asyncio 오류 문의 드립니다.

p-chapter07-01.py 실행시 아래와 같이 오류가 발생합니다.

SSL 관련 인증 오류 인 것 같은데 어떻게 해야할 지 모르겠습니다.

지금까지 잘 되었는데, 마지막 Chapter에서 오류가 발생하네요.. ㅠ.ㅠ

+ 사용환경 

    + OS : MacOS 12.0.1 (Monterey)

    + Python Ver. : 3.10

+ Error Message 

urllib.error.URLError: <urlopen error [SSL: CERTIFICATE_VERIFY_FAILED] certificate verify failed: self signed certificate in certificate chain (_ssl.c:997)>

+ Error Log
