python时间转换
1、获取秒级时间戳与毫秒级时间戳
import timeimport datetime
t = time.time()
print(t) #原始时间数据‘
print(int(t))#秒级时间戳
print(int(round(t * 1000)))#毫秒级时间戳
nowTime =lambda:int(round(t * 1000))
print(nowTime());#毫秒级时间戳，基于lambda
print(datetime.datetime.now().strftime('%Y-%m-%d %H:%M:%S'))#日期格式化
返回
1499825149.26
1499825149
1499825149257
1499825149257

2、将字符串转为秒级时间戳
dt ='2018-01-01 10:40:30'
ts = int(time.mktime(time.strptime(dt,"%Y-%m-%d %H:%M:%S")))
print(ts)
返回
1514774430
3、将字符串转为日期结构
dt ='2018-01-01 10:40:30'
ts = time.strptime(dt,"%Y-%m-%d %H:%M:%S")
print(ts)
返回
time.struct_time(tm_year=2018, tm_mon=6, tm_mday=24, tm_hour=10, tm_min=20, tm_sec=30, tm_wday=6, tm_yday=175, tm_isdst=-1)
4、将秒级时间戳转为日期
ts = 1515774430
dt = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime(ts))
print(dt)
返回
2018-01-13 00:27:10
5、将当前秒级时间戳转为日期
dt = time.strftime("%Y-%m-%d %H:%M:%S", time.localtime())
print(dt)
