在我的方法之一中，中断异常和执行异常即将到来。我像这样输入了 try catch 。

try{

  //my code
}catch(InterruptedException|ExecutionException e)

  Log.error(" logging it");
  throw new MonitoringException("it failed" , e)


//monitoringexception extends RunTimeException

同样在我的方法中，我抛出了 InterruptedException,ExecutionException

我在声纳中遇到严重错误 - 重新中断此方法或重新抛出“ InterruptedException”

有人知道怎么修这个东西吗。

请立即帮助。

函数名是否应该main()为空并且在函数本身内调用参数,或者将它们作为函数的输入是否可接受main(arg1, arg2, arg3)？

我知道它有效,但我想知道它是不是很糟糕的编程习惯.如果这是重复的道歉,但我看不出专门针对Python的问题.

我是编程新手，所以我遇到了这个麻烦。我升级了我的 pip，然后使用 pip list、ipython Notebook、jupyter Notebook 来使用 anaconda，所以在所有这些命令之后我得到了一个答案：

如果用户已经输入'tea'或't'为自己的选择,我该如何定义变量beverage.lower()为'tea'？因为

if beverage.lower()=='t'or beverage.lower()=='tea':
                beverage.lower()=='tea'

line对整个程序本身绝对没有任何影响？

while True:
        beverage=raw_input("What is your preferred beverage: coffee, or tea?")
        if beverage.lower() not in ('coffee','tea','t','c'):
            if beverage.lower()=='t'or beverage.lower()=='tea':
                beverage.lower()=='tea'
            elif beverage.lower()=='c'or beverage.lower()=='coffee':
                beverage.lower()=='coffee'
            print("Sorry! I didn't quite catch that. Please try again! (Note that you can use the letter 'c' or the letter 't' to denote coffee or tea respectively!)")
            continue
        else:
            print("Ah! Fantastic choice!")
            break

同样,我如何定义beverage.lower()作为另一个变量输入的用户？
