How to check whether a variable is a class or not?
oop, python
Solution
Even better: use the `inspect.isclass` function.
>>> import inspect
>>> class X(object):
... pass
...
>>> inspect.isclass(X)
True
>>> x = X()
>>> isinstance(x, X)
True
>>> inspect.isclass(x)
False
Problem
I was wondering how to check whether a variable is a class (not an instance!) or not. I've tried to use the function `isinstance(object, class_or_type_or_tuple)` to do this, but I don't know what type a class would have. For example, in the following code ``` class Foo: pass isinstance(Foo, **???**) # i want to make this return True. ``` I tried to substitute "`class`" with ???, but I realized that `class` is a keyword in python.
