基于Python制作三款起床闹钟的示例代码

下面我将详细讲解“基于Python制作三款起床闹钟的示例代码”的完整攻略。

简介

起床是每天必须要做的事情，但很多人都有困难。为了帮助你更容易地起床，我们提供了三个 Python 闹钟项目。这些闹钟可以让你自由选择你最喜欢的方式去唤醒你的晨感。

安装

使用这些 Python 闹钟项目，需要先安装 Python。请参阅Python网站获取有关如何在特定操作系统上安装 Python 的详细信息。Python版本应大于等于3.5。

安装 Python 后，我们需要安装两个必要的 Python 包：pygame 和 playsound。使用以下命令在终端中安装它们。

pip install pygame
pip install playsound

项目一：数字闹钟

数字闹钟是我们第一个 Python 闹钟项目。它使用 Python 的 datetime 模块获取当前时间和设置闹钟时间。根据条件不断判断当前时间是否与闹钟时间一致，若一致则使用 tkinter 呈现消息框提醒你，直到你关闭消息框为止。下面是示例代码：

import tkinter
import datetime
import time

def set_alarm(alarm_time):
     alarm_hour = alarm_time[0]
     alarm_minute = alarm_time[1]
     while True:
          now = datetime.datetime.now()
          current_hour = now.hour
          current_minute = now.minute
          if (alarm_hour == current_hour and alarm_minute == current_minute):
              print("Time to Wake up")
              break

def get_alarm_time():
     alarm_input = input("Set the alarm time : [HH:MM] ")
     try:
          alarm_time = [int(n) for n in alarm_input.split(":")]
          display_alarm_time = datetime.datetime.now().replace(hour=alarm_time[0],minute=alarm_time[1],second=0)
          print("Alarm Set For :{}".format(display_alarm_time.strftime("%I:%M:%S %p")))
          return alarm_time
     except ValueError:
          print("Invalid Time Entered")
          return get_alarm_time()

alarm_time = get_alarm_time()
set_alarm(alarm_time)

项目二：游戏闹钟

游戏闹钟是我们第二个 Python 闹钟项目。它使用 pygame 模块生成一个易于播放的声音，并在触发闹钟时播放一个简单的游戏。你可以选择 Pygame 默认的 .wav 音频文件或者自己用音频剪辑软件制作自己的音频文件。下面是示例代码：

import pygame
import datetime
import time

pygame.init()

display_width = 800
display_height = 700

gameDisplay = pygame.display.set_mode((display_width,display_height))
pygame.display.set_caption('Game Alarm Clock')
clock = pygame.time.Clock()

crash_sound = pygame.mixer.Sound("examples/alarm-clock/alarm_sound.wav")

def blit_text(surface, text, pos, font, color=pygame.Color('black')):
    words = [word.split(' ') for word in text.splitlines()]  # 2D array where each row is a list of words.
    space = font.size(' ')[0]  # The width of a space.
    max_width, max_height = surface.get_size()
    x, y = pos
    for line in words:
        for word in line:
            word_surface = font.render(word, 0, color)
            word_width, word_height = word_surface.get_size()
            if x + word_width >= max_width:
                x = pos[0]  # Reset the x.
                y += word_height  # Start on new row.
            surface.blit(word_surface, (x, y))
            x += word_width + space
        x = pos[0]  # Reset the x.
        y += word_height  # Start on new row.

def message_display(text):
    largeText = pygame.font.Font('freesansbold.ttf',20)
    TextSurf, TextRect = text_objects(text, largeText)
    TextRect.center = ((display_width/2),(display_height/2))
    gameDisplay.blit(TextSurf, TextRect)
    crash_sound.play()
    pygame.display.update()
    time.sleep(2)

def text_objects(text, font):
    textSurface = font.render(text, True, pygame.Color('black'))
    return textSurface, textSurface.get_rect()

def game_loop():
    is_game_over = False
    while not is_game_over:
        for event in pygame.event.get():
            if event.type == pygame.QUIT:
                is_game_over = True

        gameDisplay.fill(pygame.Color('white'))
        pygame.display.update()
        clock.tick(60)

def set_alarm(game_time):
     alarm_hour = game_time[0]
     alarm_minute = game_time[1]
     while True:
          now = datetime.datetime.now()
          current_hour = now.hour
          current_minute = now.minute
          if (alarm_hour == current_hour and alarm_minute == current_minute):
              message_display("Time to Wake up")
              game_loop()
              break

def get_game_time():
     alarm_input = input("Set the wakeup game time [HH:MM] :")
     try:
          alarm_time = [int(n) for n in alarm_input.split(":")]
          display_alarm_time = datetime.datetime.now().replace(hour=alarm_time[0],minute=alarm_time[1],second=0)
          print("Alarm is set to :{}".format(display_alarm_time.strftime("%I:%M:%S %p")))
          return alarm_time
     except ValueError:
          print("Invalid time entered")
          return get_game_time()

game_time = get_game_time()
set_alarm(game_time)

项目三：动画闹钟

动画闹钟是我们最后一个 Python 闹钟项目。它使用 PyQt5 创建了一个图形用户界面(GUI)，在触发闹钟时会显示动画效果。这个过程需要有效益的计算机图形库 PyQt5 和样式表QSS。下面是示例代码：

import sys
from PyQt5.QtCore import *
from PyQt5.QtGui import *
from PyQt5.QtWidgets import *

class Example(QWidget):

    def __init__(self):
        super().__init__()

        self.initUI()

    def initUI(self):
        self.setGeometry(300, 300, 470, 430)
        self.setWindowTitle('Animation Alarm')
        self.label = QLabel(self)
        pixmap = QPixmap('animation.gif')
        self.label.setPixmap(pixmap)
        self.label.setGeometry(0,-100,480,480)

        self.timeEdit = QTimeEdit(self)
        self.timeEdit.move(45,360)

        btn1 = QPushButton("Set Alarm",self)
        btn1.move(300,360)
        btn1.clicked.connect(self.startTimer)

        self.show()

    def paintEvent(self, event):
        qp = QPainter()
        qp.begin(self)
        self.drawRectangles(qp)
        qp.end()

    def drawRectangles(self, qp):
        color = QColor(0, 0, 0)
        color.setNamedColor('#d4d4d4')
        qp.setPen(QPen(Qt.red, 4, Qt.SolidLine))
        qp.setBrush(QBrush(Qt.SolidPattern))
        qp.drawRect(20, 80, 400, 240)

    def startTimer(self):
        self.timer = QTimer(self)
        self.timer.timeout.connect(self.countdown)
        self.timer.start(1000)

    def countdown(self):
        timer_value = self.timeEdit.time().toString()
        current_time = QDateTime.currentDateTime().toString()
        if timer_value == current_time[11:16]:
            QMessageBox.information(self,"Alert", "Time is up! Timer finished!")
            self.timer.stop()
            self.label.move(0,0)
        else:
            print("Still waiting...")

if __name__ == '__main__':
    app = QApplication(sys.argv)
    ex = Example()
    sys.exit(app.exec_())

以上就是三个 Python 闹钟项目的示例代码、操作文档及开发环境的详细攻略。希望对你的 Python 学习之旅有所帮助。
