Python：一个闹钟

随着一个《霍格沃茨：一段校史》风格的大字（呃，这字好像并不大……）标题的出现，无聊的我没事干，又开始整活了~

之前我做的程序，一个使用了Tkinter库，一个则是Pygame，总之都是带有图形化的界面的。但作为一个懒汉，我自然能懒必懒（这点我非常有自知之明），这次，我就来一个简单朴素的没有图形界面的程序。

这是一个闹钟，一个可以设定时间的闹钟（虽然操作的界面有点简陋，但丝毫不影响它的强大功能）。

首先，我们要编闹钟的响铃程序。

我们先新建一个文件，后缀是“.pyw”（这样可以保证程序运行的时候不会弹出一个Python自带的窗口）。

首先，老规矩，第一行一定是：

#coding:utf-8

然后，我们要导入所需的模块：

import datetime
import pygame
import os
import time
import random
from pynput.keyboard import Key,Listener

本次所需的模块不多，由于都是我原先安装好的，所以我也并不确定它们是否要用pip安装。当然，使用PyCharm进行编程可以自动为你安装你使用到的未安装的模块。

all_songs=[]
all_songs_dict={}
for root, dirs, names in os.walk("d:/Users/{}/Music".format(os.getlogin())):
    for filename in names:
        if os.path.join(root, filename)[-4:] == ".mp3" or os.path.join(root, filename)[-4:] == ".ogg":
            all_songs.append(os.path.join(root, filename)[os.path.join(root, filename).find("\\") + 1:-4])
            all_songs_dict[
                os.path.join(root, filename)[os.path.join(root, filename).find("\\") + 1:-4]] = os.path.join(root,
                                                                                                             filename).replace(
                "\\", "/")

首先，我们需要获取电脑中的音乐。我们用os.walk获取Music文件夹中的所有ogg和mp3文件（这是由于我播放音乐使用的是Pygame，它似乎只支持这两种文件的音乐）。同时，通过对路径字符串的文字处理，提取出音乐名称存储入列表all_songs，并将其和原先的路径对应存入字典all_songs_dict。这时存入这两个变量中的音乐信息相当于一种保险机制，可以确保在找不到铃声文件时有备用铃声可以使用（当然，如果你的音乐文件夹是空的，这当然没用；但我不认为你的文件夹中会没有音乐）。

finding = open("alarm_list.txt", "a")
finding.close()
finding = open("alarm_list.txt", "r")
alarm_list_undone = finding.readlines()
finding.close()
alarm_list = []
for i in alarm_list_undone:
    alarm_list.append(i.replace("\n", ""))

我们的闹钟时间当然需要存储在某个文件中，这样才能防止这个信息丢失。于是，我们打开了一个“alarm_list.txt”文件（为防止文件不存在，我们需要先用写入的模式打开一次文件，这样可以在文件不存在时创建；同时为防止这个操作清空文件，我们必须用追加写的“a”而不是“w”）。我们会读取文件中的内容，并删除换行后存入alarm_list。我们不必忧心文件中有无法识别的内容，因为文件是通过另一个编辑程序写入的，那个程序会保证文件内容是这个程序所能识别的。

finding = open("dates_one.txt", "a")
finding.close()
finding = open("dates_one.txt", "r")
dates_undone_one = finding.readlines()
finding.close()
finding = open("dates_two.txt", "a")
finding.close()
finding = open("dates_two.txt", "r")
dates_undone_two = finding.readlines()
finding.close()
dates = {}
for i in range(len(dates_undone_one)):
    dates[dates_undone_one[i].replace("\n", "")] =eval( dates_undone_two[i].replace("\n", ""))

同理，对“dates_one.txt”和“dates_two.txt”也需要类似的处理。当然，因为文件中存储有表格，我们有必要用eval()函数回复它的表格类型。第二个不同在于这两个文件的内容会被存入一个字典，而不是表格。

finding = open("songs_one.txt", "a")
finding.close()
finding = open("songs_one.txt", "r")
songs_undone_one = finding.readlines()
finding.close()
finding = open("songs_two.txt", "a")
finding.close()
finding = open("songs_two.txt", "r")
songs_undone_two = finding.readlines()
finding.close()
songs = {}
for i in range(len(songs_undone_two)):
    try:
        open(songs_undone_two[i].replace("\n", ""),"r")
    except:
        songs_undone_two[i]=all_songs_dict[all_songs[random.randint(0,len(all_songs)-1)]]+"\n"
        with open("songs_two.txt", "w")as finding:
            finding.writelines(songs_undone_two)
for i in range(len(songs_undone_one)):
   songs[songs_undone_one[i].replace("\n", "")] = songs_undone_two[i].replace("\n", "")

