【Python】时间循环 / 日期循环

按天循环

def day_range(bgn,end):
    fmt = '%Y/%m/%d'
    begin=datetime.datetime.strptime(bgn,fmt)
    end=datetime.datetime.strptime(end,fmt)
    delta=datetime.timedelta(days=1)

    interval=int((end-begin).days) +1
   
    return [begin+delta*i for i in range(0,interval,1)]

按小时循环

def hour_range(bgn,end):
    fmt = '%Y/%m/%d %H:%M:%S'
    begin=datetime.datetime.strptime(bgn,fmt)
    end=datetime.datetime.strptime(end,fmt)
    delta=datetime.timedelta(hours=1)

    interval=int((end-begin).days*24+(end-begin).seconds/60/60) +1 
   
    return [begin+delta*i for i in range(0,interval,1)]

按分钟循环

def minute_range(bgn,end):
    fmt = '%Y/%m/%d %H:%M:%S'
    begin=datetime.datetime.strptime(bgn,fmt)
    end=datetime.datetime.strptime(end,fmt)
    delta=datetime.timedelta(minutes=10)

   interval=int((end-begin).days*24*60/10+(end-begin).seconds/60/10) +1  
   
    return [begin+delta*i for i in range(0,interval,1)]
