1.打印文字

import sys

import pygame
from pygame.locals import  *
white =255,255,255;
blue=0,0,200
pygame.init()
screen=pygame.display.set_mode((600,500))
myfont=pygame.font.Font(None,60)
textImage=myfont.render("Hello Pygame",True,white)
while True:
    for event in pygame.event.get():
        if event.type in (QUIT,KEYDOWN):
            sys.exit()
        screen.fill(blue)
        screen.blit(textImage,(100,100))
        pygame.display.update()

2.绘制圆形

    for event in pygame.event.get():
        if event.type in (QUIT,KEYDOWN):
            sys.exit()
        screen.fill((0,0,200))

        #draw a circle
        color =255,255,0
        posotion=300,250
        radius=100
        width=10
        pygame.draw.circle(screen,color,posotion,radius,width)
        pygame.display.update()

3.可自由移动矩形

vel_y=1
myfont=pygame.font.Font(None,60)
textImage=myfont.render("Hello Pygame",True,white)
while True:
    for event in pygame.event.get():
        if event.type in (QUIT,KEYDOWN):
            sys.exit()
        screen.fill((0,0,200))

        # #draw a circle
        # color =255,255,0
        # posotion=300,250
        # radius=100
        # width=10
        # pygame.draw.circle(screen,color,posotion,radius,width)
        # pygame.display.update()

        #move a rectangles
        pos_x+=vel_x
        pos_y+=vel_y

        #keep rectangle on the screen
        if pos_x>500 or pos_x<0:
            vel_x=-vel_x
        if pos_y>500 or pos_y<0:
            vel_y=-vel_y

        #draw the rectangle
        color=255,255,0
        width=0 #solid fill
        pos=pos_x,pos_y,100,100
        pygame.draw.rect(screen,color,pos,width)
        pygame.display.update()

4.绘制弧形

        # width=10
        # pygame.draw.circle(screen,color,posotion,radius,width)
        # pygame.display.update()

        # #move a rectangles
        # pos_x+=vel_x
        # pos_y+=vel_y

        # #keep rectangle on the screen
