dict class override: how access parent values?

[Andrey]

I'm try override dict class for way that compatible with standart dict class. How i can get access to parent dict attribute if i override getitem method?

1 2 3 4

class CSJSON(dict):     def __getitem__(self, Key : str):        Key = Key + 'zzz' # sample of key modification for app use        return(super()[Key])

Then i faced error:

Error:
'super' object is not subscriptable.

If i'm use self[Key] - then i get infinite recursive call of getitem.

class CSJSON(dict):     def __setitem__(self, key : str, value : all):        return super().__setitem__(key+'zzz', value)       def __getitem__(self, key : str):        return super().__getitem__(key+'zzz')   x = CSJSON() x['Hi'] = "Hola" x['Bye'] = 'Adios' print(*x.keys(), x['Hi'])

Output:
Hizzz Byezzz Hola
