本文给大家汇总介绍了下使用Python实现模拟时钟的代码,一共3个例子,后两个是基于QT实现,有需要的小伙伴可以参考下

# coding=utf8 import sys, pygame, math, random from pygame.locals import * from datetime import datetime, date, time def print_text(font, x, y, text, color=(255,255,255)): imgtext = font.render(text, True, color) screen.blit(imgtext, (x,y)) def wrap_angle(angle): return abs(angle%360) # main pygame.init() screen = pygame.display.set_mode((600,500)) pygame.display.set_caption("CLOCK") font = pygame.font.Font(None, 36) orange = 220,180,0 white = 255,255,255 yellow = 255,255,0 pink = 255,100,100 pos_x = 300 pos_y = 250 radius = 250 angle = 360 # repeating loop 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)) # draw circle pygame.draw.circle(screen, white, (pos_x,pos_y), radius, 6) # draw the clock number 1-12 for n in range(1,13): angle = math.radians(n*(360/12)-90) x = math.cos(angle)*(radius-20)-10 y = math.sin(angle)*(radius-20)-10 print_text(font, pos_x+x, pos_y+y, str(n)) # get the time of day today = datetime.today() hours = today.hour%12 minutes = today.minute seconds = today.second # draw the hours hand hour_angle = wrap_angle(hours*(360/12)-90) hour_angle = math.radians(hour_angle) hour_x = math.cos(hour_angle)*(radius-80) hour_y = math.sin(hour_angle)*(radius-80) target = (pos_x+hour_x, pos_y+hour_y) pygame.draw.line(screen, pink, (pos_x,pos_y), target, 12) # draw the minutes hand min_angle = wrap_angle(minutes*(360/60)-90) min_angle = math.radians(min_angle) min_x = math.cos(min_angle)*(radius-60) min_y = math.sin(min_angle)*(radius-60) target = (pos_x+min_x, pos_y+min_y) pygame.draw.line(screen, orange, (pos_x,pos_y), target, 12) # draw the seconds hand sec_angle = wrap_angle(seconds*(360/60)-90) sec_angle = math.radians(sec_angle) sec_x = math.cos(sec_angle)*(radius-40) sec_y = math.sin(sec_angle)*(radius-40) target = (pos_x+sec_x, pos_y+sec_y) pygame.draw.line(screen, yellow, (pos_x,pos_y), target, 12) # draw the center pygame.draw.circle(screen, white, (pos_x,pos_y), 20) print_text(font, 0, 0, str(hours) + ":" + str(minutes) + ":" + str(seconds)) pygame.display.update()
再来一个例子

例三:
主要是模仿了qt自带的clock例子,然后 通过 python的语法 进行实现,
同时添加了秒针 的实现
用到的工具 有qt 4.8;python 2.7 ;pyqt
import sys from PyQt4.QtCore import * from PyQt4.QtGui import * class clock (QWidget): def __init__(self): QWidget.__init__(self,windowTitle="python clock") timer = QTimer(self) self.connect(timer, SIGNAL("timeout()"),self,SLOT("update()")) timer.start(1000) self.resize(200,200) def paintEvent(self,e): hourColorHand = QPolygon([QPoint(7,8),QPoint(-7,8),QPoint(0,-30)]) minuteColorHand = QPolygon([QPoint(7,8),QPoint(-7,8),QPoint(0,-70)]) secondColorHand = QPolygon([QPoint(3,8),QPoint(-3,8),QPoint(0,-90)]) hourColor = QColor(127,0,127) minuteColor = QColor(0,127,127,191) secondColor = QColor(0,100,100,100) painter = QPainter(self); side = min(self.width(),self.height()) atime =QTime.currentTime() painter.setRenderHint(QPainter.Antialiasing) painter.translate(self.width()/2,self.height()/2) painter.scale(side/200,side/200) painter.setPen(Qt.NoPen) painter.setBrush(hourColor) painter.save() painter.rotate(30.0*(atime.hour() + atime.minute()/60.0)) painter.drawConvexPolygon(hourColorHand) painter.restore() painter.setPen(hourColor) for i in range(0,12): painter.drawLine(88,0,96,0) painter.rotate(30.0) painter.setPen(Qt.NoPen) painter.setBrush(minuteColor) painter.save() painter.rotate(6.0*(atime.minute()+atime.second()/60.0)) painter.drawConvexPolygon(minuteColorHand) painter.restore() painter.setPen(minuteColor) for i in range(0,60) : if (i%5)!=0 : painter.drawLine(92,0,96,0) painter.rotate(6.0) painter.setPen(Qt.NoPen) painter.setBrush(secondColor) painter.save() painter.rotate(6.0 * atime.second()) painter.drawConvexPolygon(secondColorHand) painter.restore() if __name__ == "__main__" : q = QApplication(sys.argv) s = clock() s.show() q.exec_()
