Inverting a Python dictionary with zip(): swapping keys and values
The zip function transforms two lists of the same length into a single list by "pairing up" corresponding elements into a tuple. Here, we use "zip" to "invert" a dictionary, by swapping its keys for its values and vice-versa. Note that since all the keys in a dictionary must obviously be different, this makes sense only if no two values are equal.
