Я использую рабочий скрипт, встроенный в python 3, который читает файл Excel. Используя данные, он определяет, какой VIP (Виртуальный IP) su bnet I следует использовать и с каким балансировщиком нагрузки F5 должен сопоставляться VIP, а затем выдает команды cli, необходимые для настройки на балансировщике нагрузки, в виде другого файла. Я хочу знать, возможно ли добавить basi c GUI к этому, используя код, который я имею ниже. Исходя из этого, он создаст файл на моем рабочем столе с командами, которые мне нужно настроить, взятыми из файла Excel и введенными данными. Если информация в Excel пуста, она предложит вам запрос. Отредактированный пример простого рабочего скрипта, который выполняется, показан ниже:

Мне было предложено поместить скрипт как функцию и импортировать его в код для GUI, который я сделал и назвал это vipTest. Затем я импортировал его в PySimple GUI, который я использую для создания простой формы:
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()
У меня проблемы с получением результата из GUI результатов. Когда я запускаю эту программу в PyCharm, GUI не открывается и скрипт запускается в консоли. Даже если я смогу заставить GUI работать с конкретным примером c, я обеспокоен тем, что мне может потребоваться добавить текстовое поле GUI каждый раз, когда информация в файле excel пуста. В конечном счете, я хотел бы отобразить команды конфигурации из gui, но я никуда не попадаю, как есть. Любая помощь в этом очень ценится. Спасибо.
