How to remove dictionary from list that is not empty completely?

I have a list that looks like this: 

 [{'name':'bob'},{'name':''},{'name':'test2'}]

The dictionary object is not really empty in the list, so how do I remove this 'empty' object that is not really empty? the new list should look like this:

 [{'name':'bob'},{'name':'test2'}]

I have tried:

[i for i in mylist if i]

but since the dictionary object is not completely empty I am not able to drop it, I think.

edit:

I put the below code in my JSON data clean up process like so:

for json in list:
   try:
      name = extract_json
      name = [i for i in name if len(i["name"]) > 0]
   except:
      name = None

I want to do the list clean only if it is needed.

You can try this. It is foolproof for dicts with more than one key and also data types other than string:

mylist = [{'name':'bob'},{'name':''},{'name':'test2'}]
new_list = [d for d in mylist if any(d.values())]

You need to test the name key of each dict, I would do it by checking the length of the name is greater than zero:

>>> d = [{'name':'bob'},{'name':''},{'name':'test2'}]
>>> [i for i in d if len(i["name"]) > 0]
[{'name': 'bob'}, {'name': 'test2'}]
