How do I exit gracefully from a Python script?

Follow this pattern:

try:

    print 'A'

    sys.exit()

    print 'B'

except SystemExit:

    sys.stdout.flush()

In this example, 'A" is printed, but 'B' is not

How do I manage exceptions or errors ?

Follow this pattern:

try:

    print 'A'

    raise RuntimeError('Please open a window')

except RuntimeError as err:

    DialogDisplayer().showMessageDialog(str(err))

except SystemExit:

    sys.stdout.flush()

You can define your own exceptions or reuse built-in exceptions.
