将 combobox 上的选定项目连接到 pyqt5 中的一行

Question

当在 combobox 中按下项目时，我想调用 csv 并检索在 combobox 中单击项目时匹配的行

class Ui_Dialog(object):
 def setupUi(self, Dialog):
    sales=pd.read_csv ("C:/Users/DELL/Desktop/Info/Topholdings/csv/Master_table.csv")
    sales_article = sales ["Company"] .dropna()
    sales_list = sales_article.values.tolist()
    self.Fundwise = QtWidgets.QComboBox(Dialog)
    self.Fundwise.setGeometry(QtCore.QRect(308, 141, 141, 61))
    self.Fundwise.setObjectName("sales_list")
    self.Fundwise.addItems(arr_list)

In the above code I call the csv file and select the first column as list which is displayed in the combobox,but when the user clicks one of the items in the combobox how to call the selected strings row

Answer 1

def setupUi(self, Dialog):
     #....
     self.Fundwise.activated.connect(self._set_fundwise)

def _set_fundwise(self):
    _data = self.Fundwise.currentData()
    if _data:
       #call selected strings
