[Python] Datetime 处理

定义变数为特定时间

t = datetime.datetime(2015, 1, 12, 23, 9, 12, 946118)

时间区间迭代

for single_date in (start_date + timedelta(n) for n in range(day_count)):    print ...

"月"加减

def monthdelta(d1, d2):    delta = 0    while True:        mdays = monthrange(d1.year, d1.month)[1]        d1 += timedelta(days=mdays)        if d1 <= d2:            delta += 1        else:            break    return delta   def monthadd(sourcedate,months):     month = sourcedate.month - 1 + months     year = sourcedate.year + month // 12     month = month % 12 + 1     day = min(sourcedate.day,monthrange(year,month)[1])     return date(year,month,day)     

datetime.strptime(d, "%Y%m%d%H%M%S").strftime("%Y%m%d")