在对“songs_one.txt”和“songs_two.txt”的处理中，我们就需要用到表格all_songs了。为保证音乐都存在，它会尝试打开路径所指向的文件。如果找不到文件，它会将音乐修改为all_songs中所记录的随机一个音乐（在这里可以进行改善：加一个if判断，如果路径指向的文件后缀不是“.mp3”或“.ogg”，则也要修改音乐。这个工作感兴趣的读者可以自行加上，在此我不再给出代码——这主要是由于我在解释我的程序代码时即使发现了不合理之处，只要不是大问题，就也不愿再行修改的习惯）。

finding = open("alarm_list.txt", "r")
finder=finding.read()
try:
    while finder[-1] == "\n":
        finder = finder[:-1]
except:
    while False:
        print()
with open("alarm_list.txt", "w") as finding:
    finding.write(finder)
finding = open("dates_one.txt", "r")
finder=finding.read()
try:
    while finder[-1] == "\n":
        finder = finder[:-1]
except:
    while False:
        print()
with open("dates_one.txt", "w") as finding:
    finding.write(finder)
finding = open("dates_two.txt", "r")
finder=finding.read()
try:
    while finder[-1] == "\n":
        finder = finder[:-1]
except:
    while False:
        print()
with open("dates_two.txt", "w") as finding:
    finding.write(finder)

finding = open("songs_one.txt", "r")
finder=finding.read()
try:
    while finder[-1] == "\n":
        finder = finder[:-1]
except:
    while False:
        print()
with open("songs_one.txt", "w") as finding:
    finding.write(finder)
finding = open("songs_two.txt", "r")
finder=finding.read()
try:
    while finder[-1] == "\n":
        finder = finder[:-1]
except:
    while False:
        print()
with open("songs_two.txt", "w") as finding:
    finding.write(finder)

我的删除闹钟的程序片段不知为何，一直有一些BUG，会在删除处于结尾的闹钟时留下空行（这会导致程序运行出错）。于是，我们很有必要对其的后果作出一些挽回：将每一个文件结尾的换行符删除。而这个程序就是进行了这样一个工作。

def delete(i):
    global all_songs, all_songs_dict, alarm_list, dates, songs,alarm_list_undone,dates_undone_one,dates_undone_two,songs_undone_one,songs_undone_two
    try:
        try:
            alarm_list_undone.remove(i)
            alarm_list[-1] = alarm_list[-1].replace("\n", "")
        except:
            alarm_list_undone.remove(i + "\n")
    except:
        if False:
            print()
    alarm_list.remove(i)
    with open("alarm_list.txt", "w") as finding:
        finding.writelines(alarm_list_undone)
    for j in range(len(songs_undone_one)):
        if songs_undone_one[j] == i or songs_undone_one[j] == i + "\n":
            songs_undone_one.pop(j)
            songs_undone_two.pop(j)
            try:
                songs_undone_one[-1]=songs_undone_one[-1].replace("\n", "")
                songs_undone_two[-1]=songs_undone_two[-1].replace("\n", "")
            except:
                if False:
                    print()
    songs = {}
    for j in range(len(songs_undone_one)):
        songs[songs_undone_one[j].replace("\n", "")] = songs_undone_two[j].replace("\n", "")
    with open("songs_one.txt", "w") as finding:
        finding.writelines(songs_undone_one)
    with open("songs_two.txt", "w") as finding:
        finding.writelines(songs_undone_two)
    for j in range(len(dates_undone_one)):
        if dates_undone_one[j] == i or dates_undone_one[j] == i + "\n":
            dates_undone_one.pop(j)
            dates_undone_two.pop(j)
            try:
                dates_undone_one[-1]=dates_undone_one[-1].replace("\n", "")
                dates_undone_two[-1]=dates_undone_two[-1].replace("\n", "")
            except:
                if False:
                    print()
    dates = {}
    for j in range(len(dates_undone_one)):
        dates[dates_undone_one[j].replace("\n", "")] = dates_undone_two[j].replace("\n", "")
    with open("dates_one.txt", "w") as finding:
        finding.writelines(dates_undone_one)
    with open("dates_two.txt", "w") as finding:
        finding.writelines(dates_undone_two)

这就是刚刚提到的有BUG的删除程序。这里输入的i是闹钟的时间（在这个程序中，闹钟时间具有唯一性，一个时间只对应一个闹钟）。这个程序试图删除i所对应的所有信息，但是，对于位于文件和表格结尾的闹钟，它不能有效处理。我试图使它删除上一条末尾的换行符，但显然出现了某种错误。我因此不得不另加一行代码来弥补它的后果。

def play_it(url):
    global Listener
    pygame.mixer.init()
    t = pygame.mixer.music.load(url)
    pygame.mixer.music.play()

    def on_release(key):
        if key == Key.space:
            pygame.mixer.music.stop()

    with Listener(on_release=on_release) as Listener:
        Listener.join()

播放程序，用于在时间到时播放音乐。这里不仅使用了Pygame的音乐播放，还使用了Pynput的键盘监听，这样可以在按下空格时关闭音乐（当然，有时候在打字时也许会误关闹钟，但这无关紧要——你完全可以设置另一个不常用的键来关闭闹钟）。

def alarm():
    global all_songs,all_songs_dict,alarm_list,dates,songs
    while True:
        try:

