使用Python的turtle模块画出简单的柱状图

import turtle
heights = [856, 420,360,260,205]
def main():
    t = turtle.Turtle()
    t.hideturtle()
    for i in range(5):
        drawFilledRectangle(t,-200+(76*i),0,76,heights[i]/4,"black","light blue")
    displayText(t)
def drawFilledRectangle(t,x,y,w,h,colorP="black",colorF="white"):
    t.pencolor(colorP)
    t.fillcolor(colorF)
    t.up()
    t.goto(x,y)
    t.down()
    t.begin_fill()
    t.goto(x+w,y)
    t.goto(x+w,y+h)
    t.goto(x,y+h)
    t.goto(x,y)
    t.end_fill()
def displayText(t):
    languages = ["haha1", "haha2", "haha3", "haha4", "haha5"]
    t.pencolor("blue")
    t.up()
    for i in range(5):
        t.goto((-162+76*i),heights[i] / 4)
        t.write(str(heights[i]),align="center",font=("Arial",10,"normal"))
        t.goto((-162+76*i),10)
        t.write(languages[i],align="center",font=("Arial",10,"normal"))
        t.goto(-200,-25)
        t.write("haha 统计图",font=("Arial",10,"normal"))
        t.goto(-200,-45)
        t.write(‘(哈哈哈哈哈啊哈哈)‘,font=("Arial",10,"normal"))
main()
