需要导入datetime库中的相应内容

from datetime import date, time, datetime, timedelta

日期

• 获取当前日期使用date.today()函数

  today = date.today()
  print(today)
  print(today.month)
  
  # 结果: 
  # 2020-06-29
  # 6
  

时间

• 获取当前时间使用datetime.today()函数

  current_datetime = datetime.today()
  print(current_datetime)
  
  # 结果: 2020-06-29 14:27:27.524896
  

运算

• 运算时不能简单加减, 要创建时间单位进行运算

  # 创建日期单位
  today = date.today()
  one_day = timedelta(days=-1)
  yesterday = today + one_day
  print(yesterday)
  
  # 结果: 2020-06-28
  

  # 创建时间单位
  current_datetime = datetime.today()
  eight_hours = timedelta(hours=8)
  eight_hours_later = current_datetime + eight_hours
  print(eight_hours_later)
  
  # 结果: 2020-06-29 22:31:30.992890
