[issue9212] dict_keys purports to implement the Set ABC, but is missing the isdisjoint method

[Daniel Urban]

Daniel Urban <urban.dani+py at gmail.com> added the comment:

The attached patch adds the isdisjoint method to dict_keys and dict_items.
Pseudocode for the method:

def isdisjoint(self, other):
    if self is other:
        if len(self) == 0:
            return True
        else:
            return False
    else:
        for item in other:
            if item in self:
                return False
        return True
