关于long类型的理解存在疑点

[NB-Dragon]

根据你的文档BasicObject/long，我使用64位版本的Python 3.9.12进行验证。 验证代码如下

import ctypes
data = 0
for index in range(50):
    data = data * 2 + 1
    data_id, hex_list = id(data) + 24, []
    for byte_index in range(8):
        hex_list.append(ctypes.c_ubyte.from_address(data_id + byte_index).value)
    hex_list = ["{:02x}".format(item) for item in hex_list]
    print("{:064b}".format(data), " ".join(hex_list))

其对应的输出结果为

0000000000000000000000000000000000000000000000000000000000000001 01 00 00 00 00 00 00 00

其结果表明了在int的存储范围中(4个字节)，其最大能记录的数据是(1<<30) -1，32位比特的前两位作为特殊用途保留下来。而非你文档所说的(1个保留位+15个数据位)*N组，请作者重新验证后给予回复，谢谢
