如何根据值对列表进行分组，而不会导致属性错误

def group_by_attribute(lst, attribute):
    grouped_dict = {}
    for item in lst:
        value = item.get(attribute)  # 获取元素的属性值
        if value not in grouped_dict:
            grouped_dict[value] = [item]
        else:
            grouped_dict[value].append(item)
    return grouped_dict

# 示例数据
data = [
    {"name": "Alice", "age": 25, "gender": "female"},
    {"name": "Bob", "age": 30, "gender": "male"},
    {"name": "Charlie", "age": 25, "gender": "male"},
    {"name": "Dave", "age": 30, "gender": "male"},
    {"name": "Eve", "age": 25, "gender": "female"}
]

# 根据年龄进行分组
grouped_data = group_by_attribute(data, "age")
print(grouped_data)

{
    25: [
        {"name": "Alice", "age": 25, "gender": "female"},
        {"name": "Charlie", "age": 25, "gender": "male"},
        {"name": "Eve", "age": 25, "gender": "female"}
    ],
    30: [
        {"name": "Bob", "age": 30, "gender": "male"},
        {"name": "Dave", "age": 30, "gender": "male"}
    ]
}
