강의에서 배운 Tips

  • urllib3보다 requests가 더 사용하기 편하다.
  • BeautifulSoup를 이용하여 HTML문서에서 원하는 데이터에 간편하게 접근할 수 있다.
  • list[-1]은 list의 마지막 요소를 가리킨다. list[0:-1] 또는 list[:-1]은 list의 첫번째부터 마지막 전까지를 나타낸다.(마지막 요소를 제외한 모든 요소)
    []안의 -1은 'len(list)-1'로 추정된다.(개인적인 생각)

기타

  • package 확인하기
$ pip show 'package-name'
  • package 설치하기
$ pip install 'package-name'
  • 다른 환경에서 작업할 일이 많을 경우 requirements.txt로 패키지를 관리하면 편리하다.
    (이름을 꼭 저걸로 할 필요는 없으나 대부분 저 이름으로 관리)
#파일 생성
$ pip freeze > requirements.txt

#패키지 설치
$ pip install -r requirements.txt
