Отключить кнопку отправки, пока все поля не будут заполнены в Python Tkinter

Question

В настоящее время я работаю над проектом, и когда моя программа запускается, ей нужно получить имена двух игроков, прежде чем начать, так же, как моя программа в данный момент, можно нажать «отправить» без ввода имен, как это сделать?Я предотвращаю это?

Большое спасибо Jayode18

submit_button.grid(row = 7, column = 4, columnspan = 2)

mainWindow.grid(row = 5, column = 0)

window.mainloop()

Вся помощь будет потрясающей, спасибо еще раз!: D

Спасибо всем за помощь.Мне удалось найти рабочее решение!

Вы можете проверить введенные тексты, например

if entry1.get() != "" And entry2.get() != "":
    # entries are not empty, do something
