Re: Add methods to string objects.

You can even get closer, but it is NOT recommended

class foostr(str):
def plural (self):
if self.value[-1] in "sz":
return self.value + "es"
else:
return self.value + "s"


#ugly hack
setattr(__builtins__, "str", foostr)

print str("apple").plural()

# this however does not work
# print "apple".plural()

.
