Inner Class in Python: A Simple Example In Python, inner classes or nested classes can be defined inside the scope of another class. These inner classes can access all the members of their enclosing class. Proper indentation is crucial when defining inner classes. Typically, each inner class is...
Possibly related to python/cpython#97002 which was closed with the comment "I finally found the root issue, which is that a poorly-timed GC collection just before tracing the resumption of a generator can cause two duplicate frame objects to be created, which corrupts the VM's internal state...
