Re: Re: Have existing python script file that I want to execute from within a cherrypy web site/page. How can this be done 100% native to cherrypy?

1) don't use os module to spawn subprocesses, just have a function in those
modules, import it and call it then.
2) you probably wrote scripts in a manner/syntax, which is incompatible
with Python 3 and run CherryPy under Python 3. Or maybe just a way you run
scripts is different when you spawn subprocesses. Anyway, I'd recommend you
to not use subprocesses and do normal direct imports.
To mitigate cross python compatibility problems I strongly recommend you
writing scripts using syntax, which works in both or completely switch to
Python 3.
Look for a package distribution called "six", it may provide you some
helpers for cross compat.
