try:do_something()except Exception:# THis will catch any exception!print("Something terrible happened") 为了合理准确的定义你的异常类,这里有一些规范与编程技巧,你可以做为参照: 必须继承 Exception类: class MyOwnError(Exception): pass 利用前面提到的BaseException.str: 它将传递给BaseException.init方法的...

Like any other exception, this will cause the code to crash if you don’t handle it. The except clause of your handler again contains a tuple of exceptions that you want to catch. You reference the exception, as before, by a variable named error. First, your handler prints the name of...
