在python中生成15分鍾的時間間隔數組

[英]Generating 15 minute time interval array in python

 原文  2016-09-02 17:40:53  8   6    python/ arrays/ python-2.7

問題描述

我正在嘗試生成時間間隔數組。 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"]
  1. 它應該在祖魯時間直到每天晚上9點創建上述元素。
  2. 也應該為下一個和后一天生成元素
  3. 開始時間從7:00 am-Ed time 9:00 pm，如果current_time> start_time，則生成15分鍾的時間間隔數組，直到9 pm。 然后為第二天和第二天生成2。間隔應該是這樣的7:00，7:15 ..不在7:12，8:32

這是供您使用的通用datetime_range 。

碼 

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)

輸出量

['2016-09-01 T07：00 Z'，'2016-09-01 T07：15 Z'，'2016-09-01 T07：30 Z'，'2016-09-01 T07：45 Z'，' 2016-09-01 T08：00 Z'，'2016-09-01 T08：15 Z'，'2016-09-01 T08：30 Z'，'2016-09-01 T08：45 Z'，'2016- 09-01 T09：00 Z'，'2016-09-01 T09：15 Z'，'2016-09-01 T09：30 Z'，'2016-09-01 T09：45 Z'...]

在查看數據文件時，您應該使用內置的python日期時間對象。 然后使用strftime格式化日期。

大致來說，您可以將下面的代碼修改為想要首先創建開始日期的任意多個日期時間。 

Today= datetime.datetime.today()

用任意數量的時間間隔替換100。 

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

最后，使用下面的代碼以所需的方式格式化列表。 

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

這是熊貓的解決方案： 

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()
)

輸出：

這是使用任意日期時間的示例 

from datetime import datetime

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

現在，您需要獲取start和end之間的時間增量（兩個日期或時間之間的差）。 

seconds = (end - start).total_seconds()

定義15分鍾間隔 

from datetime import timedelta

step = timedelta(minutes=15)

以15分鍾（900秒）的時間增量在秒的范圍內進行迭代，並將其相加以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，您可以將日期時間對象格式化為str表示形式。 

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時格式化datetime對象。 但這可能會傷害你的眼睛 

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

我將提供一種不處理時區的解決方案，因為問題是生成日期和時間，您可以在以后根據需要設置時區。

您有一個開始日期，開始和結束時間（每天），以及這些日期時間的間隔（以分鍾為單位）。 這個想法是創建一個代表時間間隔的timedelta對象，並重復更新日期時間，直到達到結束時間，然后再提前一天，然后將時間重置為初始時間，然后重復一次。

一個簡單的實現可以是： 

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, 15),
 datetime.datetime(2016, 9, 2, 18, 30),
 datetime.datetime(2016, 9, 2, 18, 45),

 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, 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)]

一旦有了日期時間，就可以使用strftime方法將其轉換為字符串。
