使用自定义哈希函数创建一个namedtuple

from collections import namedtuple

MyTuple = namedtuple('MyTuple', ['field1', 'field2', 'field3'])

def custom_hash(obj):
    if isinstance(obj, MyTuple):
        return hash((obj.field1, obj.field2, obj.field3))
    return hash(obj)

my_tuple = MyTuple(1, 'hello', [1, 2, 3])

hash_value = custom_hash(my_tuple)
