If you don't want the code to be available outside the module (i.e. you
just run it), you can try something like:


a=123

def b(c, d):
    return c+d

print b(a, 456)

# Delete the things you've finished with
del a
del b

# Add this if you want to try to prevent
# it being imported. Note that sys.exit
# throws an exception, though, which can
# be caught.
sys.exit()
