I make no claims about the following code; it is merely presented for
examination :-)
8< --- namemain.py -----------
# code used both in import mode and script mode
def greet(whom):
print "Hello, %s" % whom
if __name__ == "__main__":
# code used only in script mode
import sys, namemain
tgt = sys.argv[1]
greet(tgt)
namemain.farewell(tgt)

# code used only in import mode
def farewell(whom):
print "Goodbye, %s" % whom
