How to terminate a main script?

[Helmut Jarausch]

Hi,

I'm still looking for an elegant and clear means to
terminate the main script in Python.

Unfortunately, Python doesn't allow a 'return'
instruction in the main script.

Using sys.exit(0) produces an error
message which looks dangerous to an
uninitiated user.

The same is true for an exception.

And setting a 'flag' and testing
at several place for 'fall through'
is ugly and error-prone.

So what is a good choice?

Many thanks for a hint,
