python 时间转换 time / datetime

time 库

 1 import time   2 # 构造数组时间，参数对应年月日时分秒，后面两个参数为星期几和年中的第几天，任意填即可，转换到时间戳时不影响结果，想获得的话可以转到时间戳再转回来  3 timeArray = time.struct_time([2022, 4, 20, 1, 2, 3, 0, 0, -1])  4 # 获取参数  5 timeArray.tm_year  6 timeArray.tm_mon  7 timeArray.tm_mday  8 timeArray.tm_hour  9 timeArray.tm_min 10 timeArray.tm_sec 11 timeArray.tm_wday 12 # 当地时间 13 timeStamp = time.time() 14 timeArray = time.localtime() 15 # GMT/UTC时间 16 timeArray = time.gmtime() 17 # 数组时间 -> 时间戳 18 timeStamp = time.mktime(timeArray) 19 # 数组时间 -> 字符串时间 20 timeString = time.strftime(%Y-%m-%d %H:%M:%S, timeArray) 21 # 时间戳 -> 数组时间 22 timeArray = time.localtime(timeStamp) 23 # 字符串时间 -> 数组时间 24 timeArray = time.strptime(2020-01-01 23:59:59, %Y-%m-%d %H:%M:%S)

datetime 库

import datetime # 构造数组时间 timeArray = datetime.datetime(year=2022, month=4, day=20, hour=1, minute=2, second=3, microsecond=4) # 获取参数 timeArray.year timeArray.month timeArray.day timeArray.hour timeArray.minute timeArray.second timeArray.microsecond # 当地时间 timeArray = datetime.datetime.now() # GMT/UTC时间 timeArray = datetime.datetime.utcnow() # 时间偏移 timeArray = datetime.datetime.utcnow() + datetime.timedelta(hours=8) # 数组时间 -> 时间戳 timeStamp = timeArray.timestamp() # 数组时间 -> 字符串时间 timeString = timeArray.strftime('%Y-%m-%d %H:%M:%S') # 时间戳 -> 数组时间 timeArray = datetime.datetime.fromtimestamp(timeStamp) # 字符串时间 -> 数组时间 timeArray = time.strptime(2020-01-01 23:59:59, %Y-%m-%d %H:%M:%S)
