What does use of BeautifulSoup module in Python?

Question

The type() builtin according to python docs, returns a "type object".
http://docs.python.org/2/library/types.html

And in this module is bunch of what I assume are "type objects". Is this correct?
http://docs.python.org/2/library/functions.html#type

And type(), aside from being used in as an alternative to a class statement to create a new type, really just returns the object class, doesn't it?

>>> import types
>>> a = type(1)
>>> b = (1).__class__
>>> c = int
>>> d = types.IntType
>>> a is b is c is d
True
>>> 

If type() didn't exist would it be much more of a matter than the following?:

def type(x): 
 return x.__class__

What is the purpose of type()?
What exactly is a "type object"? Is it a "class"?
What is the purpose of the types module?

I understand the purpose of isinstance and why it's recommended over something like (type(1) is int). Because isinstance will also return True if the object is an instance of a subclass.

>>> class xint(int):
 def __init__(self):
 pass

>>> x = xint()
>>> type(x) is int
False
>>> isinstance(x, int)
True
>>>

BeautifulSoup is a python library which make it very easy to parse html or xml files.

Typically , when you have a xml file, you would want to parse it in a few way like
- Getting all child elements tags
- Getting children at nth level
- Getting parent element of a XML tag

Beautiful soup offers a very well defined and intuitive API to do all this and more.
