내 자신의 이벤트 관련 응용 프로그램에 대해 이와 같은 작업을 수행하지만 자신의 사용 사례를 수행하기에 충분한 코드가 있어야합니다.

import tempfile, csv, os

class UploadPaperTest(TestCase):

    def generate_file(self):
        try:
            myfile = open('test.csv', 'wb')

            wr.writerow(('2','Title2', 'Author2'))
            wr.writerow(('3','Title3', 'Author3'))
        finally:
            myfile.close()

        return myfile
