In Python, a class is just an object, so the only limit on how many
classes the interpreter can handle simultaneously is available memory.

However, if you have deeply nested inheritance graphs then you could
start to see performance issues on method calls, since the entire
inheritance graph potentially has to be traversed in order to find the
method.
