https://docs.python.org/3/reference/datamodel.html#object.__init__ "no non-None value may be returned by __init__();" should read "no non-None value may *not* be returned by __init__();" |

The text appears to be correct as it is. What is says is that __init__ must not return any value other than None and that is correct, you will get an exception when you return a value that is not None. >>> class C(): ... def __init__(self): return 42 ... >>> >>> C() Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: __init__() should return None, not 'int' >>> The text is basically a language-lawyer way of stating that __init__ should return by either running of the end of the method, or by using a bare return statement. |

Sorry, I'm going mad, misread it. |
