Working
In the given code, d is a dictionary that has tuples (1,2) and (2,3) as keys mapped to their respective values 1 and 21. When we access d[1, 2], Python interprets (1,2) as a tuple and looks for this tuple as a key in dictionary d. Therefore, it retrieves the value associated with the key (1,2), which is 1.
