My list contains the following list of dictionary within dictionary:

list = [
    {'a':{'aa':11,'ab':12}},
    {'a':{'aa':21,'ab':22}},
    {'a':{'aa':31,'ab':32}}]

I am finding it difficult to access and compile all of the ‘aa’ data into a single list due it be nested within the ‘a’ dictionary.

I have tried creating a new list of dictionaries using a for loop, as per below, but I just get the same result. The goal of this was to extract the dictionary from within the ‘a’ dictionary and create a new list of unnested dictionaries, which is a state that I am familiar with.

#initialize empty list
empty_list = []

for new_list in list:
    empty_list.append(new_list)
