1、解析 python try是用来捕获异常。如果某段代码发生了错误，可以用try来运行这段代码；如果try的代码块出现错误，则try代码省下的代码不会继续执行，而是直接跳转到catch代码块，catch就是错误处理代码块。2、案例 （1）捕获异常的方式 try:a = b b = c except Exception,data:print Exception,:,...
Using a tuple of exception types is a simple and concise way to catch multiple exceptions in a single except block in Python. When an exception occurs in the try block, Python checks if the exception is an instance of any of the exception types listed in the tuple. If so, the correspond...
However, at times, we may want a generalexceptblock that can catch all exceptions. It is very simple to implement this. If we do not mention any specific exception in theexceptblock, then it catches any exception which might occur.
不管 try 块中的代码是否出现异常,也不管哪一个 except 块被执行,甚至在 try 块或 except 块中执行了 return 语句,finally 块总会被执行。 Python 完整的异常处理语法结构如下: try: #业务实现代码 except SubException as e: #异常处理块1 ... except SubException2 as e: #异常处理块2 ... else: #正...
