Python实现获取【昨天】【今天】【明天】日期和shell交互

• 昨天

  from datetime import date, timedelta
  
  yesterday = (date.today() + timedelta(days=-1)).strftime("%Y-%m-%d")
  print(yesterday)
  

  

  今天

  

  明天

  from datetime import date, timedelta
  
  tomorrow = (date.today() + timedelta(days= 1)).strftime("%Y-%m-%d")
  print(tomorrow)
