I presume you mean the Mac Bootcamp program that allows one to run Windows on Macs.  I don't know if it runs *all* Windows programs or whether we specifically support running Windows python under Bootcamp.  I imagine that there might be problems with some GUI and graphics programs.

IDLE depends on multiple stdlibs, in particular tkinter, which depends on tcl/tk.  To test if the Windows versions work under Bootcamp, run "python -m tkinter" in Command Prompt.  You should see a tk window with text and a click-me button.  If that works, try "python -m turtle".  It should draw and erase a couple of patterns.  If both work, "python -m test".  Then try "python -m idlelib" and report any error messages that appear.
