carmaker and buffmaker mistaken as Turtle's attrubute

Iam trying to build a simple road crossing game using python where the player can pick up buffs and got stuck in a trap. If player picks up a buff then car's movement is going to be slowed. if player got stuck on a trap then player will die.

However when trying to summon the buffs and the traps, python assumed that the buffmaker() and trap_maker() methods as a Turtle attribute Thus raising error. What can I do to fix these problems?

player.py

    STARTING_POSITION = (0, -280)
    MOVE_DISTANCE = 10
    FINISH_LINE_Y = 280


class Player(Turtle):
    def __init__(self):
        super().__init__()
        self.shape("classic")
        self.pu()
        self.go_to_start()
        self.setheading(90)
        self.fd(MOVE_DISTANCE)
def move_fd(self):
        self.setheading(90)
        self.fd(MOVE_DISTANCE)

    def move_bk(self):
        self.setheading(90)
        self.bk(MOVE_DISTANCE)

    def move_left(self):
        self.setheading(180)
        self.fd(MOVE_DISTANCE)

    def move_right(self):
        self.setheading(0)
        self.fd(MOVE_DISTANCE)

    def at_finish_line(self):
        if self.ycor() >= 300:
            return True
        else:
            False

    def go_to_start(self):
        self.goto(STARTING_POSITION)```

        trap.pu()
        trap.goto(random.randint(-100, 100), random.randint(-200, 250))
        self.bombs.append(trap)```

buff.py

from turtle import Turtle
import random

class Trap(Turtle):
    def __init__(self):
        super().__init__()
        self.hideturtle()
        self.screen.register_shape("Gifs/stopwatch.gif")
        self.buffs=[]


    def buffmaker(self):
        buff = Turtle()
        buff.shape("Gifs/stopwatch.gif")
        buff.pu()
        buff.goto(random.randint(-100, 100), random.randint(-200, 250))
        self.bombs.append(buff)

carmanager.py

from turtle import Turtle
import random
COLORS = ["red", "orange", "yellow", "green", "blue", "purple"]
STARTING_MOVE_DISTANCE = 2
MOVE_INCREMENT = 2


class CarManager(Turtle):
    def __init__(self):
        super().__init__()
        self.hideturtle()
        self.cars=[]

    def carmaker(self):
        if random.randint(1, 24)==1:
            car = Turtle()
            car.shape("square")
            car.pu()
            car.color(random.choice(COLORS))
            car.setheading(180)
            car.shapesize(1, 2)
            car.goto(300, random.randint(-200, 250))
            self.cars.append(car)

    def car_move(self, multiplier, buff):
        for cars in self.cars:
            cars.fd(STARTING_MOVE_DISTANCE + ((0.5*multiplier)*MOVE_INCREMENT )- (0.25*buff))

The primary issue I see is that the class Buff isn't defined, by mistake it's also called Trap and appends to bombs instead of buffs:

buff.py

from turtle import Turtle
import random

class Trap(Turtle):
    def __init__(self):
        super().__init__()
        self.hideturtle()
        self.screen.register_shape("Gifs/stopwatch.gif")
        self.buffs=[]

    def buffmaker(self):
        buff = Turtle()
        buff.shape("Gifs/stopwatch.gif")
        buff.pu()
        buff.goto(random.randint(-100, 100), random.randint(-200, 250))
        self.bombs.append(buff)

Looks like a copy and paste error. Also this function is slightly broken:

def at_finish_line(self):
    if self.ycor() >= 300:
        return True
    else:
        False

The simple fix is:

def at_finish_line(self):
    if self.ycor() >= 300:
        return True
    else:
        return False

The better fix is:

def at_finish_line(self):
    return self.ycor() >= 300:
