1.学习目的

python库很多，所以我们要在空闲之余学习我们没有遇到的库，就比如turtle和分词库

2.实验

2.1实验一

2.2实验二

3.实验代码及结果

import turtle as t

ls = [69,292,33,131,61,254]
X_len = 400
Y_len = 300
x0 = -200
y0 = -100

t.penup()
# 前往目标点
t.goto(x0,y0)
t.pendown()

t.fd(X_len)
# 回到目标起点
t.fd(-X_len)
# 画笔方向设置为90°
t.seth(90)
t.fd(Y_len)

t.pencolor('red')
t.pensize(5)
for i in range(0,len(ls)):
  t.penup()
  # -100 Y轴0点
  t.goto(x0+(i+1)*50,-100)
  t.seth(90)
  t.pendown()
  t.fd(ls[i])

#  获取屏幕信息
screen = t.getscreen()
