# Sample
mystr = 'Commander, we have received a stress signal from Gul
Dukat'
print 'Original Version : %s' % (mystr)
print 'Shortened Version 1: %s' % (ShortStr(mystr).shorten())
print 'Shortened Version 2: %s' % (ShortStr(mystr).shorten
(length=10, etc=' [more]'))
Output:
Original Version : Commander, we have received a stress signal from
Gul Dukat
Shortened Version 1: Commander, we have re ..
Shortened Version 2: Commander, [more]
And the reason of the subclassing of "str" is so you can do something
like this: ShortStr(mystr).lower() --> commander, we have received a
stress signal from gul dukat
