__repr__ Does not honor subclasses

[darricktheprogrammer]

A common pattern for me is to subclass Box to get all of its features, but with a type custom to the application. Because box hard codes the types in the __repr__ method for each class, failed test reports and print debugging is often confusing. Where I am expecting to see MyCustomBox(...), instead just Box(...) is printed which makes me think I incorrectly instantiated an object.

This can be fixed by using type(self).__name__ instead of hard coding each type name within the class. It also has the benefit that duplicate code could be removed from some builtin Box subclasses, such as SBox because it would be dynamically generated from the base Box class.

Example:

from box import Box


class MyBox(Box):
    pass


class ActuallyMyBox(Box):
    def __repr__(self):
        return f"{type(self).__name__}({self})"


b1 = MyBox(a=1)
b2 = ActuallyMyBox(b=2)
print(repr(b1))
print(repr(b2))

>>> Box({'a': 1})
>>> ActuallyMyBox({'b': 2})
