You can't quite do that, but you can get close. You can define your own
class which inherits from str, and then create objects of that class. For
example:

class myString (str):
def __init__ (self, value):
self.value = value

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

foo = myString("foo")
bar = myString("bar")
baz = myString("baz")

print foo.plural(), bar.plural(), baz.plural() # my defined method
print foo.capitalize() # inherited from base class
.
