python的运行时错误称做异常
语法错误：软件的结构上有错误而导致不能被解释器或被编译器编译
逻辑错误：由于不完整或不合法的输入所致，也可能是逻辑无法生成，计算或者输出结果需要的过程无法执行等

python异常是一个对象，表示错误或意外情况
在python检测到一个错误时，将触发一个异常
python可以通过异常传导机制传递一个异常对象　发出一个异常情况出现的情况
程序员也在代码中自己触发异常(Python's runtime errors are called exceptions

Syntax error: there are errors in the structure of the software that can not be compiled by the interpreter or compiled by the compiler

Logical error: due to incomplete or unlawful input, it may also be impossible to generate logic, and the process of computing or output results cannot be executed.



An Python exception is an object that represents an error or an accident

When an error is detected in Python, an exception will be triggered

Python can send an exception object through an exception transmission mechanism to send out an abnormal situation

The programmer also triggers exceptions in the code itself)
