A list is the most primal data type of the Python language. It is used to store different elements under a single name. It is similar to an array in other programming languages with a little difference. While a list can store heterogeneous elements, an array can’t. The elements of the ...
Create and return a list of all possible pairs from values in rs and va lues in ys. T he order of elements is important - all of the pa irs of Is's first element must appear before a ll pairs involving rs's second element; similarly, when pairing with a specific element from rs,...
