For the following space game using python code I need a code to make the laser shooting cannon in the bottom to move left or right. (right now it is just sitting stationary). What is a possible code to make it move using this code below that I provided? Don't post a wrong answer if you don't know.

from turtle import Turtle, mainloop import random import math class LaserCannon(Turtle): def __init__(self, xmin, xmax, ymin, ymax): super().__init__() self.screen = self.getscreen() self.screen.bgcolor('light green') self.screen.setworldcoordinates(xmin, ymin, xmax, ymax) self.screen.onclick(self.aim, 1) self.screen.onkey(self.shoot, "s") self.screen.onkey(self.quit, 'q') def aim(self, x, y): heading = self.towards(x, y) self.setheading(heading) def shoot(self): Bomb(self.heading(), 5) def quit(self): self.screen.bye() class BoundedTurtle(Turtle): def __init__(self, speed, xmin=-200, xmax=200, ymin=0, ymax=400): super().__init__() self.xmin = xmin self.xmax = xmax self.ymin = ymin self.ymax = ymax self.speed = speed def outOfBounds(self): xpos, ypos = self.position() out = False if xpos < self.xmin or xpos > self.xmax: out = True if ypos < self.ymin or ypos > self.ymax: out = True return out def move(self): self.forward(self.speed) if self.outOfBounds(): self.remove() else: self.getscreen().ontimer(self.move, 200) def remove(self): self.hideturtle() class Bomb(BoundedTurtle): def __init__(self, initHeading, speed): super().__init__(speed) self.initHeading = initHeading self.resizemode('user') self.color('red', 'red') self.shape('circle') self.setheading(initHeading) self.up() self.turtlesize(.75) self.getscreen().ontimer(self.move, 100) def move(self): exploded = False self.forward(self.speed) for i in Alien.getAliens(): if self.distance(i) < 5: i.remove() exploded = True if self.outOfBounds() or exploded: self.remove() else: self.getscreen().ontimer(self.move, 100) def distance(self, other): p1 = self.position() p2 = other.position() a = p1[0] - p2[0] b = p1[1] - p2[1] dist = math.sqrt(a ** 2 + b ** 2) return dist class Alien(BoundedTurtle): alienList = [] @staticmethod # CLASS METHOD: You can call this method with the class name without creating instances of the class  def getAliens(): return [x for x in Alien.alienList if x.alive] def __init__(self, speed, xmin, xmax, ymin, ymax): super().__init__(speed, xmin, xmax, ymin, ymax) self.getscreen().tracer(0) self.up() if 'PurpleAlien.gif' not in self.getscreen().getshapes(): self.getscreen().addshape('PurpleAlien.gif') self.shape('PurpleAlien.gif') self.goto(random.randint(xmin - 1, xmax - 1), ymax - 20) self.setheading(random.randint(250, 290)) self.getscreen().tracer(1) Alien.alientList = [x for x in Alien.alienList if x.alive] Alien.alienList.append(self) self.alive = True self.getscreen().ontimer(self.move, 200) # INSTANCE METHOD: You can call this method, for any instance of the class  def remove(self): self.alive = False self.hideturtle() class AlienInvaders: def __init__(self, xmin, xmax, ymin, ymax): super().__init__() self.xmin = xmin self.xmax = xmax self.ymin = ymin self.ymax = ymax def play(self): self.mainWin = LaserCannon(self.xmin, self.xmax, self.ymin, self.ymax).getscreen() self.mainWin.ontimer(self.addAlien, 1000) self.mainWin.listen() mainloop() def addAlien(self): if len(Alien.getAliens()) < 7: Alien(1, self.xmin, self.xmax, self.ymin, self.ymax) self.mainWin.ontimer(self.addAlien, 1000) game = AlienInvaders(-200, 200, 0, 400) game.play()
