How to execute a file with (---x--x--x) Permissions and I am not the owner?

The problem is, I think, that the interpreter itself has to open and
read in the files to execute them.  Executing a proper binary is done at
the OS level itself in the binary loader, so it doesn't require a
process to open a file, read it, etc.

So these Python scripts?  Have to be readable.  If you don't want them
readable, you should do something like compile them to bytecode and make
those files readable (after stripping all doc strings, etc.) which still
won't quite do what you want, but will be better than what you've got.
