python 日期、时间

1、字符类型的时间 转为 时间数组

t1 = '2013-10-10 23:40:00'
timeArray = time.strptime(t1, "%Y-%m-%d %H:%M:%S")

# 结果如下
time.struct_time(tm_year=2013, tm_mon=10, tm_mday=10, tm_hour=23, tm_min=40, tm_sec=0, tm_wday=3, tm_yday=283, tm_isdst=-1)

2、字符类型的时间 转为其它显示格式

t2 = "2013-10-10 23:40:00"
# 转为数组
timeArray = time.strptime(t2, "%Y-%m-%d %H:%M:%S")
# 转为其它显示格式
otherStyleTime = time.strftime("%Y/%m/%d %H:%M:%S", timeArray)
print otherStyleTime # 2013/10/10 23:40:00

3、获取当前时间戳

# time获取当前时间戳
now = int(time.time()) 
timeArray = time.localtime(now)

转换成需要的格式

otherStyleTime = time.strftime("%Y--%m--%d %H:%M:%S", timeArray)

4、datetime获取当前时间，数组格式
now = datetime.datetime.now()
print now
otherStyleTime = now.strftime("%Y--%m--%d %H:%M:%S")

def getlogname():
    logfilename = time.strftime('%Y%m%d%H%M%S',time.localtime(time.time()))
    return logfilename

def getPresentTime():   
    now = datetime.datetime.now()
    #print(now)
    return now