毫无疑问，在这些代码后面，跟的是程序的核心代码。但接下来这一段无疑令人失望：

            e = time.time()
            finding = open("alarm_list.txt", "a")

                    open(songs_undone_two[i].replace("\n", ""), "r")
                except:

            finding = open("songs_one.txt", "r")

            with open("songs_two.txt", "w") as finding:
                finding.write(finder)

没错，这就是前面的存储载入的代码。这是为了刷新对文件的读取，毕竟，你很有可能会在程序运行时修改闹钟。

            for i in alarm_list:
                if str(datetime.datetime.now())[11:16] == i:
                    if time.strftime("%w", time.localtime()) in dates.get(i):
                        url = songs.get(i)
                        True_False=int(time.strftime("%Y", time.localtime())) < int(dates.get(i)[-1][4:8]) or (int(time.strftime("%Y", time.localtime())) == int(dates.get(i)[-1][4:8]) and int(time.strftime("%j", time.localtime())) <= int(dates.get(i)[-1][9:]))
                        if int(time.strftime("%Y", time.localtime())) > int(dates.get(i)[-1][4:8]) or (
                                int(time.strftime("%Y", time.localtime())) == int(dates.get(i)[-1][4:8]) and int(
                                time.strftime("%j", time.localtime())) >= int(dates.get(i)[-1][9:])):
                            delete(i)
                        if True_False:
                            play_it(url)
                else:
                    if int(time.strftime("%Y", time.localtime())) > int(dates.get(i)[-1][4:8]) or (
                            int(time.strftime("%Y", time.localtime())) == int(dates.get(i)[-1][4:8]) and int(
                        time.strftime("%j", time.localtime())) > int(dates.get(i)[-1][9:])):
                        delete(i)
                    if int(time.strftime("%Y", time.localtime())) == int(dates.get(i)[-1][4:8]) and int(time.strftime("%j", time.localtime())) == int(dates.get(i)[-1][9:]) and int(str(datetime.datetime.now())[11:13])*60+int(str(datetime.datetime.now())[14:16]) > int(i[:2])*60+int(i[3:]):
                        delete(i)

这才是你们期待的核心代码（虽然功能很核心，但却还是很简单的）我们将闹钟列表遍历，将时间与闹钟所设置的时间所比对，如果现在是某个闹钟所设定的时间，同时现在日期在一星期中的位置（暂且就这么表述，我突然发现像“星期一”之类的词似乎……没有一个统称）也存在于对应的表格中，同时现在的日期也没有超过闹钟的截止日期，我们就会响铃（铃声会遵从该闹钟的设置）。同时，对于已截至的闹钟，它会予以删除。

这样，响铃的程序就已初步完成。但是，为了使程序不挤占进程（很多闹钟程序都会如此），我们还是有必要加上这一段代码：

            time.sleep(1 - (time.time() - e))
        except:
            time.sleep(1 - (time.time() - e))

当然最后得运行函数：

alarm()

这样，我们就把闹钟的程序完成了。

你是否疑惑：我们如何设置闹钟？这后面的内容，我们就来解决这一件事。

最简单的办法，当然是将闹钟手动输入到文件中。“alarm_list.txt”中需要输入的是闹钟的时间，格式“00:00”；“dates_one.txt”和“songs_one.txt”中储存的其实也是这一内容。“songs_two.txt”中是音乐的路径，这个也没问题；最重要的是“dates_two.txt”。我们不妨举个例子。“['1', '2', '3', '4', '5', 'kill9999&99']”，这是什么意思？“1”“2”“3”“4”“5”指响铃的星期，其中“0”代表周日，“1”代表周一，后面以此类推。“kill9999&99”是闹钟截至日期，或者说有效期，“9999”是年，“99”是在这年中的天数，“kill9999&99”意为“有效期至公元9999年的4月9日”，在这里我们可以简单粗暴的认为是永不停止（因为一般来说，这个程序是绝对不会运行到那一天的）。也就是说“['1', '2', '3', '4', '5', 'kill9999&99']”的意思大概就是，每周工作日响铃，永远有效。

当然，这么做实际会比较繁琐，因此我经过一连串更繁琐的步骤后，制作了一个闹钟的设置程序（在此只给出代码，因为它里面主要都是些简单却反复的内容）：

这个程序不能是pyw文件，而必须是py（因为它需要输入与输出）。我们需要将其和刚刚的响铃程序放在同一个文件夹中，并对两个程序分别创建一个快捷方式。然后，我们要将响铃程序放入“启动”文件夹（在C盘，名称叫“StartUp”。它在我的电脑上路径为“C:\ProgramData\Microsoft\Windows\Start Menu\Programs\StartUp”，不同电脑上路径可能稍有不同，但搜索总是能找到的）。而另一个，这个设置程序的快捷方式，你可以放在桌面，方便打开程序。
