1. 获取时间戳

datetime(python3)

import datetime
dt = datetime.datetime.now()
print(dt.timestamp())  # 1669275509.282593

import datetime
import calendar
dt = datetime.datetime.now()
print(calendar.timegm(dt.timetuple()))  #1669304413

import time
tm = time.localtime()
print(time.strftime("%Y-%m-%d %H:%M:%S", tm))  #2020-04-13 07:19:09

dt = datetime.datetime.now()
print(dt) #2020-04-13 08:19:24.995891

date_time = now.strftime("%Y-%m-%d %H:%M:%S")
print("date and time:",date_time)

import datetime
dt = datetime.datetime.fromtimestamp(1586765847)
print(dt)  #2020-04-13 08:17:27

import time

import time
tm = time.strptime('2020-04-13', "%Y-%m-%d")
tmsp = time.mktime(tm)  # 1586707200.0

dt = datetime.datetime.strptime('2022-11-24 16:04:11', "%Y-%m-%d %H:%M:%S")
print(dt.timestamp())  #1669277051.0
