I tried to draw Bart Simpson through turtle Python. I almost made it but when it draws around the mouth part, the yellow does not fill in. I could not solve it by myself..import turtlescreen = turtle.Screen()screen.bgcolor('lightblue')t = turtle.Turtle()def bart_face():    t.speed(0)    t.penup()    t.goto(-400, -400)    t.pendown()    t.color("black", "yellow")    t.begin_fill()    t.left(85)    for q in range(180):        t.left(0.05)        t.forward(1)    t.left(90)    for x in range(210):        t.forward(1)        t.right(1)    t.penup()    t.left(190)    t.forward(30)    t.pendown()    t.right(60)    t.forward(600)    # bart hair line    t.right(127)    t.forward(96)    t.left(103)    t.forward(100)    t.right(140)    for i in range(1, 10):        t.forward(100)        t.left(135)        t.forward(100)        t.right(135)    t.right(20)    t.forward(100)    t.right(5)    t.forward(30)    t.right(3)    t.forward(200)    t.left(3)    t.forward(50)    t.right(-40)    for y in range(70):        t.forward(0.5)        t.right(0.5)       t.end_fill()    def bart_eyes():        # bart right eye        t.left(180)        t.color("black", "white")        t.begin_fill()        t.right(-40)        t.circle(120)        t.end_fill()        t.penup()        t.left(90)        t.forward(120)        t.pendown()        t.color("black")        t.begin_fill()        t.circle(10)        t.end_fill()        # the left eye        t.penup()        t.right(65)        t.forward(260)        t.pendown()        t.color("black", "white")        t.begin_fill()        t.left(40)        t.circle(120)        t.end_fill()        t.penup()        t.left(90)        t.forward(120)        t.pendown()        t.color("black")        t.begin_fill()        t.circle(10)        t.end_fill()                      bart_eyes()    t.penup()    t.right(-45)    t.forward(120)    t.pendown()    def bart_nose():                t.color("black", "yellow")        t.begin_fill()        t.left(25)        t.forward(150)        for z in range(150):            t.forward(1)            t.right(1)        t.right(30)        for f in range(1, 10):            t.forward(11)            t.right(0.5)        t.end_fill()            bart_nose()    t.color("black", "yellow")    t.begin_fill()    t.penup()    t.right(174.5)    t.forward(110)    t.pendown()    for a in range(1, 5):        t.right(87)        t.forward(25)        t.left(90)    t.right(90)    t.end_fill()    for b in range(50):        t.forward(1)        t.right(1)    t.right(50)    for c in range(1, 30):        t.right(0.5)        t.forward(15)    t.right(140)    for d in range(40):        t.forward(1)        t.right(1)    t.left(180)    for e in range(90):        t.forward(1)        t.left(1)    t.end_fill()    # neck part    t.color("black", "yellow")    t.begin_fill()    t.penup()    t.left(104.5)    t.forward(200)    t.pendown()    t.right(90)    for g in range(60):        t.forward(1.4)        t.right(0.9)    for h in range(40):        t.forward(1.2)        t.right(0.3)    for i in range(100):        t.forward(2)        t.left(0.5)    t.right(85)    for j in range(157):        t.forward(2)        t.right(0.1)    t.right(76)    t.forward(20)    t.end_fill()bart_face()turtle.done()
