分别处理特定（for io）异常(Handle specific (for io) exception separately)

 某些IO操作会产生一些错误。 重要的是，它不是一个例外，而是设定。 因此，我们设置了套接字错误，为文件io设置。 如何为不同的io操作处理没有交集的异常组？ 
 
 例如， OSError处理文件io错误和一些（？）套接字错误。 
 
 我只有一个解决方案：用try-except包装io操作并引发用户定义的异常。 
 
def foo():
    try:
        # some file io
    except:
        raise MyFileIOException(reason=sys.exc_info())

    try:
        # some socket io
    except:
        raise MySocketIOException(reason=sys.exc_info())

def bar():
    try:
        foo()
    except MyFileIOException as exc:
        # handle
    except MySocketIOException as exc:
        # handle
 
 有没有更优雅的解决方案？ 

Some IO operations produce some set of errors. It is important, that it is not one exception, but set. So, we have set for socket errors, set for file io. How to handle group of exceptions without intersection for different io operations?
 
For example, OSError handles file io errors and some(?) Socket errors.
 
I have only one solution: wrap io operations with try-except and raise user-defined exception.
 
def foo():
    try:
        # some file io
    except:
        raise MyFileIOException(reason=sys.exc_info())

    try:
        # some socket io
    except:
        raise MySocketIOException(reason=sys.exc_info())

def bar():
    try:
        foo()
    except MyFileIOException as exc:
        # handle
    except MySocketIOException as exc:
        # handle
 
Is there some better and elegant solution?
