Re: Why would I use inspect.isclass()?

It's me wrote:
I guess another example would be an assert on the type of argument:
def foo(someClass):
    assert inspect.isclass(someClass)
    # rest of code
But that would always fail!  (I just tried it).
Are you sure you haven't pass an instance instead of a class?  Remember, 
classes are also objects in Python:

>>> import inspect
>>> class A: pass
...
>>> def foo(a): assert inspect.isclass(a)
...
>>> foo(A)
>>>
Works fine and makes sense, no?  Of course, if I pass an instance 
instead of a class it would fail:

>>> myA = A()
>>> foo(myA)
Traceback (most recent call last):
  File "<stdin>", line 1, in ?
  File "<stdin>", line 1, in foo
AssertionError
Maybe your question is in what situations passing a class can be useful? 
   There's many examples and once you're used to that capability it can 
be powerful.  One simple example could be the generation of 
documentation; since you usually want to doc your classes, not 
instances.  So it would make sense to do something like:

def writeHtmlDoc(file, someClass): ...
