Question

I am writing a small app and I need to quit the program multiple number of times.

Should I use:

sys.stderr.write('Ok quitting')
sys.exit(1)

Or should I just do a:

print 'Error!'
sys.exit(1)

Which is better and why? Note that I need to do this a lot. The program should completely quit.

Answer 1

sys.exit('Error!')

Note from the docs:

If another type of object is passed,
None is equivalent to passing zero,
and any other object is printed to
sys.stderr and results in an exit code
of 1. In particular, sys.exit(“some
error message”) is a quick way to exit
a program when an error occurs.
