This is a prerelease version of Python 3.x.

Python 3.x

3.7.0-a2

This package skips automatic verification:

Needs to install some Windows updates if they are missing, however it doesn't know how to do that. The exit code is 23, which is a CRC error, so it is technically probably not even correct - https://msdn.microsoft.com/en-us/library/windows/desktop/ms681382(v=vs.85).aspx


This package was approved as a trusted package on 11/10/2017.

Python 3.x is a programming language that lets you work more quickly and integrate your systems more effectively. You can learn to use Python 3.x and see almost immediate gains in productivity and lower maintenance costs.

Package Parameters

  • /InstallDir - Installation directory

These parameters can be passed to the installer with the user of --params.
For example: --params '"/InstallDir:C:\tools\python2"'

Notes

  • This package installs the latest stable version of Python 3.x. It will install to Python 3.x to C:\Python3x.
  • This package is not intended to use with Chocolatey's -x86 parameter. If you want a 32-bit Python 3.x on 64-bit systems, install the {{PackageName}}-x86_32 package instead. You can also install both. In that case you must manually adapt your .exe shims so that it picks the desired version when you invoke python.exe.

To install Python 3.x, run the following command from the command line or from PowerShell:

C:\> choco install python3 --pre

To upgrade Python 3.x, run the following command from the command line or from PowerShell:

C:\> choco upgrade python3 --pre

    A. HISTORY OF THE SOFTWARE
    ==========================
    
    Python was created in the early 1990s by Guido van Rossum at Stichting
    Mathematisch Centrum (CWI, see http://www.cwi.nl) in the Netherlands
    as a successor of a language called ABC.  Guido remains Python's
    principal author, although it includes many contributions from others.
    
    In 1995, Guido continued his work on Python at the Corporation for
    National Research Initiatives (CNRI, see http://www.cnri.reston.va.us)
    in Reston, Virginia where he released several versions of the
    software.
    
    In May 2000, Guido and the Python core development team moved to
    BeOpen.com to form the BeOpen PythonLabs team.  In October of the same
    year, the PythonLabs team moved to Digital Creations (now Zope
    Corporation, see http://www.zope.com).  In 2001, the Python Software
    Foundation (PSF, see http://www.python.org/psf/) was formed, a
    non-profit organization created specifically to own Python-related
    Intellectual Property.  Zope Corporation is a sponsoring member of
    the PSF.
    
    All Python releases are Open Source (see http://www.opensource.org for
    the Open Source Definition).  Historically, most, but not all, Python
    releases have also been GPL-compatible; the table below summarizes
    the various releases.

    Footnotes:
    
    (1) GPL-compatible doesn't mean that we're distributing Python under
        the GPL.  All Python licenses, unlike the GPL, let you distribute
        a modified version without making your changes open source.  The
        GPL-compatible licenses make it possible to combine Python with
        other software that is released under the GPL; the others don't.
    
    (2) According to Richard Stallman, 1.6.1 is not GPL-compatible,
        because its license has a choice of law clause.  According to
        CNRI, however, Stallman's lawyer has told CNRI's lawyer that 1.6.1
        is "not incompatible" with the GPL.
    
    Thanks to the many outside volunteers who have worked under Guido's
    direction to make these releases possible.

Virus Scan Results

In cases where actual malware is found, the packages are subject to removal. Software sometimes has false positives. Moderators do not necessarily validate the safety of the underlying software, only that a package retrieves software from the official distribution point and/or validate embedded software against official distribution point (where distribution rights allow redistribution).

Chocolatey Pro provides runtime protection from possible malware.
