This is not the latest version of Python available.

Python

3.4.3

There are no package test results for this package

This package was approved by moderator gep13 on 3/19/2015.

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

Note

This package installs the latest stable version of Python. It will install to Python to $env:ChocolateyBinRoot\python, but only if Python is not already installed where the installer puts it by default, which is $env:SystemDrive\PythonXX (XX stands for the major/minor version digits).

This package is not intended to use with Chocolatey’s -x86 parameter. If you want a 32-bit Python on 64-bit systems, install the python-x86_32 package instead. You can also install both packages. In this case you must manually adapt your PATH environment variable so that it picks the Python version that you want when invoking python.exe.

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

C:\> choco install python --version 3.4.3

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

C:\> choco upgrade python --version 3.4.3

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.
