那么就需要捕获Exception。 这就是Python的try except 的由来。当然如果你无比自信,那当我没说。 但是当你except 出来了Exception之后,你怎么办?直接print 吗? No!No!No! print 并不会将所有的错误路径给打印出来。 我们所需要的就是利用python的内置包的一个方法,伪代码如下: 代码语言:javascript 复制 importtra...

Python 中(至少)有两种错误:语法错误和异常(syntax errors和exceptions)。 1.1 错误 (1)语法错误,也被称作解析错误,无法通过python解释器的语法检测,必须在程序执行前就改正。比如: >>> while True print('Hello world') File "<stdin>", line 1, in ?
result=divide_numbers(10,0)print("结果:",result) 当num2=0 时,也就是除数为 0 时,抛出异常 ZeroDivisionError。 2.3.2 捕获异常(Catch Exception) 使用try-except语句可以捕获并处理异常。try块中的代码用于监视可能引发异常的操作。 如果在try块中引发了异常,控制权将转移到与异常匹配的except块,该块用于处...
在一个try-except(类似java中的try-catch)代码块中,except后会声明一种异常,声明的这种异常能处理所有该异常的子类异常(但是不包括他的父类异常)。 内部异常类可以被继承来定义新的异常类,并且建议程序员来通过继承Exception而不是BaseException来定义一个新的异常类。
In Python,try-exceptblocks can be used to catch and respond to one or multiple exceptions. In cases where a process raises more than one possible exception, they can all be handled using a singleexceptclause. There are several approaches for handling multiple exceptions in Python, the most com...
