데이터 저장과 취급
여러분 데이터에 관한 질문
우리는 웹앱의 기능을 멋지게 완성했습니다. 하지만
6
장을 시작하면서 던졌던 다음
질문에 모두 답하진 못했습니다. 얼마나 많은 요청에 응답했는가? 가장 많이 사용된
철자 목록은 무엇인가? 어떤
IP
주소에서 요청이 들어왔는가? 가장 많이 사용된
브라우저의 종류는 무엇인가?
마지막 두 개의 질문은 /
viewlog
URL
에 표시되는 정보로 어느 정도 답변이 될
수 있습니다. 요청이 어디서 왔는지는
Remote
_
addr
열에 표시되어 있고 사용된
브라우저 종류는
User
_
agent
열에 표시되어 있으니까요. 하지만 우리 사이트를
사용한 사용자가 주로 사용한 브라우저의 종류를 알아내는 것은 쉽지 않습니다.
단순하게 출력된 로깅 데이터로는 알 수 없죠. 추가 연산을 수행해야 합니다.
첫 번째 두 질문도 답변하기 쉽지 않습니다. 이 두 질문을 답변하려면 마찬가지로 추가
연산이 필요합니다.
그러니까
추가로 연산하는 코드를
구현해야 하는군요?
꼭 필요할 때만 코드를 구현하세요.
우리가 가진 기술이 파이썬뿐이라면 남은 질문에 답변하기 위해
많은 코드를 구현해야 합니다. 어쨌든 파이썬 코드를 구현하는
것은 재미있을 뿐 아니라 파이썬은 데이터 취급에 필요한
기능도 잘 제공합니다. 하지만 남은 질문
