如何根据实时在声音播放列表序列中注入声音时间项？

Question

我觉得这有点复杂，但让我们开始吧！

输入：

1. schedule_items：字典列表，每本字典都有这个键：

• title：标题将是一个字符串
• duration_milliseconds：duration_milliseconds 将是每个音轨的持续时间，以毫秒为单位
• start_datetime：start_datetime 将是一个 datetime.datetime，它将显示音轨开始的具体时间。序列列表项将具有 start_datetime_i+1 = start_datetime_i+duration_milliseconds_i

2. time_collection：包含标准两项的列表。

第一个是带键的字典：

• collection_title：collection_title将是time_collection的标题：
• collection_case：collection_case 将是 1 和 4 之间的数字（1 案例：01:00|13:00,02:00|14:00,03:00|15:00， ...12:00|24:00（12 项）2 案例：01:00,02:00,...,12:00,13:00,...24:00（24 项） 3 案例：01:00|13:00,01:30|13:30,02:00|14:00,02:30|14:30,03:00|15:00,...12 :00|24:00,12:30|24:30（24 项）和 4 案例：01:00,01:30,02:00,02:30,03:00,...12: 00,12:30,..24:00,24:30（48 项））。
• append_duration_milliseconds：append_duration_milliseconds 将是连接 time_collection 的音轨的持续时间。例如，如果广播制作人希望每次播放 Time 时都会在其余音乐节目继续之前播放音轨，那么 append_duration_millisecond 将显示这个额外时间。

time_collection 列表的第二个项目将是一个列表，其中项目总数 = 所选 collection_case 的项目（case=1 12 项，case=2 24 项，case=3 24 项，case=4 48 项）。

每一项都将是一本带键的字典：

• title：标题将是一个文本，例如：“时间是 1 点。”
• duration_milliseconds：duration_milliseconds 将是表示时间的音轨的持续时间（例如一点钟 10*1000）
• when_to_play：when_to_play会根据集合大小写为“01:00|13:00”或“01:00”或“01:30|13:30”或“24:30”等字符串。

输出：

标题为schedule_items_final的列表：其中将包含输入的所有schedule_items，根据开始日期时间输入的适当time_collection项目。

如果 schedule_items 的 duration 和 start_datetime 大于 1 小时（或 30 分钟），则音轨将被裁剪成多个部分（可能超过两个）并且这些部分的标题可能会说明这是一个部分。例如，如果我将标题为“bla bla bla”的 schedule_item 裁剪为三部分，则裁剪后的项目将具有标题“bla bla bla part 1”、“bla bla bla part 2”、“bla bla bla part 3”。

我相信问题已经得到很好的解释，但如果您对问题的任何部分感到困惑，请随时发表评论。

• 我过去制作这个程序非常成功（但我已经失去了它），所以我很确定我们可以重新制作它（也许更好更快）。

一个小例子：

输入：

schedule_items=[{"title":"1","duration_milliseconds"1000*60*60*1.5,"start_datetime":datetime.now()},{"title":"2","duration_milliseconds":1000*60*10*2,"start_datetime":datetime.now()+timedelta(seconds=60*60*1.5)},{"title":"3","duration_milliseconds":1000*60*2,"start_datetime":datetime.now()+timedelta(seconds=60*60*1.5+60*10*2)},{"title":"4","duration_milliseconds":1000*60*60*2,"start_datetime":datetime.now()+timedelta(seconds=60*60*1.5+60*10*2+60*2)}]
time_collection=[{"collection_title":"Time collection 1","collection_case":1,"append_duration_milliseconds":1000*25},[{"title":"The time is 1","duration_milliseconds":1000*5,"when_to_play":"01:00|13:00"},{"title":"The time is 2","duration_milliseconds":1000*5,"when_to_play":"02:00|14:00"},{"title":"The time is 3","duration_milliseconds":1000*5,"when_to_play":"03:00|15:00"},{"title":"The time is 4","duration_milliseconds":1000*5,"when_to_play":"04:00|16:00"},{"title":"The time is 5","duration_milliseconds":1000*5,"when_to_play":"05:00|17:00"},{"title":"The time is 6","duration_milliseconds":1000*5,"when_to_play":"06:00|18:00"},{"title":"The time is 7","duration_milliseconds":1000*5,"when_to_play":"07:00|19:00"},{"title":"The time is 8","duration_milliseconds":1000*5,"when_to_play":"08:00|20:00"},{"title":"The time is 9","duration_milliseconds":1000*5,"when_to_play":"09:00|21:00"},{"title":"The time is 10","duration_milliseconds":1000*5,"when_to_play":"10:00|22:00"},{"title":"The time is 11","duration_milliseconds":1000*5,"when_to_play":"11:00|23:00"},{"title":"The time is 12","duration_milliseconds":1000*5,"when_to_play":"12:00|24:00"}]]

如果 datetime.now = 22/04/2023 23:58:00 那么预期输出将是：

一个。第一项：

{"title":"1 part 1","duration_milliseconds":1000*60*2,"start_datetime":22/04/2023 23:58:00}

b。第二项：

{"title":"The time is 12","duration_milliseconds":1000*30,"start_datetime":23/04/2023 00:00:00,"when_to_play":"12:00|24:00"}

c。第三项：

{"title":"1 part 2","duration_milliseconds"1000*59.5,"start_datetime":23/04/2023 00:00:30}

d。第四项：

{"title":"The time is 1","duration_milliseconds"1000*30,"start_datetime":23/04/2023 01:00:00,"when_to_play":"01:00|13:00"}

e。第五项：

{"title":"1 part 3","duration_milliseconds":1000*28.5,"start_datetime":23/04/2023 01:00:30}

f.项目编号 6：

{"title":"2","duration_milliseconds":1000*60*10*2,"start_datetime":23/04/2023 01:29:00}

克。商品编号 7：

{"title":"3","duration_milliseconds":1000*60*2,"start_datetime":23/04/2023 01:49:00}

h。项目编号 8：

{"title":"4 part 1","duration_milliseconds":1000*60*9,"start_datetime":23/04/2023 01:51:00}

我。项目编号 9：

{"title":"The time is 2","duration_milliseconds"1000*30,"start_datetime":23/04/2023 02:00:00,"when_to_play":"02:00|14:00"}

j。项目编号 10：

{"title":"4 part 2","duration_milliseconds":1000*59.5,"start_datetime":23/04/2023 02:00:30}

k。商品编号 11：

{"title":"The time is 3","duration_milliseconds"1000*30,"start_datetime":23/04/2023 03:00:00,"when_to_play":"03:00|15:00"}

l。项目编号 12：

{"title":"4 part 3","duration_milliseconds":1000*56.5,"start_datetime":23/04/2023 03:00:30}

在此示例中，程序从 22/04/2023 23:58:00 开始到 23/04/2023 03:57:00 结束。
