2019答案(适用于Windows):

如果你想要一个永久的UUID，在Windows上唯一地标识一台机器，你可以使用这个技巧:(复制自我在https://stackoverflow.com/a/58416992/8874388上的回答)。

from typing import Optional
import re
import subprocess
import uuid

def get_windows_uuid() -> Optional[uuid.UUID]:
    try:
        # Ask Windows for the device's permanent UUID. Throws if command missing/fails.
        txt = subprocess.check_output("wmic csproduct get uuid").decode()

        # Attempt to extract the UUID from the command's result.
        match = re.search(r"\bUUID\b[\s\r\n]+([^\s\r\n]+)", txt)
        if match is not None:
            txt = match.group(1)
            if txt is not None:
                # Remove the surrounding whitespace (newlines, space, etc)
                # and useless dashes etc, by only keeping hex (0-9 A-F) chars.
                txt = re.sub(r"[^0-9A-Fa-f]+", "", txt)

                # Ensure we have exactly 32 characters (16 bytes).
                if len(txt) == 32:
                    return uuid.UUID(txt)
    except:
        pass # Silence subprocess exception.

    return None

print(get_windows_uuid())

使用Windows API获取计算机的永久UUID，然后处理字符串以确保它是有效的UUID，最后返回一个Python对象(https://docs.python.org/3/library/uuid.html)，它为您提供了方便的方法来使用数据(如128位整数，十六进制字符串等)。

好运！

PS:子进程调用可能会被直接调用Windows内核/ dll的ctypes所取代。但对于我的目的，这个函数就是我所需要的。它能进行强有力的验证并产生正确的结果。

>>> import uuid

>>> # make a UUID based on the host ID and current time
>>> uuid.uuid1()
UUID('a8098c1a-f86e-11da-bd1a-00112444be1e')

>>> # make a UUID using an MD5 hash of a namespace UUID and a name
>>> uuid.uuid3(uuid.NAMESPACE_DNS, 'python.org')
UUID('6fa459ea-ee8a-3ca4-894e-db77e160355e')

>>> # make a random UUID
>>> uuid.uuid4()
UUID('16fd2706-8baf-433b-82eb-8c7fada847da')

>>> # make a UUID using a SHA-1 hash of a namespace UUID and a name
>>> uuid.uuid5(uuid.NAMESPACE_DNS, 'python.org')
UUID('886313e1-3b8a-5372-9b90-0c9aee199e5d')

>>> # make a UUID from a string of hex digits (braces and hyphens ignored)
>>> x = uuid.UUID('{00010203-0405-0607-0809-0a0b0c0d0e0f}')

>>> # convert a UUID to a string of hex digits in standard form
>>> str(x)

>>> # get the raw 16 bytes of the UUID
>>> x.bytes
'\x00\x01\x02\x03\x04\x05\x06\x07\x08\t\n\x0b\x0c\r\x0e\x0f'

>>> # make a UUID from a 16-byte string
>>> uuid.UUID(bytes=x.bytes)
UUID('00010203-0405-0607-0809-0a0b0c0d0e0f')

uuid模块提供了不可变的uuid对象(uuid类)和函数uuid1()、uuid3()、uuid4()、uuid5()，用于生成RFC 4122中指定的版本1、3、4和5 uuid。

如果您只想要一个唯一的ID，您可能应该调用uuid1()或uuid4()。注意，uuid1()可能会破坏隐私，因为它创建了一个包含计算机网络地址的UUID。uuid4()创建一个随机UUID。

UUID版本6和7 -用于现代应用程序和数据库(草案)rfc的新通用唯一标识符(UUID)格式-可从https://pypi.org/project/uuid6/获得

文档:

Python 2 Python 3

示例(适用于Python 2和3):

>>> import uuid

>>> # make a random UUID
>>> uuid.uuid4()
UUID('bd65600d-8669-4903-8a14-af88203add38')

>>> # Convert a UUID to a string of hex digits in standard form
>>> str(uuid.uuid4())
'f50ec0b7-f960-400d-91f0-c42a6d44e3d0'

>>> # Convert a UUID to a 32-character hexadecimal string
>>> uuid.uuid4().hex

此函数完全可配置，并根据指定的格式生成唯一的uid

例如:-[8,4,4,4,12]，这是提到的格式，它将生成以下uuid

LxoYNyXe-7hbQ-caJt-DSdU-PDAht56cMEWi

 import random as r

 def generate_uuid():
        random_string = ''
        random_str_seq = "0123456789abcdefghijklmnopqrstuvwxyzABCDEFGHIJKLMNOPQRSTUVWXYZ"
        uuid_format = [8, 4, 4, 4, 12]
        for n in uuid_format:
            for i in range(0,n):
                random_string += str(random_str_seq[r.randint(0, len(random_str_seq) - 1)])
            if n != 12:
                random_string += '-'
        return random_string

执行如下命令:

pip install uuid uuid6

然后运行你可以从uuid包中导入uuid1, uuid3, uuid4和uuid5函数，从uuid6包中导入uuid6和uuid7函数。

调用这些函数的输出示例如下(uuid3和uuid5除外，它们需要参数):

>>> import uuid, uuid6
>>> print(*(str(i()) for i in [uuid.uuid1, uuid.uuid4, uuid6.uuid6, uuid6.uuid7]), sep="\n")
