Actually, there is an execute permission bit on Windows, but only on
NTFS; Cygwin uses that to "fake" Posix-style x bit.  But Emacs (the
native Windows build of it) does not use these NTFS features, and
frankly, I'm not sure it's worth the hassle (and there _is_ a very
real hassle, because mapping Posix rwx bits into NTFS ACLs is a
non-trivial job).

But I digress.  The real question in this bug report is why did the
OP need a Python script to appear as executable to Emacs.
