He could have done it in various other ways too:

eg.
lambda : all(print('Hello lambda world!'), sys.exit() )

Well, now I am curious as to why the "all" form evaluates BOTH
elements. Apparently it does not apply the short-circuit logic we have
been discussing, or it would stop evaluating after the print statement
return.  Why is that?

Because I didn't really think the example through properly.
I just grabbed the first thing I could think of that would
evaluate both functions... As Cameron has shown, a much more
elegant solution is just to use a tuple as the body of
the lambda.

That's effectively what's happening indside the all()/any()
calls.
