常用模块之time模块

import time
#获取当前的时间戳  浮点型
floatStamp = time.time()
print(floatStamp)
#获取当前的时间戳  整型
intStamp = int(time.time())
print(intStamp)
#从返回的浮点数的时间戳转成时间元组 
localtime = time.localtime()
print(localtime) #time.struct_time(tm_year=2018, tm_mon=11, tm_mday=20, tm_hour=23, tm_min=11, tm_sec=57, tm_wday=1, tm_yday=324, tm_isdst=0)
#将时间字符串解析成时间元组
tupleTime = time.strptime('2018-11-20 23:40:50','%Y-%m-%d %H:%M:%S')
print(tupleTime) # time.struct_time(tm_year=2018, tm_mon=11, tm_mday=20, tm_hour=23, tm_min=40, tm_sec=50, tm_wday=1, tm_yday=324, tm_isdst=-1)
#将时间戳转成格式化时间
timeFormat1 = time.asctime(time.localtime(time.time()))
print(timeFormat1) # Thu Apr  7 10:05:21 2016
timeFormat2 = time.strftime('%Y-%m-%d %H:%M:%S',time.localtime(time.time()))
print(timeFormat2) # 2018-11-20 23:23:18
#将格式化时间转成时间戳
formatTime = '2018-11-20 23:23:18'
tf = int(time.mktime(time.strptime(formatTime,'%Y-%m-%d %H:%M:%S')))
print(tf) # 1542727398
#时间元组转成时间戳【浮点时间戳】 (tm_year,tm_month,tm_day,tm_hour,tm_min,tm_sec,tm_wday,tm_isdst)
t = (2009, 2, 17, 17, 3, 38, 1, 48, 0)
