我有一些类似于此的django代码(这是python 2.7.1)
try:
a = some_model.objects.get(some_field='foo') #this could except if for some reason it doesn't exist
method_that_throws_exception() #it won't reach this if we get a DoesNotExist
except some_model.DoesNotExist:
#if it doesn't exist create it then try again
a = some_model.objects.create(....)
try:
method_that_throws_exception() #this time lets say another exception is raised by method
print 'this should not print right?'
except Exception as e:
logging.error("error msg here")
问题是“这不应该打印”的行仍在打印中。我很困惑。我觉得我可能忽略了一些非常简单的事情,但目前可能有一些隧道视野。提前谢谢。
更新:如果我删除嵌套的try块,则在调用抛出异常的方法下面的打印仍会打印。

我想通了,这个方法里面有一个试试块,但是我没有提出来。在method_that_throws_exception()中的异常处理程序中添加raise修复了我的问题。
