在Python中删除列表中的重复字典

def dict_to_tuple(d):
    return tuple(sorted(d.items()))

def remove_duplicates(lst):
    seen = set()
    result = []
    for d in lst:
        t = dict_to_tuple(d)
        if t not in seen:
            seen.add(t)
            result.append(d)
    return result

# 示例
lst = [{'a': 1, 'b': 2}, {'b': 2, 'a': 1}, {'c': 3}]
print(remove_duplicates(lst))

from functools import reduce

    return reduce(lambda x, y: x + [y] if y not in x else x, lst, [])

# 示例
lst = [{'a': 1, 'b': 2}, {'b': 2, 'a': 1}, {'c': 3}]
print(remove_duplicates(lst))
