In kafka/conn.py, there is the following statement

self._ssl_context = ssl.SSLContext(ssl.PROTOCOL_SSLv23)

ssl.PROTOCOL_SSLv23 is an alias of ssl.PROTOCOL_TLS and has been deprecated since Python 3.6.

Further, ssl.PROTOCOL_TLS is deprecated since Python 3.10; the generic TLS protocol constant is deprecated in favor of ssl.PROTOCOL_TLS_CLIENT and ssl.PROTOCOL_TLS_SERVER.
