Explanation:
class Taxicab():
def __init__(self, x, y):
self.x_coordinate = x
self.y_coordinate = y
self.odometer = 0
def get_x_coord(self):
return self.x_coordinate
def get_y_coord(self):
return self.y_coordinate
def get_odometer(self):
return self.odometer
def move_x(self, distance):
self.x_coordinate += distance
# add the absolute distance to odometer
self.odometer += abs(distance)
def move_y(self, distance):
self.y_coordinate += distance
# add the absolute distance to odometer
self.odometer += abs(distance)
cab = Taxicab(5,-8)
cab.move_x(3)
cab.move_y(-4)
cab.move_x(-1)
print(cab.odometer) # will print 8 3+4+1 = 8
I am assuming you are talking about programming
