如何从基于包含属性名称的另一个列表的列表中获取特定属性

def get_attribute_value(attribute_list, target_attribute):
    for inner_list in attribute_list:
        for attribute in inner_list:
            attribute_name = attribute[0]
            attribute_value = attribute[1]
            if attribute_name == target_attribute:
                return attribute_value
    return None

# 示例数据
attribute_list = [
    [('name', 'John'), ('age', 25), ('gender', 'male')],
    [('name', 'Emily'), ('age', 30), ('gender', 'female')],
    [('name', 'Tom'), ('age', 35), ('gender', 'male')]
]

# 获取属性值
target_attribute = 'age'
result = get_attribute_value(attribute_list, target_attribute)
print(result)  # 输出：25
