我有以下代码
import datetime
#import numpy as np
import jacks_toolbox.getHistoricalData as dt
# ------------------------------------------------------------------------------
# Config
# ------------------------------------------------------------------------------
rolling_time = 15
num_days = 20
Start = "2016-09-27 00:00:00"
End = "2016-10-14 23:00:00"
settleTimeStr = "2016-10-14 14:00:00"
# ------------------------------------------------------------------------------
# Start execution
# ------------------------------------------------------------------------------
# Get a window of data from MySQL and plot it
startTime = datetime.datetime.strptime(Start, "%Y-%m-%d %H:%M:%S")
endTime = datetime.datetime.strptime(End, "%Y-%m-%d %H:%M:%S")
settleTime = datetime.datetime.strptime(settleTimeStr, "%Y-%m-%d %H:%M:%S")
print "Start time: " + startTime.strftime("%Y-%m-%d %H:%M:%S")
print "End time: " + endTime.strftime("%Y-%m-%d %H:%M:%S")
print "Settle time: " + settleTime.strftime("%Y-%m-%d %H:%M:%S")
data = dt.getHistoricalDataByTime(startTime, endTime, 5)
settles = dt.getHistoricalDataByTime(startTime, settleTime, 5)
print settles[::1425]
我正在尝试对其进行索引，以便从我的开始时间开始每24小时打印一次，但目前正在打印以下内容：
Start time: 2016-09-27 00:00:00
End time: 2016-10-14 23:00:00
Settle time: 2016-10-14 14:00:00

出于某种原因，这是我加入一分钟，然后是30分钟，我试图将其编入索引，我不知道为什么会这样。最初我从1440开始，因为那是24 * 60，但注意到第一组时间是15分钟，所以我转到1425，这就是我得到的。任何帮助/建议将不胜感激。
