问题描述
有没有什么价值重新提出异常，没有其他代码之间？
Is there any value to re-raising an exception with no other code in between?
try:
#code
except Exception:
raise
我最近正在看一些代码，看到几个这样的块，除了块外没有额外的，但另一个加注。我假设这是一个错误的决策，我是对的吗？
I was recently looking through some code and saw a few blocks like these with nothing extra in the except block but another raise. I assume this was a mistake and poor decision making, am I right?
推荐答案
之前我已经看过类似的代码一套）可怕的VB.NET项目。或者意图是捕获和记录例外，而没有回来完成日志记录，或者他们听到你必须捕获例外，实现了这个功能，而别人决定应该重新加注。
I've seen similar code before in a (set of) horrible VB.NET projects. Either the intent was to catch and log exceptions, without ever coming back to finish the logging, or they heard "you must catch exceptions", implemented this functionality, and someone else decided it should just re-raise.
上述代码没有任何好处。
There is no benefit to the above code.
