python UNIX_TIMESTAMP時間處理

from datetime import datetime
import time
int(time.mktime(rm.start_time.timetuple()))
 datetime.fromtimestamp(time.time())
rf.start_time + timedelta(0, math.ceil(diff.total_seconds()/(3600*rf.period))*3600*rf.period)

擷取按月或者小時位移時間

def getlastday(datetimeobj):
    year= datetimeobj.year
    month = datetimeobj.month + 1
    if month>12:
        year = year + 1
        month=1        
    return datetime(year, month, 1) - timedelta(1)

def getSendTime(period, start_time):
    datenow = datetime.now()
    nextTime = preTime = start_time
    if period > 0 and period < 1000:         
        diff = datetime.now() - start_time
        nextTime = start_time + timedelta(0, math.ceil(diff.total_seconds()/(3600*period))*3600*period)
        preTime = start_time + timedelta(0, math.floor(diff.total_seconds()/(3600*period))*3600*period)
    if period == 1001:
        if datenow.day>start_time.day:            
            preTime = datetime(datenow.year, datenow.month, start_time.day)
            nextTime = getlastday(getlastday(datenow)+timedelta(1))
            if nextTime.day > start_time.day:
                nextTime = datetime(nextTime.year, nextTime.month, start_time.day)
        else:
            preTime = getlastday(datetime(datenow.year, datenow.month, 1) - timedelta(1))
            if preTime.day > start_time.day:
                preTime = datetime(preTime.year, preTime.month, start_time.day)
            nextTime = getlastday(datenow)
            if nextTime.day > start_time.day:
                nextTime = datetime(nextTime.year, nextTime.month, start_time.day)
    
    return  preTime, nextTime

排序

 reportMetaPeriodInfo.sort(lambda p1, p2:cmp(p1['k'], p2['k']))

擷取ip

import socket

s = socket.socket(socket.AF_INET, socket.SOCK_DGRAM)
        s.connect(('8.8.8.8', 0))
        localIP=s.getsockname()[0]
