Question

Write a class named Taxicab that has three private data members: one that holds the current x-coordinate, one that holds the current y-coordinate, and one that holds the odometer reading (the actual odometer distance driven by the Taxicab, not the Euclidean distance from its starting point). The class should have an init method that takes two parameters and uses them to initialize the coordinates, and also initializes the odometer to zero. The class should have get members for each data member: get_x_coord, get_y_coord, and get_odometer. The class does not need any set methods. It should have a method called move_x that takes a parameter that tells how far the Taxicab should shift left or right. It should have a method called move_y that takes a parameter that tells how far the Taxicab should shift up or down. For example, the Taxicab class might be used as follows:

cab = Taxicab(5, -8)
cab.move_x(3)
cab.move_y(-4)
cab.move_x(-1)
print(cab.get_odometer())

Code must be in python, not C++ or Java.

Please find the answer below, all the details are mentioned in the comments:

#class Taxicab

class Taxicab:

#init method to intialize values

def __init__(self, x_coord, y_coord,odometer = 0):

self.__x_coord=x_coord # private attribute

self.__y_coord=y_coord # private attribute

self.__odometer = 0

#getter methods for all 3 private fileds

def get_x_coord(self):

return self.__x_coord

def get_y_coord(self):

return self.__y_coord

def get_odometer(self):

return self.__odometer

#move_x to increment x_coord

def move_x(self,x_move):

self.__x_coord += x_move

#move_y to increment y_coord

def move_y(self,y_move):

self.__y_coord += y_move

cab = Taxicab(5, -8)

cab.move_x(3)

cab.move_y(-4)

cab.move_x(-1)

print(cab.get_odometer())

Code snippet:

#class Taxicab class Taxicab: #init method to intialize values def __init__(self, x_coord, y_coord, odometer = 0): self._x_coord=x_coord # private attribute self._y_coord=y_coord # private attribute self. __odometer = 0 #getter methods for all 3 private fileds def get_x_coord(self): return self._x_coord def get_y_coord(self): return self._y_coord def get_odometer(self): return self._odometer #move_x to increment x_coord def move_x(self,x_move): self.__x_coord += x_move #move_y to increment y_coord def move_y(self,y_move): self._y_coord += y_move 28 29 30 cab = Taxicab(5, -8) cab.move_x(3) cab.move_y(-4) cab.move_x(-1) print(cab.get_odometer())
