installs to a directory with the version number embedded,
e.g. Python version 3.6 will install at :file:`C:\\Python36\\`, so that you can
have multiple versions of Python on the
same system without conflicts. Of course, only one interpreter can be the
default application for Python file types. It also does not automatically
modify the :envvar:`PATH` environment variable, so that you always have control over
which copy of Python is run.
Typing the full path name for a Python interpreter each time quickly gets
tedious, so add the directories for your default Python version to the :envvar:`PATH`.
Assuming that your Python installation is in :file:`C:\\Python36\\`, add this to your
:envvar:`PATH`:
Once done, installing Python 3 is very simple, because Chocolatey pushes Python 3 as the default.
.. code-block:: console
C:\Python36\;C:\Python36\Scripts\
You can do this easily by running the following in ``powershell``:
.. code-block:: console
[Environment]::SetEnvironmentVariable("Path", "$env:Path;C:\Python36\;C:\Python36\Scripts\", "User")
This is also an option during the installation process.
The second (:file:`Scripts`) directory receives command files when certain
packages are installed, so it is a very useful addition.
You do not need to install or configure anything else to use Python. Having
said that, I would strongly recommend that you install the tools and libraries
described in the next section before you start building Python applications for
real-world use. In particular, you should always install Setuptools, as it
makes it much easier for you to use other third-party Python libraries.
Working with Python 3
---------------------
At this point, you may also have Python 2.7 installed.
.. code-block:: console
$ python
This will launch the Python 2 interpreter.
.. code-block:: console
$ python3
This will launch the Python 3 interpreter.
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.)
