Answers for "python how to stop duplicate values in a dictionary"

python remove duplicates from list of dict

# set the dict to a tuple for hashability, then use {} for set literal and retrn each item to dict. 
[dict(t) for t in {tuple(d.items()) for d in l}]
# using two maps()
list(map(lambda t: dict(t), set(list(map(lambda d: tuple(d.items()), l)))))

create dictionary without removing duplicates from dataframe

df.groupby(level=0).apply(lambda x: x.to_dict('r')).to_dict()
# {'bob': [{'age': 20, 'name': 'bob'}, {'age': 30, 'name': 'bob'}],
#  'jim': [{'age': 25, 'name': 'jim'}]}
