Switch Keys to Values
You are given a dictionary, where keys and values are strings. Your function should return a dictionary as well, where keys and values from input dictionary are switched: input keys become output values and vice versa. Looks easy? It is so! The only thing left to mention: the values in the result dictionary should be sets (so the input key(s) - the element(s) of the set). Good luck!
Input: A dictionary.
Output: A dictionary.
Examples:
assert switch_dict({"rouses": "red", "car": "red", "sky": "blue"}) == {
"red": {"car", "rouses"},
"blue": {"sky"},
}
assert switch_dict({"1": "one", "2": "two", "3": "one", "4": "two"}) == {
"one": {"1", "3"},
"two": {"2", "4"},
}
assert switch_dict({"a": "b", "b": "c", "c": "a"}) == {
"b": {"a"},
"c": {"b"},
"a": {"c"},
}
