trunk.pendown()
trunk.forward(50)
trunk.right(90)
trunk.forward(100)
trunk.right(90)
trunk.forward(50)

# 画树枝

branch.color('green')
branch.pensize(5)
branch.penup()
branch.setposition(0, -100)
branch.pendown()
branch.right(90)
branch.forward(100)
branch.right(180)

# 画树叶
for i in range(5):
    branch.right(40)
    branch.forward(20)
    branch.right(140)
