Of course you don't mean you want another python interpreter to fire up 
and run the other script?

Here is an example of the way to do what you are suggesting:

# mod1.py

def doit(param):
   if not param % 37:
     raise ValueError, 'Why u want to do dat?'
   else:
     print 'All right!'
   return 'Value is: %s' % param

# end of mod1.py


# mod2.py

import mod1

print mod1.doit(20)
print
print mod1.doit(30)
print
try:
   print mod1.doit(37)
except ValueError:
   print 'Gracefully handling 37....'
   print
print mod1.doit(37)

# end of mod2
