PYQT5 for循环动态创建变量名，对应同一个槽函数，响应输出对应的按钮名称

class SelectMapWindow(QMainWindow):
    def __init__(self):
        QMainWindow.__init__(self)

        self.setCentralWidget(w)

        self.topFiller = QWidget()
        self.topFiller.setMinimumSize(250, len(os.listdir("source/map"))*50+30)
        self.mainGroupLayOut()

        scroll = QScrollArea()
        scroll.setWidget(self.topFiller)

        vbox = QVBoxLayout()
        vbox.addWidget(scroll)
        w.setLayout(vbox)
        self.resize(300, 500)


    def mainGroupLayOut(self):
        number = 0
        self.varList = os.listdir("source/map")

        for filename in os.listdir("source/map"):
            self.varList[number] = QPushButton(self.topFiller)
            self.varList[number].setText(str(filename))

            self.varList[number].clicked.connect(lambda: self.MapButton_clicked(self.sender().text()))#########连接槽函数并把自身变量名传递过去

            self.varList[number].move(10,(number+1)*50)
            number += 1



    def MapButton_clicked(self,number):
        print(number)

    app = QApplication(sys.argv)
    window = SelectMapWindow()
    window.show()
    sys.exit(app.exec_())
