Python:Efficient way to check if dictionary is empty or not [duplicate]

Answer 1

As far as I know the for loop uses the iter function and you should not mess with a structure while iterating over it.

Does it have to be a dictionary? If you use a list something like this might work:

while len(my_list) > 0:
    #get last item from list
    key, value = my_list.pop()
    #do something with key and value
    #maybe
    my_list.append((key, value))

Note that my_list is a list of the tuple (key, value). The only disadvantage is that you cannot access by key.

EDIT: Nevermind, the answer above is mostly the same.
