pass Separating the exception from the variable with a comma will still work in Python 2.6 and 2.7, but is now deprecated; now you should be using as.
Up to this point, you’ve learned several ways of dealing with multiple possible exceptions. However, you’ve only ever caught one out of the bunch. In the final section, you’ll learn how to catch each member in a group of exceptions. Remove ads ...

处理异常的标准方法就是使用try...except语句。这一点其实比较类似于Java中的try...catch语句,事实上,大部分语言都有类似的捕捉异常的方法。 通常来说,可能产生异常的代码应该被try语句囊括进去,如果报异常的就会立即停止try语句中的剩余代码,并执行except语句中的代码。

As a result, in the above code, the IndexError exception is not being caught by the except statement; rather, the exception instead ends up being bound to a parameter named IndexError. Python code mistakes like this are common. The proper way to catch multiple exceptions in an except ...
To add multiple Exceptions to the except clause, you need to pass them as parenthesized tuple as the first argument. The second argument is an optional name, which when supplied will bind the Exception instance that has been raised. Example, some_list = [1, 2, 3] try: # This should ...
In some situations, you want to react the same way, e.g. catching multiple network-related exceptions and just say "network was stupid" message. What you are looking for is: except (socket.error, urllib2.URLError, httplib.HTTPException) as e: # when you want to log the error, you ...
