Research direction

Reproduce the supplied BaseClassA/BaseClassB/ClassC multiple-inheritance example and compare its Transcrypt output with CPython. Trace the compiler's handling of inherited init methods, then verify that the generated behavior matches CPython for this example.

Description

IS: bug?

Hi.

I found that a method in the second base class was not called when there was another base class in front of the second one. It seems that the first base class overrides the second one even when the first one has no method

Following is the code I tested:

class BaseClassA:
    def __init__(self, text):
        print('in __init__ in BaseClassA')
        self.text= text
class BaseClassB:
    pass
class ClassC(BaseClassB, BaseClassA):
    pass
def main():
    obj= ClassC('hello')
    print('obj.text= ', obj.text)
if __name__ == '__main__':
    main()

The output in CPython:

in __init__ in BaseClassA
obj.text=  hello

The output in Transcrypt:

obj.text=  None

I think that the first base class should override ONLY WHEN it has a method. It looks like a bug in class inheritance.

Thanks.
