def function():
    global global_values
    global_values: str = []

给出

SyntaxError: annotated name 'global_values' can't be global

这有什么原因吗？

我无法使用websocketsmodule连接到 websocket 。我有以下代码：

import asyncio, ssl
import websockets


headers= {
        'Accept-Encoding': 'gzip, deflate, br',
        'Accept-Language': 'en-US,en;q=0.9',
        'Cache-Control': 'no-cache',
        'Connection': 'Upgrade',
        'Host': ...,
        'Origin': ...,
        'Pragma': 'no-cache',
        'Upgrade': 'websocket',
        'User-Agent': 'Mozilla/5.0 (Windows NT 10.0; Win64; x64) AppleWebKit/537.36 (KHTML, like Gecko) Chrome/83.0.4103.106 Safari/537.36'
    }

async def hello():
    uri = ...
    async with websockets.connect(ssl=0,
                                  extra_headers=headers,
                                  origin="*",
                                  uri = uri) as websocket:
        pass

asyncio.get_event_loop().run_until_complete(hello())

我得到以下异常：

Traceback (most recent call last):
