24 Sep Monday 20:00 Python Practice 20.09.21.

Question:
Create a Tank class which have the attributes of:

  • name
  • direction(use ‘up’, ‘down’, ‘left’ or ‘right’)
  • x position and
  • y position

The class also have the following method:

  • move (direction, steps) method can change the x or y position base on the direction and steps. it will also change the direction tank facing. (‘up’ and ‘down’ can change y position while ‘left’ and ‘right’ can change x position)
  • Using __init__() to Initial the tank to make sure it start from x position of 0, y position of 0 and facing up
  •  __str__() method

You need write main program to create tank object from Tank class, you need to use the method of move and use print(tank object) to print out the tank’s current x, y position and its direction after each move.

    class Tank:
    def __init__(self, name, postion=’x’, position=’y’, direction=’up’):
    self.name = name
    self.position = position
    self.direction = direction

    def move(self):
    if position == ‘x’:
    self.direction = ‘left’ and ‘right’
    if position == ‘y’:
    self.direction = ‘up’ and ‘down’

    t1 = Tank(‘Panzerkampfwagen VVI Maus’)
    print(‘tank1 name: %s, position: %s, direction: %s’
    %(t1.name, t1.position, t1.direction))
