| [1] | The binaries for AMD64 will also work on processors that implement the Intel 64 architecture (formerly EM64T), i.e. the architecture that Microsoft calls x64, and AMD called x86-64 before calling it AMD64. They will not work on Intel Itanium Processors (formerly IA-64). |
| [2] | (1, 2) As of 3.4.0 alpha 2, the Mac OS X 64-bit/32-bit Installer now includes its own private copy of Tcl/Tk so it is no longer necessary to install additional software to use IDLE or tkinter. More detailed information on IDLE, Tkinter, and Tcl/Tk on Mac OS X is available here. |
