Python 使用turtle模块绘制统计柱状图

【题目】使用turtle模块绘制词频统计结果，其中词频数据 wordFrequency = {"the":104, "a":63, "to":42, "of":42, "Kevin":36, "he":32, "you":28, "and":28, "is":27, "i":26}
以柱状图的形式展示统计结果。

今天在问答频道刷到的题，简单做了一遍画了两张图，分享给turtle入门者： 

import turtle
import time
t = turtle.Pen()

t.color("red")
t.pensize(3)
t.speed(0)

def Goto(x,y):
    t.penup()
    t.goto(x,y)
    t.pendown()
              
def rect(x,y,h,w=45):
    Goto(x,y)
    for i in range(2):
        t.forward(w)
        t.left(90)
        t.forward(h)
        t.left(90)
        t.fillcolor('red')

def main():
    start_x , start_y = -320, -200
    Goto(start_x , start_y)
    t.forward(630)
    for i,d in enumerate(wordFrequency.items()):
        rect(start_x + i*65, start_y ,d[1]*4 )
        tx = t.xcor()
        Goto(tx+(6-len(d[0]))*4, t.ycor()-25)
        t.write(d[0], font=('Arial',14,'normal'))
        Goto(tx + (8 if d[1]>100 else 12), t.ycor()+d[1]*4+30)
        t.write(d[1], font=('Arial',14,'normal'))

wordFrequency = {"the":104,"a":63,"to":42,"of":42,"Kevin":36,"he":32,"you":28,"and":28,"is":27,"i":26}
main()
time.sleep(3)

# 排序后再画
wordFrequency = { i:wordFrequency[i] for i in sorted(wordFrequency) }
t.clear()
main()

t.hideturtle()
turtle.mainloop()

单词排序后，再画一次：
