如何将具有相同键的对象组合在一起而不覆盖这些值？

def combine_objects(objects):
    result = {}
    for obj in objects:
        key = obj['key']
        value = obj['value']
        if key in result:
            # 合并值，这里将值组成一个列表
            result[key].append(value)
        else:
            result[key] = [value]
    return result

# 示例数据
objects = [
    {'key': 'A', 'value': 1},
    {'key': 'B', 'value': 2},
    {'key': 'A', 'value': 3},
    {'key': 'C', 'value': 4},
    {'key': 'B', 'value': 5}
]

# 调用函数进行组合
combined_objects = combine_objects(objects)

# 打印结果
for key, values in combined_objects.items():
    print(f"{key}: {values}")

A: [1, 3]
B: [2, 5]
C: [4]
