Windows users

  • 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".)
  • If installing Python 3.6 as a non-privileged user, you may need to escalate to administrator privileges to install an update to your C runtime libraries.
  • 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.

macOS users

  • NEW as of 3.6.5: we are providing two binary installer options for download. The new variant works on macOS 10.9 (Mavericks) and later systems and comes with its own batteries-included version oF Tcl/Tk 8.6 for users of IDLE and other tkinter-based GUI applications. It is 64-bit only as Apple is deprecating 32-bit support in future macOS releases. For 3.6.5, the 10.9+ variant is offered as an additional more modern alternative to the traditional 10.6+ variant in earlier 3.6.x releases. The 10.6+ variant still requires installing a third-party version of Tcl/Tk 8.5. If you are using macOS 10.9 or later, consider using the new installer variant, unless you are building Python applications that also need to work on older macOS systems. Binary extension modules (including wheels) built for earlier versions of 3.6.x with the 10.6 variant should continue to work with either 3.6.5 variant without recompilation.
  • If you are using Python 3.6.5 from one of the python.org binary installers linked to on this page, please carefully read the Important Information displayed during installation; this information is also available after installation by clicking on /Applications/Python 3.6/ReadMe.rtf. There is important information there about changes in the 3.6 installer-supplied Python, particularly with regard to SSL certificate validation.
