Is there a Data Type in Python which cannot be typecast in string -

-

lets 'a' of type (which want know!)

doing thing like:

b = str(a)

this should favorably raise typeerror

there no builtin python class raises typeerror str, define custom class:

class foo(object):     def __str__(self):         raise typeerror('can not stringified')   foo = foo() b = str(foo)

raises typeerror.
