在python中生成15分钟的时间间隔数组

标签: python arrays python-2.7

我是python的新手。我正在尝试生成时间间隔数组。例如: time_array = ["2016-09-02T17:30:00Z", "2016-09-02T17:45:00Z", "2016-09-02T18:00:00Z", "2016-09-02T18:15:00Z", "2016-09-02T18:30:00Z", "2016-09-02T18:45:00Z"] 它应该在祖鲁时间创造如上所述的元素,直到每天晚上9点。 2.也应该为下一天和下一天生成元素 3.开始时间从上午7点开始 - 编辑时间晚上9点, 如果current_time是> start_time然后生成15分钟的时间间隔阵列,直到晚上9点。然后为第二天和第二天生成。 间隔时间应该是7:00,7:15 ..不是在7:12,8:32

这里是您使用的通用datetime_range

代码

from datetime import datetime, timedelta

def datetime_range(start, end, delta):
    current = start
    while current < end:
        yield current
        current += delta

dts = [dt.strftime('%Y-%m-%d T%H:%M Z') for dt in 
       datetime_range(datetime(2016, 9, 1, 7), datetime(2016, 9, 1, 9+12), 
       timedelta(minutes=15))]

print(dts)

输出

  

[&#39; 2016-09-01 T07:00 Z&#39;,&#39; 2016-09-01 T07:15 Z&#39;,&#39; 2016-09-01 T07:30 Z&#39;,&#39; 2016-09-01 T07:45 Z&#39;,&#39; 2016-09-01 T08:00 Z&#39;,&#39; 2016-09-01 T08: 15 Z&#39;,&#39; 2016-09-01 T08:30 Z&#39;,&#39; 2016-09-01 T08:45 Z&#39;,&#39; 2016-09-01 T09 :00 Z&#39;,&#39; 2016-09-01 T09:15 Z&#39;,&#39; 2016-09-01 T09:30 Z&#39;,&#39; 2016-09-01 T09:45 Z&#39; ......]

查看数据文件,您应该使用内置的python日期时间对象。然后strftime格式化您的日期。

从广义上讲,您可以将下面的代码修改为您想要的许多日期时间 首先创建一个开始日期。

Today= datetime.datetime.today()

用您想要的任意数量的时间间隔替换100。

date_list = [Today + datetime.timedelta(minutes=15*x) for x in range(0, 100)]

最后,使用下面的代码以您希望的方式格式化列表。

datetext=[x.strftime('%Y-%m-%d T%H:%M Z') for x in date_list]

以下是Pandas解决方案:

import pandas as pd

l = (pd.DataFrame(columns=['NULL'],
                  index=pd.date_range('2016-09-02T17:30:00Z', '2016-09-04T21:00:00Z',
                                      freq='15T'))
       .between_time('07:00','21:00')
       .index.strftime('%Y-%m-%dT%H:%M:%SZ')
       .tolist()
)

输出:

答案 3 :(得分:2)

我将提供处理时区的解决方案,因为问题是生成日期和时间,您可以随后设置时区。

您有一个开始日期,开始和结束时间(每天),以及这些日期时间的间隔(以分钟为单位)。我们的想法是创建一个代表时间间隔的timedelta对象并重复更新日期时间,直到我们到达结束时间,然后我们提前一天并将时间重置为初始时间并重复。

一个简单的实现可能是:

def make_dates(start_date, number_of_days, start_time, end_time, interval, timezone):
    if isinstance(start_date, datetime.datetime):
        start_date = start_date.date()
    start_date = datetime.datetime.combine(start_date, start_time)
    cur_date = start_date
    num_days_passed = 0
    step = datetime.timedelta(seconds=interval*60)

    while True:
        new_date = cur_date + step
        if new_date.time() > end_time:
            num_days_passed += 1
            if num_days_passed > number_of_days:
                break
            new_date = start_date + datetime.timedelta(days=num_days_passed)
        ret_date, cur_date = cur_date, new_date
        yield ret_date

In [31]: generator = make_dates(datetime.datetime.now(), 3, datetime.time(hour=17), datetime.time(hour=19), 15, None)

In [32]: next(generator)
Out[32]: datetime.datetime(2016, 9, 2, 17, 0)

In [33]: next(generator)
Out[33]: datetime.datetime(2016, 9, 2, 17, 15)

In [34]: list(generator)
Out[34]: 
[datetime.datetime(2016, 9, 2, 17, 30),
 datetime.datetime(2016, 9, 2, 17, 45),
 datetime.datetime(2016, 9, 2, 18, 0),
 datetime.datetime(2016, 9, 2, 18, 15),
 datetime.datetime(2016, 9, 2, 18, 30),
 datetime.datetime(2016, 9, 2, 18, 45),
 datetime.datetime(2016, 9, 2, 19, 0),
 datetime.datetime(2016, 9, 3, 17, 0),

 datetime.datetime(2016, 9, 3, 18, 45),
 datetime.datetime(2016, 9, 3, 19, 0),
 datetime.datetime(2016, 9, 4, 17, 0),
 datetime.datetime(2016, 9, 4, 17, 15),
 datetime.datetime(2016, 9, 4, 17, 30),
 datetime.datetime(2016, 9, 4, 17, 45),
 datetime.datetime(2016, 9, 4, 18, 0),
 datetime.datetime(2016, 9, 4, 18, 15),
 datetime.datetime(2016, 9, 4, 18, 30),
 datetime.datetime(2016, 9, 4, 18, 45),
 datetime.datetime(2016, 9, 4, 19, 0),
 datetime.datetime(2016, 9, 5, 17, 0),
 datetime.datetime(2016, 9, 5, 17, 15),
 datetime.datetime(2016, 9, 5, 17, 30),
 datetime.datetime(2016, 9, 5, 17, 45),
 datetime.datetime(2016, 9, 5, 18, 0),
 datetime.datetime(2016, 9, 5, 18, 15),
 datetime.datetime(2016, 9, 5, 18, 30),
 datetime.datetime(2016, 9, 5, 18, 45)]

获得日期时间后,您可以使用strftime方法将其转换为字符串。

答案 4 :(得分:2)

以下是使用任意日期时间的示例

from datetime import datetime

start = datetime(1900,1,1,0,0,0)
end = datetime(1900,1,2,0,0,0)

现在您需要获取startend

之间的timedelta(两个日期或时间之间的差异。)
seconds = (end - start).total_seconds()

定义15分钟间隔

from datetime import timedelta

step = timedelta(minutes=15)

迭代秒数范围,时间差为15分钟(900秒)并将其加总为start

array = []
for i in range(0, int(seconds), int(step.total_seconds())):
    array.append(start + timedelta(seconds=i))

print array
[datetime.datetime(1900, 1, 1, 0, 0),
datetime.datetime(1900, 1, 1, 0, 15),
datetime.datetime(1900, 1, 1, 0, 30),
datetime.datetime(1900, 1, 1, 0, 45),
datetime.datetime(1900, 1, 1, 1, 0),
...

最后,您可以将datetime对象格式化为str表示。

array = [i.strftime('%Y-%m-%d %H:%M%:%S') for i in array]

print array
['1900-01-01 00:00:00',
 '1900-01-01 00:15:00',
 '1900-01-01 00:30:00',
 '1900-01-01 00:45:00',
 '1900-01-01 01:00:00',
...

您可以在第一次迭代时格式化datetime对象。但它可能会伤害你的眼睛

array.append((start + timedelta(seconds=i)).strftime('%Y-%m-%d %H:%M%:%S'))
