Python初级编程，跟我一步一步学画气球

1.      先画一个圆

import turtle as q

q.circle(50)

q.rt(90)

q.fd(100)

q.lt(90)

q.done()

2.      着色，导入随机模块，随机确定开始画图的坐标点

import turtle as q

import random

q.colormode(255)

x=random.randint(-300,300)

y=random.randint(-300,300)

r=random.randint(0,255)

g=random.randint(0,255)

b=random.randint(0,255)

q.color(r,g,b)

q.up()

q.goto(x,y)

q.down()

q.begin_fill()

q.circle(50)

q.rt(90)

q.fd(100)

q.lt(90)

q.end_fill()

3.把画气球这一段程序定义为函数，庄闲和游戏网然后调用画20个气球

import random

q.speed("fastest")

q.colormode(255)

def qiqiu():

    x=random.randint(-300,300)

    y=random.randint(-300,300)

    r=random.randint(0,255)

    g=random.randint(0,255)

    b=random.randint(0,255)

    radius=random.randint(10,70)

    q.color(r,g,b)

    q.up()

    q .goto(x,y)

    q.down()

    q.begin_fill()

    q.circle(radius)

    q.rt(90)

    q.fd(100)

    q.lt(90)

    q.end_fill()

for i in range(20):

qiqiu()
