[Tutor] Returning multiple values from a script

[Hans Dushanthakumar]

Yes I agree that it'd be cleaner to import the second script and call
it.

The reason I'm keen to find a alternate method is that I have a whole
lot of scripts that were designed to run only as standalone scripts. ie
each of these scripts is not a "function" that I could just call from
another script. They are all of the format:

1) Test.py
-------
import sys

sys.exit(5)


Now I'm trying to write a master script that'd run each one of these
scripts. I'm sure it would have been a lot easier if the scripts were of
the following format. Unfortunately they are not.:

Test.py
-------
import sys

Def test():
    return(5, "Junk")

if __name__ == __main__:
   test()


Well if there is no other way I think I'll have to alter all the scripts
to be of the above format. Just wondering if anyone has any suggestions
...

Cheers
Hans

Is there a reason why you have to call the second test.py using
os.system()? I would write it to be imported and called.

test.py
------

def findR():
   return 7, 'Hans'


script1.py
---------

import test

res = test.findR()
print res
