[=?GB2312?B?uqvP3Ma9?=]

Hi,all.For example,I want learn build-in function TYPE,do help(type)
and get message as following:

Help on class type in module __builtin__:

class type(object)
 |  type(object) -> the object's type
 |  type(name, bases, dict) -> a new type
 |
 |  Methods defined here:
 |
 |  __call__(...)
 |      x.__call__(...) <==> x(...)
 |
 |  __cmp__(...)
 |      x.__cmp__(y) <==> cmp(x,y)
 |
 |  __delattr__(...)
 |      x.__delattr__('name') <==> del x.name
 |
 |  __getattribute__(...)
 |      x.__getattribute__('name') <==> x.name
 |
 |  __hash__(...)
 |      x.__hash__() <==> hash(x)
......
Have TYPE defined these methods?
What relation with __call__,__cam__ etc?
