As mentioned in the subject line for a given objec (module or class) 

print (object.__doc__)   works
document.write (object.__doc__)
TypeError" write: () argument must be a str not None

I do get type(object.__doc__) is None

Update: Grrr...indeed the first object in the list had not doc string Now the error mutated to TypeError" must be a str not type

    Cannot reproduce: on my machine, `type(object.__doc__)` gives ``. Do you have a complete example? https://stackoverflow.com/help/mcve – NPE Oct 20 '18 at 22:52
  • What does `print(object.__doc__)` print? `None`? – user2357112 Oct 20 '18 at 22:54

Assuming that by object you don't mean the built-in object class but rather your own class.

For __doc__ to not be None, the class in question has to have a docstring.

Contrast:

>>> class X(object):
...    pass
... 
>>> type(X.__doc__)
<type 'NoneType'>

with:

>>> class Y(object):
...    "Class Y"
... 
>>> type(Y.__doc__)
<type 'str'>
