QListWidget、QListWidgetItem、QAbstractItemView和QIcon導入可以被刪除。該變量也pixmap可以被刪除，因為它“從未使用過”。
要修復有關星號導入的警告，請顯式定義導入，如下所示：
from PyQt5.QtGui import QPainter, QPalette, QFont
from PyQt5.QtWidgets import QGraphicsScene, QFrame, QGraphicsView, QGraphicsPixmapItem, QDialog, QFormLayout, QMessageBox
from PyQt5 import QtCore
然后刪除明星進口。
