Why " ".some_string is often used ?

You can always use the __len__ attribute in this specific case.

And now for the hack value:

class MyList(list):
    import new as _new, __builtin__
    def __getattr__(self, attr):
        try:
            return self._new.instancemethod( \
                   getattr(self.__builtin__, attr), \
                   self, \
                   None)
        except AttributeError:
            raise AttributeError, \
                  "there is no '%s' builtin" % attr

allowing:

>>> a=MyList()
>>> a.append(12)
>>> a.append(24)
>>> a.len()
2
>>> a.min()
12
>>> a.max()
24

It works for all builtins that can take a list as a first argument.
Of course it should not be taken seriously :)
