jack -复习for循环，学习随机数

# 用变量，for循环画一个五角星 in2
# 3rt Ins
import random
import turtle
changdu=100
jiaodu=144
turtle.speed(0)
for r in range(100):
    x = random.randint(-350, 350)
    y = random.randint(-350, 350)
    turtle.penup()
    turtle.goto(x,y)
    turtle.pendown()
    for z in range(5):
        turtle.forward(changdu)
        turtle.right(jiaodu)
# pendown
turtle.done()

import random
# 产生0-1的随机小数  random随机的意思
a = random.random()
print(a)
# 产生随机整数
b = random.randint(1,100)
print(b + a)
a = 1
b = 2
print(123-b)
