type("") is of type type, not type string. You can apply the str() function
to it, but this will give you a method with the string instance bound to it:

>>> type("")
<type 'string'>
>>> str(type(""))
"<type 'string'>"
>>> x = str(type("")).upper
>>> x()
"<TYPE 'STRING'>"
>>> x("A banana")
Traceback (innermost last):
  File "<interactive input>", line 1, in ?
TypeError: upper requires exactly 0 arguments; 1 given
