  • operator.itemgetter(item[, args...])

    Return a callable object that fetches item from its operand using the
    operand’s __getitem__() method. If multiple items are specified,
    returns a tuple of lookup values. Equivalent to:


    def itemgetter(*items):
        if len(items) == 1:
            item = items[0]
            def g(obj):
                return obj[item]
        else:
            def g(obj):
                return tuple(obj[item] for item in items)
        return g
