Generating and Swapping Key-Value-Pairs in Dictionary

Create a function that takes:

1. A list of keys.
2. A list of values (same size).
3. True, if key and value should be swapped, else False.

The function returns the constructed dict. Empty lists return an empty dict.

Examples

swap_d([1, 2, 3], ["one", "two", "three"], False)
➞ { 1: "one", 2: "two", 3: "three" }

swap_d([1, 2, 3], ["one", "two", "three"], True)
➞ { "one": 1, "two": 2, "three": 3 }

swap_d(["Paris", 3, 4.5], ["France", "is odd", "is half of 9"], True)
➞ { "France": "Paris", "is odd": 3, "is half of 9": 4.5 }

Notes

• To make it simple, use only hashable (= immutable) keys.
• To make it simple, use only unique keys.
