from PyQt5.QtCore import *
from PyQt5.QtWidgets import *
listItem = ['a','b','c','d','e']
if listItem is not None and len(listItem) > 0:
 self.listWidget = QListWidget(self)
 for item in listItem:
 self.listWidget.addItem(item)
 if multiselected:
 self.listWidget.setSelectionMode(QAbstractItemView.ExtendedSelection)#按住CTRL可多选
 # self.listWidget.itemClicked.connect(self.listItemClick)
 # self.listWidget.itemDoubleClicked.connect(self.listItemDoubleClick)
text_list = self.listWidget.selectedItems()
text = [i.text() for i in list(text_list)] 
text = '_',join(text) # text即多选项并以_隔开
