Python:如何创建嵌套容器的哈希

import hashlib

def create_nested_hash(container, hash_type):
    hash_obj = hashlib.new(hash_type)
    for item in container:
        if isinstance(item, list):
            for sub_item in item:
                hash_obj.update(str(sub_item).encode('utf-8'))
        else:
            hash_obj.update(str(item).encode('utf-8'))
    return hash_obj.hexdigest()

# 示例用法
nested_list = [['a', 'b', 'c'], ['d', 'e', 'f']]
hash_type = 'sha256'

nested_hash = create_nested_hash(nested_list, hash_type)
print(nested_hash)
