[Tutor] Halting execution

[Ertl, John]

For this case, just wanting to stop the code for testing, using a short
statement as the arg is not only OK it is an example in the doc.

exit(	[arg])
Exit from Python. ......  In particular, sys.exit("some error message") is a
quick way to exit a program when an error occurs. 

I agree I should be a bit more careful about giving examples that are quick
fixes as opposed to best practice.

It would be similar to Perl's die() commmand. But no, in Python the 
argument is the error status of your script.

You'd have to do something like

def exitnow(arg):
     print arg
     #maybe sys has not been imported
     import sys
     sys.exit(1)
