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__();"

[ronaldoussoren]

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.
