[New-bugs-announce] [issue12370] Use of super overwrites use of __class__ in class namespace

[Michael Foord]

New submission from Michael Foord <michael at voidspace.org.uk>:

In Python 3 the following code prints "False" because the use of super() has caused the __class__ descriptor to be omitted from the class namespace. Remove the use of super and it prints "True".


class X(object):
    
    def __init__(self):
        super().__init__()
    
    @property
    def __class__(self):
        return int
        
print (isinstance(X(), int))
