python 时间

1.字符串格式的时间转时间戳

import timea = "2022-04-19 08:51:31"#先转换成时间数组time_array = time.strptime(a,'%Y-%m-%d %H:%M:%S')print(time_array)#时间数组转时间戳time_stamp =int(time.mktime(time.strptime(a,'%Y-%m-%d %H:%M:%S')))print(time_stamp)

结果：

time.struct_time(tm_year=2022, tm_mon=4, tm_mday=19, tm_hour=8, tm_min=51, tm_sec=31, tm_wday=1, tm_yday=109, tm_isdst=-1)

1650329491

2.字符串时间戳转时间

import timetime_stamp = 1650329491#转时间数组time_array = time.localtime(time_stamp)print(time_array)#转时间time_time = time.strftime("%Y-%m-%d %H:%M:%S", time_array)print(time_time)

结果：

time.struct_time(tm_year=2022, tm_mon=4, tm_mday=19, tm_hour=8, tm_min=51, tm_sec=31, tm_wday=1, tm_yday=109, tm_isdst=0)

2022-04-19 08:51:31

3.常用的时间练习

import timeclass Time(): def now_time(self): return time.strftime('%H:%M:%S', time.localtime(time.time())) def now_date(self): return time.strftime('%Y-%m-%d', time.localtime(time.time())) def now_date_time(self): return time.strftime('%Y-%m-%d %H:%M:%S', time.localtime(time.time())) def now_time_stamp_10(self): return int(time.time()) def now_time_stamp_13(self): return int(time.time()*1000)if __name__ == '__main__': ss=Time() print(ss.now_time()) print(ss.now_date()) print(ss.now_date_time()) print(ss.now_time_stamp_10()) print(ss.now_time_stamp_13())
