08-02-03 Sets - set iteration
Remove the smallest element from the set, s. If the set is empty, it remains empty.
if len(s) != 0 : [Tab Key]min = None [Tab Key]for e in s : [Tab Key][Tab Key]if min == None or e < min : [Tab Key][Tab Key][Tab Key]min = e [Tab Key]s.remove(min)
Remove the smallest element from the set, s. Assume the set is not empty.
min = None for e in s : [Tab Key]if min == None or e < min : [Tab Key][Tab Key]min = e s.remove(min)
iven a set, weights, and an integer desired_weight, remove the element of the set that is closest to desired_weight (the closest element can be less than, equal to OR GREATER THAN desired_weight), and assign it to the variable actual_weight. For example, if weights is (12, 19, 6, 14, 22, 7) and desired_weight is 18, then the resulting set would be (12, 6, 14, 22, 7) and actual_weight would be 19. If there is a tie, the element LESS THAN desired_weight is to be chosen. Thus if the set is (2, 4, 6, 8, 10) and desired_weight is 7, the value chosen would be 6, not 8. Assume there is at least one value in the set.
actual_weight = None for e in weights : [Tab Key]if actual_weight == None or (abs(e - desired_weight) < abs(actual_weight - desired_weight)) or (abs(e - desired_weight) == abs(actual_weight - desired_weight) and e < desired_weight) : [Tab Key][Tab Key]actual_weight = e weights.remove(actual_weight)
