Leaf

 This appears to be the basic model for drawing curved shapes with

turtle. We are, effectively, defining mathematical functions.

from turtle import*

Screen().bgcolor('LightYellow2')
my_t = Turtle()
my_t.color('green')
my_t.speed(1)
my_t.pu()
my_t.goto(0, -100)
my_t.pd()

def draw_leaf():
    my_t.begin_fill()
    for i in range(50):
        my_t.forward(1)
        my_t.left(1)

    for j in range(75):
        my_t.forward(2)
        my_t.left(1)


    while my_t.xcor() >= 0:
        my_t.forward(3)
        my_t.left(1)
    my_t.end_fill()

draw_leaf()
done()
