从第n个列表项创建字典

def create_dict_from_list(n, list_items):
    # 确定第n个列表项的数据结构和内容
    item = list_items[n-1]

    # 创建一个空字典
    dictionary = {}

    # 遍历第n个列表项，将每个键值对添加到字典中
    for pair in item:
        key = pair[0]
        value = pair[1]
        dictionary[key] = value

    # 返回创建好的字典
    return dictionary

# 示例数据
list_items = [
    [("name", "John"), ("age", 25)],
    [("name", "Jane"), ("age", 30)],
    [("name", "Tom"), ("age", 35)]
]

# 创建字典
n = 3
result = create_dict_from_list(n, list_items)
print(result)
