Release Date: Aug. 17, 2020

Python 3.7.9 is the latest security fix release of Python 3.7.

Python for Mac OS X. Python comes pre-installed on Mac OS X so it is easy to start using. However, to take advantage of the latest versions of Python, you will need to download and install newer versions alongside the system ones. The easiest way to do that is to install one of the binary installers for OS X from the Python Download page. In the Terminal app on your Mac, in the window running the shell process you want to quit, type exit, then press Return. This ensures that commands actively running in the shell are closed. If anything’s still in progress, a dialog appears. If you want to change the shell exit behavior, see Change Profiles Shell preferences.

Quit stops the TCL interpreter. This is in most cases what you want, because your Tkinter-app will also stop. It can be a problem, if you e.g. Call your app from idle. Idle is itself a Tkinker-app, so if you call quit in your app and the TCL interpreter gets terminated, idle will also terminate (or get confused;)). Business Applications. Python is also used to build ERP and e-commerce systems: Odoo is an all-in-one management software that offers a range of business applications that form a complete suite of enterprise management applications. Tryton is a three-tier high-level general purpose application platform.

Python 3.8 is now the latest feature release series of Python 3. Get the latest release of 3.8.x here. Python 3.7.8 was the last bugfix release for 3.7. Python 3.7 is now in the security fix phase of its life cycle. Only security-related issues are accepted and addressed during this phase. We plan to provide security fixes for Python 3.7 as needed until mid 2023, five years following its initial release. Security fix releases are produced periodically as needed and are source-only releases.

Binary installers are normally not provided for security fix releases. However, since 3.7.8 was the last 3.7.x bugfix release and there are security fixes published in 3.7.9 that apply to users of some of the binary installers provided with 3.7.8, we have made an exception for 3.7.9 and are also updating the Windows and macOS binary installers. We do not plan to provide further binary updates for future 3.7.x security releases.

  • The binaries for AMD64 will also work on processors that implement the Intel 64 architecture. (Also known as the 'x64' architecture, and formerly known as both 'EM64T' and 'x86-64'.)
  • There are now 'web-based' installers for Windows platforms; the installer will download the needed software components at installation time.
  • There are redistributable zip files containing the Windows builds, making it easy to redistribute Python as part of another software package. Please see the documentation regarding Embedded Distribution for more information.
  • Please read the 'Important Information' displayed during installation for information about SSL/TLS certificate validation and the running the 'Install Certificates.command'.
  • As of 3.7.7, we provide one installer: 64-bit-only that works on macOS 10.9 (Mavericks) and later systems. The deprecated 64-bit/32-bit installer variant for macOS 10.6 (Snow Leopard) is no longer provided.
  • As of 3.7.7, macOS installer packages are now compatible with the full Gatekeeper notarization requirements of macOS 10.15 Catalina including code signing.
