How to check if class instance exists in a list of class instance objects?

[volcano63]

instances of classes and instances of objects???

Classes in Python are objects too

[buran]

Of course everything is an object, no doubt about that!!! "
That's exactly why I don't get the difference you make between instances of classes and instances of objects...

Does "object of un-instantiated class" sounds better? If that is still unclear

Output:
In [31]: type(list().__class__)
Out[31]: type

In [32]: type(dict().__class__)
Out[32]: type

In [33]: type('abc'.__class__)
Out[33]: type

Classes itself are objects of type .... type, which is a trinity of function, metaclass and class factory.

Even if object is un-hashable, the class of that object will be always hashable (unless you implement some crazy hack that will make it unhashable - if that is possible). Again, look at my code: I was not saving objects in a set - I was saving classes

PS Maybe, a little demonstration will help

Output:
In [37]: class A:
    ...:     def __init__(self, name):
    ...:         self.name = name
    ...:         

In [38]: set([A('volcano63').__class__, A('buran').__class__, A('sonicblind').__class__])
Out[38]: {__main__.A}

Yes, now I see what you mean
