[Django] 엑셀 읽고 딕셔너리(Dictionary) 형태로 Django 페이지에 불러오기

http://portfolio.wonpaper.net 2022. 9. 2. 12:39

위에서 42라인 grade_calculate_dic.keys() 은 dict_keys 객체를 반환해 준다.  (파이썬 3.0부터)

(파이썬 2.0에서는 리스트가 반환되었다.)

 

이를 다시 리스트로 바꾸려면

grade_list = list(grade_calculate_dic.keys()) 

 

66라인부터는 

grade_calculate_dic 와  email_domain_dic 라는 두개의 딕셔너리를 세션으로 굽고 

result 함수로 이동하여 결과페이지에 불러와본다.
