今天我们来用Pygame画图。
首先下载Pygame第三方库：
在cmd中输入以下命令

pip install pygame

然后上代码（今天没有附件哦）：
首先我们画三个不同的正方形：

import pygame
import sys
from pygame.locals import *
pygame.init()
WHITE = (255,255,255)
BLACK = (0,0,0)
size = whidth,height = 640,150
screen = pygame.display.set_mode(size)
pygame.display.set_caption('drawing')
clock = pygame.time.Clock()
while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            sys.exit()
    screen.fill(WHITE)
    pygame.draw.rect(screen,BLACK,(50,50,150,50),0)
    pygame.draw.rect(screen,BLACK,(250,50,150,50),1)
    pygame.draw.rect(screen,BLACK,(450,50,150,50),10)
    pygame.display.flip()
    clock.tick(10)

效果如下：

然后是一条鱼：

import pygame
import sys
from pygame.locals import *
pygame.init()
WHITE = (255,255,255)
BLACK = (0,0,0)
GREEN = (0,255,0)
points = [(200,75),(300,25),(400,75),(450,25),(450,125),(400,75),(300,125)]
size = whidth,height = 640,200
screen = pygame.display.set_mode(size)
pygame.display.set_caption('drawing')
clock = pygame.time.Clock()
while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            sys.exit()
    screen.fill(WHITE)
    pygame.draw.polygon(screen,GREEN,points,0)
    pygame.display.flip()
    clock.tick(10)

效果如下：

接着：

import pygame
import sys
from pygame.locals import *
pygame.init()
WHITE = (255,255,255)
BLACK = (0,0,0)
GREEN = (0,255,0)
RED = (255,0,0)
BLUE = (0,0,255)
size = whidth,height = 620,480
screen = pygame.display.set_mode(size)
pygame.display.set_caption('drawing')
position = size[0] // 2,size[1] // 2
moving = False
clock = pygame.time.Clock()
while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            sys.exit()
        if event.type == MOUSEBUTTONDOWN:
            if event.button == 1:
                moving = True
        if event.type == MOUSEBUTTONUP:
            if event.button == 1:
                moving = False
    if moving:
        position = pygame.mouse.get_pos()
    screen.fill(WHITE)
    pygame.draw.circle(screen,RED,position,25,1)
    pygame.draw.circle(screen,GREEN,position,75,1)
    pygame.draw.circle(screen,BLUE,position,125,1)
    pygame.display.flip()
    clock.tick(120)

画出了个靶子：

嘿！这个靶子还能移动！：

这里还剩下了两段代码，大家可以把运行结果留言在评论区：
代码1：

import pygame
import sys
from pygame.locals import *
pygame.init()
WHITE = (255,255,255)
BLACK = (0,0,0)
GREEN = (0,255,0)
RED = (255,0,0)
BLUE = (0,0,255)
size = whidth,height = 620,300
screen = pygame.display.set_mode(size)
pygame.display.set_caption('drawing')
position = size[0] // 2,size[1] // 2
clock = pygame.time.Clock()
while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            sys.exit()
    screen.fill(WHITE)
    pygame.draw.ellipse(screen,BLACK,(100,100,440,100),1)
    pygame.draw.ellipse(screen,BLACK,(220,50,200,200),1)
    pygame.display.flip()
    clock.tick(120)

代码2：

import pygame
import sys
from pygame.locals import *
pygame.init()
WHITE = (255,255,255)
BLACK = (0,0,0)
GREEN = (0,255,0)
points = [(200,75),(300,25),(400,75),(450,25),(450,125),(400,75),(300,125)]
size = whidth,height = 640,480
screen = pygame.display.set_mode(size)
pygame.display.set_caption('drawing')
clock = pygame.time.Clock()
while True:
    for event in pygame.event.get():
        if event.type == QUIT:
            sys.exit()
    screen.fill(WHITE)
    pygame.draw.lines(screen,GREEN,1,points,1)
    pygame.draw.line(screen,BLACK,(100,200),(540,250),1)
    pygame.draw.aaline(screen,BLACK,(100,250),(540,300),1)
    pygame.draw.aaline(screen,BLACK,(100,300),(540,350),0)
    pygame.display.flip()
    clock.tick(10)

嗯，今天就到这里了哦！
