Question

The four compass points can be abbreviated by single-letter strings as "N", "E", "S", and "W". Write a function turn_clockwise that takes one of these four compass points as its parameter, and returns the next compass point in the clockwise direction. Here are some tests that should pass:
test(turn_clockwise("N") == "E")
test(turn_clockwise("W") == "N")
You might ask "What if the argument to the function is some other value?" For all other
cases, the function should return the value None:
test(turn_clockwise(42) == None)
test(turn_clockwise("rubbish") == None)

Answer 1

Answer:

The program code is written in the explanation.

Explanation:

def turn_clockwise(d):

if d=="N":

return "E"

elif d=="E":

return "S"

elif d=="S":

return "W"

elif d=="W":

return "N"

else:

return "None"

Output:
