seaborn 설치 이후,
df = sns.load_dataset("iris")
를 입력했는데 다음과 같은 에러 메시지가 뜹니다.
원인이 무얼까요?

위의 방법이 안될 경우 https://raw.githubusercontent.com/mwaskom/seaborn-data/master/iris.csv 에서 다운 받은 다음 pandas
로 직접 읽어들이면 될것 같습니다.
import pandas
df = pandas.read_csv('iris.csv')
직접 파일을 받아서 위의 코드로 변환해서 이용하면 될 것 같습니다.

장주명님 답변 감사합니다. 위 방법으로 하셔도 되고요.
아마도 아나콘다로 파이썬을 설치하신게 아니라 직접 파이썬을 설치해서 사용하시는거 같습니다.
탐색기에서 Python 을 검색하시면 아래와 같은 파이썬 폴더를 찾으실 수 있을거에요.
파이썬 인증서가 설치되지 않아 발생하는 문제 같습니다.
Install Certificates.command 를 더블클릭하시면 설치하실 수 있을거에요.
