Sponsors

Visionary sponsors like Google help to host Python downloads.

Licenses

All Python releases are Open Source. Historically, most, but not all, Python releases have also been GPL-compatible. The Licenses page details GPL-compatibility and Terms and Conditions.

Sources

For most Unix systems, you must download and compile the source code. The same source code archive can also be used to build the Windows and Mac versions, and is the starting point for ports to all other platforms.

Download the latest Python 3 and Python 2 source.

Alternative Implementations

This site hosts the «traditional» implementation of Python (nicknamed CPython). A number of alternative implementations are available as well.

History

Python was created in the early 1990s by Guido van Rossum at Stichting Mathematisch Centrum in the Netherlands as a successor of a language called ABC. Guido remains Python’s principal author, although it includes many contributions from others.

Release Schedules

Information about specific ports, and developer info

OpenPGP Public Keys

Source and binary executables are signed by the release manager or binary builder using their OpenPGP key. Release files for currently supported releases are signed by the following:

Release files for older releases which have now reached end-of-life may have been signed by one of the following:

  • Anthony Baxter (key id: 0EDD C5F2 6A45 C816)
  • Georg Brandl (key id: 0A5B 1018 3658 0288)
  • Martin v. Löwis (key id: 6AF0 53F0 7D9D C8D2)
  • Ronald Oussoren (key id: C9BE 28DE E6DF 025C)
  • Barry Warsaw (key ids: 126E B563 A74B 06BF, D986 6941 EA5B BD71, and ED9D77D5)

You can import a person’s public keys from a public keyserver network server you trust by running a command like:

or, in many cases, public keys can also be found at keybase.io. On the version-specific download pages, you should see a link to both the downloadable file and a detached signature file. To verify the authenticity of the download, grab both files and then run this command:

Note that you must use the name of the signature file, and you should use the one that’s appropriate to the download you’re verifying.

  • (These instructions are geared to GnuPG and Unix command-line users.)

Other Useful Items

  • Looking for 3rd party Python modules? The Package Index has many of them.
  • You can view the standard documentation online, or you can download it in HTML, PostScript, PDF and other formats. See the main Documentation page.
  • Information on tools for unpacking archive files provided on python.org is available.
  • Tip: even if you download a ready-made binary for your platform, it makes sense to also download the source. This lets you browse the standard library (the subdirectory Lib) and the standard collections of demos (Demo) and tools (Tools) that come with it. There’s a lot you can learn from the source!
  • There is also a collection of Emacs packages that the Emacsing Pythoneer might find useful. This includes major modes for editing Python, C, C++, Java, etc., Python debugger interfaces and more. Most packages are compatible with Emacs and XEmacs.

Python

Python is a scripting language that is popular for system automation and machine learning (ML). You can learn more about Python at python.org.

Using Python on x64 or x86

To install Python on Windows IoT Core:

Download the Python NuGet package, and then install the files using PowerShell.

Add Python to the system path.

Ensure that the current version of pip is installed

Using Python on Windows IoT Core ARM32

To get Python for Windows, you will need to build the binaries yourself.

Build Python for ARM32. The branch must be 3.8 or greater.

Build Python .zip file for Windows IoT Core ARM32. The same version of Python must be used to run PC/layout. This step builds Python for x86 and uses it to build the .zip file(s). If you want the standard library tests in your .zip file add the —include-tests parameter.

Use PowerShell to extract the .zip file on the device and add Python to the system path.

Verify that print(‘Hello World’) works.

Using Python on Windows IoT Core ARM64

To get Python for Windows, you will need to build the binaries yourself.

Clone Python for ARM32 and run get_externals . The branch must be 3.8 or greater.

Clone and build libffi.

Build Python for ARM64.

Build Python .zip file for Windows IoT Core ARM64. The same version of Python must be used to run PC/layout. This step builds Python for x86 and uses it to build the .zip file(s). If you want the standard library tests in your .zip file add the —include-tests parameter.

Add Python to the system path.

Verify that print(‘Hello World’) works.

Try out Azure IoT Hub Python SDKs v2 — PREVIEW

First install the SDK.

In the output for the pip install there may be errors: Download error on https://pypi.org/simple/pbr/ . If you see this then, otherwise skip to Set up an IoT Hub and create a Device Identity :

Navigate to https://pypi.org/simple/pbr/ in your favorite browser. Inspect the web site’s certificate and noticed that it issued by DigiCert .

Create a directory named c:\test .

Run certmgr.msc from a command prompt on a desktop Windows machine.

Navigate to Trusted Root Certification Authorities in the treeview. Expand the node and choose Certificates .

In the right pane find the DigiCert High Assurance EV Root , right-click and select All Tasks > Export . Note that there are multiple DigiCert certs and I identified this one by trying each one, one at a time.

In the dialog that pops up click Next .

Select DER encoded binary X.509 (.CER) (this should be the default) and click Next .

In the File name: edit box type c:\test\DigiCert High Assurance EV Root.cer

Copy c:\test\DigiCert High Assurance EV Root.cer to the device by running the following command on your desktop machine:

On the device, import the certificate into the root store using PowerShell.

Try to install the azure-iot-device again

In the output for the pip install there may be errors: Download error for https://files.pythonhosted.org/ . If you don’t see this, then skip to Set up an IoT Hub and create a Device Identity

Navigate to https://files.pythonhosted.org/ in your favorite browser. Inspect the web site’s certificate and noticed that it issued by GlobalSign .

Repeat the steps to export the GlobalSign Root CA certificate from your desktop machine and import it on the device.

Try to install the azure-iot-device again.

Set up an IoT Hub and create a Device Identity

  • Note that this operation may take a few minutes.

Add the IoT Extension to the Azure CLI, and then register a device identity

It should be in the format:

Send a simple telemetry message

Begin monitoring for telemetry on your IoT Hub using the Azure CLI

On your device, set the Device Connection String as an environment variable called IOTHUB_DEVICE_CONNECTION_STRING .

Copy simple_send_d2c_message.py and run it on the device.

Using Python in an x64 docker container on Windows IoT Core

Download the newest docker, and install files.

Copy Dockerfile to c:\docker on device. Also copy any certificates to P:\docker\test. 1.txt is a file with the number 1 and a carriage return.

Connect to the device using SSH. Remote PowerShell will not work for an interactive docker session.

Print hello world

See Azure IoT SDK directions above to test cloud to device messages.
