You are making a very common mistake.  No matter how hard you try,
you just can't type the names of executable program files at the 
Python >>> prompt and expect them to work.

Program files, i.e. *.exe under Windows, have to be run from the 
Start, Run dialog, by double-clicking the program file, or from 
the MS-DOS command prompt.  

Not that it's impossible under Python, just silly:

    import os
    os.system("tclsh83")

Note that THIS won't work if the PATH environment variable does not
include the path to the tclsh83.exe program file.

Windows programmers MUST learn to use the MS-DOS prompt, even if you
rarely visit it.

Is this a FAQ?  (I haven't looked.)  If not it should be.
