Question

Python

Write a class bug that models a bug moving along a horizontal line. The bug moves either to the right to left. Initially, the bug moves to the right, but it can turn to change its direction. In each move, its position changes by one unit in the current direction. Provide a constructor

def__init__(self, initial position)

and methods

. def turn(self)

. def move(self

. def getposition(self)

Sample usage:

bugsy = bug(10)

bugsy.move() # Now the position is 11

bugsy.turn()

bugsy.move() # Now the position is 10

Answer 1

class Bug:
    def __init__(self, initialPos):
        self.position = initialPos
        self.direction = 1

    def turn(self):
        self.direction *= -1

    def move(self):
        self.position += self.direction
        print("Now the position is " + str(self.position))
        return self.position

    def getPosition(self):
        return self.position


bugsy = Bug(10)
bugsy.move()  # Now the position is 11
bugsy.turn()
bugsy.move()  # Now the position is 10
