我想用dict检查相同键的列表，如果我有相同的键来合并dict

def merge_dicts_with_same_keys(dicts):
    merged_dict = {}
    
    for d in dicts:
        for key, value in d.items():
            if key not in merged_dict:
                merged_dict[key] = value
            else:
                if isinstance(merged_dict[key], list):
                    merged_dict[key].append(value)
                else:
                    merged_dict[key] = [merged_dict[key], value]
    
    return merged_dict

dicts = [
    {"a": 1, "b": 2},
    {"a": 3, "c": 4},
    {"b": 5, "d": 6},
    {"e": 7}
]

merged_dict = merge_dicts_with_same_keys(dicts)
print(merged_dict)

{'a': [1, 3], 'b': [2, 5], 'c': 4, 'd': 6, 'e': 7}
