Complete the function definition. from graphics import * import random def randomPoints (n, win) "Here n is a positive integer, and win is a GraphWin. Draw n randomly placed Points in win so all x and y coordinates could be any integers in the range 0-100, including 0 and 100. For example, if n is 4, you might draw Point(22, 79), Point(86, 0), Point(100, 55), Point(17, 90)
