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)))))python dict remove duplicates where name are not the same
