It's actually enough to provide a single list to Zip[]. This makes it a shorter alternative to Sequence[] when all you want is to traverse a list. For example, <code>Zip[a^2, a, listOfNumbers]</code> is much shorter than <code>Sequence[Element[listOfNumbers, a]^2, a, 1, Length[listOfNumbers]]</code> (albeit in this case it's easier to just do <code>listOfNumbers^2</code>.) | It's actually enough to provide a single list to Zip[].

It's actually enough to provide a single list to Zip[]. This makes it a shorter alternative to Sequence[] when all you want is to traverse a list. For example, Zip[a^2, a, listOfNumbers] is much shorter than Sequence[Element[listOfNumbers, a]^2, a, 1, Length[listOfNumbers]] (albeit in this case it's easier to just do listOfNumbers^2.)
Hint: Zip[] is similar to a construct known as "map" in other programming languages.
