获取日期范围内的数据

Question

[
  {
    start_time: "09:00",
    end_date: "2015-12-20",
    end_time: "13:55",
    start_date: "2015-12-15"
  },
  {
    start_time: "06:07",
    end_date: "2015-12-24",
    end_time: "08:09",
    start_date: "2015-12-22"
  },
  {
    start_time: "09:30",
    end_date: "2015-12-01",
    end_time: "18:00",
    start_date: "2015-12-01"
  },
  {
    start_time: "01:00",
    end_date: null,
    end_time: "04:00",
    start_date: null,

  },
  {
    start_time: "05:00",
    end_date: null,
    end_time: "08:00",
    start_date: null,

  }
]

我有上面的数据。 我将传递开始日期和结束日期，它必须产生日期之间的数据，如果日期不存在，则必须插入空数据（开始日期和结束日期为null的字典）。 下面列出了日期范围为“ 2015-12-02”，“ 2015-12-16”之间的示例。 结果必须如下所示。

[
  {
    start_time: "01:00",
    end_date: null,
    end_time: "04:00",
    start_date: null,

  },
  {
    start_time: "05:00",
    end_date: null,
    end_time: "08:00",
    start_date: null,

  },

  {
    start_time: "09:00",
    end_date: "2015-12-20",
    end_time: "13:55",
    start_date: "2015-12-15"
  },
  {
    start_time: "01:00",
    end_date: null,
    end_time: "04:00",
    start_date: null,

  },
  {
    start_time: "05:00",
    end_date: null,
    end_time: "08:00",
    start_date: null,

  },
  {
    start_time: "06:07",
    end_date: "2015-12-24",
    end_time: "08:09",
    start_date: "2015-12-22"
  }
]

有人可以帮我吗？

Answer 1

基本上，您应该能够在字符串之间进行比较（比较功能是日期比较）。 所以我首先将其转换为日期-

import time
start = "2015-12-02"
start_date = time.strptime(start, "%Y-%m-%d")
end = "2015-12-02"
end_date = time.strptime(end, "%Y-%m-%d")

现在，您可以> <=运算符并遍历您拥有的事件列表。 对于每个记录，请转换开始日期和结束日期，并检查它们是否满足您要查找的条件。
