Python使用Pygame绘制时钟

本文实例为大家分享了Python使用Pygame绘制时钟的具体代码，供大家参考，具体内容如下

前提条件：

需要安装pygame

功能：

1.初始化界面显示一个时钟界面

2.根据当前的时间实现时针、分针、秒针的移动

import pygame, sys, random, math
from datetime import datetime
from pygame.locals import *

def print_text(font, x, y, text, color=(255, 255, 255)):
  img_text = font.render(text, True, color)
  screen.blit(img_text, (x, y))

pygame.init()

# 屏幕大小
screen = pygame.display.set_mode((600, 500))
# 标题
pygame.display.set_caption("时钟")
# 字体
font1 = pygame.font.Font(None, 24)
# 圆心位置
pos_x = 300
pos_y = 250
# 圆的半径
radius = 250
r = random.randint(0, 255)
g = random.randint(0, 255)
b = random.randint(0, 255)

while True:
  for event in pygame.event.get():
    if event.type == QUIT:
      sys.exit()
  keys = pygame.key.get_pressed()
  if keys[K_ESCAPE]:
    sys.exit()
  screen.fill((0, 0, 100))
  color = r, g, b
  pygame.draw.circle(screen, color, (pos_x, pos_y), radius, 6)
  # 绘制数字1-12
  for i in range(1, 13):
    angle = math.radians((360 / 12) * i - 90)
    x = math.cos(angle) * (radius - 20) - 10
    y = math.sin(angle) * (radius - 20) - 10
    print_text(font1, pos_x + x, pos_y + y, str(i))
  # 绘制时针
  hour = datetime.today().hour % 12 # 获取当前时间的小时
  hour_angle = math.radians((360 / 12) * hour - 90)
  hour_x = math.cos(hour_angle) * (radius - 90)
  hour_y = math.sin(hour_angle) * (radius - 90)
  pygame.draw.line(screen, (255, 0, 0), (pos_x, pos_y), (pos_x + hour_x, pos_y + hour_y), 12)
  # 绘制分针
  minutes = datetime.today().minute # 获取当前时间的分钟
  minutes_angle = math.radians((360 / 60) * minutes - 90)
  minutes_x = math.cos(minutes_angle) * (radius - 70)
  minutes_y = math.sin(minutes_angle) * (radius - 70)
  pygame.draw.line(screen, (0, 255, 0), (pos_x, pos_y), (pos_x + minutes_x, pos_y + minutes_y), 8)
  # 绘制秒针
  seconds = datetime.today().second # 获取当前时间的秒数
  seconds_angle = math.radians((360 / 60) * seconds - 90)
  seconds_x = math.cos(seconds_angle) * (radius - 30)
  seconds_y = math.sin(seconds_angle) * (radius - 30)
  pygame.draw.line(screen, (0, 0, 255), (pos_x, pos_y), (pos_x + seconds_x, + pos_y + seconds_y), 4)
  # 覆盖圆心
  pygame.draw.circle(screen, (255, 255, 255), (pos_x, pos_y), 10)

  pygame.display.update()

运行结果：
