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：

复制代码
import datetime
import pygame
import os
import time
import random
from pynput.keyboard import Key,Listener
复制代码
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。

复制代码
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(
"\", "/")
复制代码
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）。

复制代码
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", ""))
复制代码
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。

复制代码
finding = open("dates_one.txt", "a")
finding.close()
finding = open("dates_one.txt", "r")
dates_undone_one = finding.readlines()
finding.close()

//代码效果参考：https://v.youku.com/v_show/id_XNjQwMDM5NTU2NA==.html
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", ""))
复制代码
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。

复制代码
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", "")
复制代码
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）。

复制代码
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:

//代码效果参考：https://v.youku.com/v_show/id_XNjQwNjg0ODkyMA==.html
while finder[-1] == "\n":
finder = finder[:-1]
except:
while False:
print()
with open("songs_two.txt", "w") as finding:
finding.write(finder)
复制代码
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。

复制代码

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:
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:

print()
songs = {}
