[1](1, 2) 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) There is important information about IDLE, Tkinter, and Tcl/Tk on Mac OS X here. Also, on Mac OS X 10.6, if you need to build C extension modules with the 32-bit-only Python installed, you will need Apple Xcode 3, not 4. The 64-bit/32-bit Python can use either Xcode 3 or Xcode 4.
