[Django]-Possible to have multiple Python except statements when using try (without searching for a specific except)?

A bare except: will catch anything and everything, so it makes no sense to have a second except block in this case.

Possibly you wanted to put the code inside your first except block into another nested try/except block.

Note: Pokemon exception handling is considered bad coding style, and it’s better if you only try to catch the actual exceptions which you intend to handle – in this case, only catching the DoesNotExist should be sufficient.

You might consider using a loop to refactor this:

PostModels = {
    'postD': PostD,
    'postY': PostY,
    'postR': PostR,    
}

for k,Post in PostModels.items():
    try: 
        post = Post.objects.get(pk=pk)
    except Post.DoesNotExist:
        pass
    else:
        return PostReply.objects.filter(k=post)
else:
    # all 3 lookups failed, how do you want to handle this?

Since the first except will catch any exception raised from the try block, the only way “the above try and except statements fail” is if code in the first except block raises an exception. To catch that, you should wrap it directly with try/except:

def get_queryset(self)
    try:
        ...
    except:
        try:
            <<original first except-block here>>>
        except:
            <<original second except-block here>>>

Also, in general you should avoid bare except:.
