Appending the values list in dictionary

I have dictionary, which contains different list.

I want toc combine data in different dictionary appending values of similar keys in it.

{'mental_issue': ['stress', 'live in fear', 'stomach curl', 'wracked by stress', 'chest tighten']}
{'sexual_abuse': ['stalking'], 'mental_issue': ['abuse', 'pica']}
{}
{'verbal_abuse': ['in the face'], 'mental_issue': ['abuse']}
{}
{'mental_issue': ['abuse']}
{'mental_issue': ['abuse']}
{'mental_abuse': ['name call'], 'mental_issue': ['abuse']}
{}
{'mental_issue': ['broken jaw', 'abuse', 'heart broken']}
{'mental_issue': ['live in fear']}
{'mental_issue': ['abuse', 'trauma']}
{'mental_issue': ['nightmares', 'abuse', 'panic attack']}
{'mental_issue': ['stress']}
{'mental_issue': ['severe']}
{'mental_issue': ['nightmares', 'bad emotional state']}
{'sexual_abuse': ['rape'], 'mental_issue': ['stress', 'paranoia']}
{'mental_issue': ['fracturing both my', 'both my knees']}
{'mental_issue': ['abuse']}
{'sexual_abuse': ['rape'], 'verbal_abuse': ['kicking'], 'mental_issue': ['nightmares']}

I want to combine values of all issues like mental_abuse should have all mental aboses from all dictionary.

I wrote this logic -

sexual_abuse_list = []
d = {'sexual_abuse': ['rape'], 'verbal_abuse': ['kicking'], 'mental_issue': ['nightmares']}
if 'sexual_abuse' in d:
    for item in d['sexual_abuse']:
            sexual_abuse_list.append(item)

Is this correct logic? or any better logic can be written?

Using collections.defaultdict

Ex:

from collections import defaultdict


lst = [{'mental_issue': ['stress', 'live in fear', 'stomach curl', 'wracked by stress', 'chest tighten']},
{'sexual_abuse': ['stalking'], 'mental_issue': ['abuse', 'pica']},
{},
{'verbal_abuse': ['in the face'], 'mental_issue': ['abuse']},
{},
{'mental_issue': ['abuse']},
{'mental_issue': ['abuse']},
{'mental_abuse': ['name call'], 'mental_issue': ['abuse']},
{},
{'mental_issue': ['broken jaw', 'abuse', 'heart broken']},
{'mental_issue': ['live in fear']},
{'mental_issue': ['abuse', 'trauma']},
{'mental_issue': ['nightmares', 'abuse', 'panic attack']},
{'mental_issue': ['stress']},
{'mental_issue': ['severe']},
{'mental_issue': ['nightmares', 'bad emotional state']},
{'sexual_abuse': ['rape'], 'mental_issue': ['stress', 'paranoia']},
{'mental_issue': ['fracturing both my', 'both my knees']},
{'mental_issue': ['abuse']},
{'sexual_abuse': ['rape'], 'verbal_abuse': ['kicking'], 'mental_issue': ['nightmares']}]

d = defaultdict(list)

for i in lst:
    for k, v in i.items():
        d[k].extend(v)
print(d)

Output:

defaultdict(<type 'list'>, {'sexual_abuse': ['stalking', 'rape', 'rape'], 'verbal_abuse': ['in the face', 'kicking'], 'mental_abuse': ['name call'], 'mental_issue': ['stress', 'live in fear', 'stomach curl', 'wracked by stress', 'chest tighten', 'abuse', 'pica', 'abuse', 'abuse', 'abuse', 'abuse', 'broken jaw', 'abuse', 'heart broken', 'live in fear', 'abuse', 'trauma', 'nightmares', 'abuse', 'panic attack', 'stress', 'severe', 'nightmares', 'bad emotional state', 'stress', 'paranoia', 'fracturing both my', 'both my knees', 'abuse', 'nightmares']})
