python try...exception 笔记 1,异常如果不被获取,它会一直往上抛,最后会被python解释器捕获,打印出错误信息,然后程序退出 2,要想程序继续执行,需要捕获异常 3,子函数里的异常会可以被上级捕获,异常可以 return 给上级 4,如果子程序没有捕捉异常,抛到上一级,直接进入上一级的异常,也就是上一级引用子程序后的...

We can also use thefinallyblock. It will execute code regardless of whether an exception occurs or not. try:a=1/0except:passfinally:print("Example") Output: Example In the above code, if thetryblock raises an error, theexceptblock will print the raised exception. ...
