Python/Pyqt5-将选定的下拉选项存储在变量中

Question

我试图根据用户是选择“基本”还是“高级”来运行不同的 if 语句。到目前为止，这是我的代码。我将使用高级/基本选项，因此我可以执行以下操作并将其存储在函数中，然后在需要时调用它。def basicAdvOpt    advBasicOptions = ("Basic", "Advanced")     selection, okPressed = QInputDialog.getItem(self, "Select Basic or Advanced", "", advBasicOptions, 0, False)    if selection[0]:        print('Basic')    if selection[1]:        print('advanced')这是我的原始工作代码。发生的情况是，因为它是一个数组，所以它总是等于 [0] 和 [1]，我试图弄清楚如何存储他们选择的任何值。    def getText(self):        userInput, okPressed = QInputDialog.getText( self,"Input IP-address", "Your IP-address:",QLineEdit.Normal, "")        if okPressed:            self.ipFormatChk(userInput)     #Pass the userInput variable                                             into the ipFormatChk function            if userInput.strip():                self.ipFormatChk(userInput)    def ipFormatChk(self, userInput):  #Checks if the input matches IP                                          format        pattern = r"\b(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\." \                  r"(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\.(25[0-5]|2[0-4][0-9]|[01]?[0-9][0-9]?)\b"        if re.match(pattern, userInput):            additionalText = "This is IP-address"            self.label.setStyleSheet("color: lightgreen; font: 24px;")            advBasicOptions = ("Basic", "Advanced")             selection, okPressed = QInputDialog.getItem(self, "Select Basic or Advanced", "", advBasicOptions, 0, False)            if selection[0]:                print('Basic')            if selection[1]:                print('advanced')#Or just call the function            basicAdvOpt()        else:            additionalText = "This is NOT an IP-address"            self.label.setStyleSheet("color: red; font: 24px;")            advBasic = ("Basic", "Advanced")            advBasic, okPressed = QInputDialog.getItem(self, "Select Basic or Advanced", "", advBasic, 0, False)        self.label.setText("{} <- {}".format(userInput, additionalText))

将结果与数组中的项目进行比较。

advBasicOptions = ("Basic", "Advanced") 

selection, okPressed = QInputDialog.getItem(self, "Select Basic or Advanced", "", advBasicOptions, 0, False)

if selection == advBasicOptions[0]:

    print('Basic')

if selection == advBasicOptions[1]:

    print('advanced')

注意：我可能建议将这两个if语句放在一个封闭if okPressed块中，因为可能会选择Cancel或任何非确定选项。

如果您需要稍后存储它，只需将其保存到 self 上的实例变量中：

advBasicOptions = ("Basic", "Advanced") 

self.selection, okPressed = QInputDialog.getItem(self, "Select Basic or Advanced", "", advBasicOptions, 0, False)

if self.selection == advBasicOptions[0]:

    print('Basic')

if self.selection == advBasicOptions[1]:

    print('advanced')

我希望这回答了你的问题
