我正在使用一个内置在 python 3 中的工作脚本来读取一个 excel 文件。使用输入，它会确定我应该使用哪个 VIP（虚拟 IP）子网以及 VIP 应该与哪个 F5 负载均衡器匹配，然后将在负载均衡器上配置所需的 cli 命令作为另一个文件输出。我想知道是否可以使用下面的代码为此添加一个基本的 GUI。基于此，它将在我的桌面上创建一个文件，其中包含我需要配置的命令，这些命令取自 excel 文件和给定的输入。如果excel中的信息为空白，它会提示并询问您。运行的简单工作脚本的编辑示例如下所示：

有人建议我将脚本作为一个函数并将其导入到我所做的 GUI 代码中，并将其命名为 vipTest。接下来，我将它导入到 PySimpleGUI 中，我正在使用这里创建一个简单的表单：
import vipTest
import PySimpleGUI as sg
# Very basic form. Return values as a list
form = sg.FlexForm('VIP Builder') # begin with a blank form
layout = [
[sg.Text('Please enter the information below')],
[sg.Text('What is the change order for this VIP?: ', size=(30, 1)), sg.InputText('change #')],
[sg.Text('Enter the full path of the LBARF form: ', size=(30, 1)), sg.InputText('location path')],
[sg.Text('Which VIP IP did you choose?: ', size=(30, 1)), sg.InputText('ip address of vip')],
[sg.Submit(), sg.Cancel()]
]
lbarf_file, folder = vipTest.createfolder(directory)
button, values = form.Layout(layout).Read()
我无法从结果的 GUI 中获取输出。当我在 PyCharm 中运行这个程序时，GUI 没有打开，脚本在控制台中运行。即使我可以让 GUI 使用特定示例，我担心每次 excel 文件中的信息为空白时，我可能需要让 GUI 添加一个文本字段。我想最终想从 gui 显示配置命令，但没有按原样使用它。非常感谢您对此的任何帮助。谢谢你。
