python+pyqt 5 KFC 주문 수납 시스템 구현

본 논문 의 사례 는 python 이 KFC 주문 수납 시스템 을 실현 하 는 구체 적 인 코드 를 공유 하여 여러분 께 참고 하 시기 바 랍 니 다.구체 적 인 내용 은 다음 과 같 습 니 다.
이 kfc 수납 시스템 에서 제 가 실현 한 다음 과 같은 기능:
1.정상 적 인 음식 결제 와 거스름돈.
2.기본 세트 결제 와 거스름돈.
3.혜택 을 이용 해 학 전갈 이 방 을 삐다 낙타 이각
4.일정 시간 동안 매장 내 이벤트 참여 가능
5.작은 표 인쇄 를 모 의 하 는 기능(파일 에 쓰기).
프로젝트 파일:

KFC.py 파일 은 각 기능,kfctip.txt 파일 을 실현 하여 작은 표를 인쇄 하고 picture 파일 에 인터페이스 에 필요 한 그림 을 저장 하 며 다른 네 개의 파일 은 각 인터페이스 레이아웃 입 니 다.
주 인터페이스:

정상 메뉴 주문 창:

정식 주문 창:

이벤트 세트 주문 창:

두 번 째 이벤트 세트 를 클릭 하면:

주문 가입 클릭 하여 반환 후 메 인 인터페이스 에서 주문 정 보 를 생 성 합 니 다:

클릭 하여 결제:



작은 표를 파일 로 인쇄 하기:

다음은 코드 구현:
인터페이스 레이아웃 모두 pyqt 5 사용
