Я пытаюсь создать систему управления учениками, пока это окно tkinter не отображается после выполнения следующего кода. Может кто-нибудь дать здесь совет? Это publi c исходный код с youtube chanel. 


from tkinter import *

Вы должны инициализировать свой объект Student и передать ему root. Добавьте это в конец вашего кода, чтобы он запустился: 

app=Student(root)
root.mainloop()

Ваш текущий код как есть, включает множество синтаксических ошибок, которые необходимо исправить перед запуском. Следующее должно работать, хотя и с некоторыми визуальными ошибками:
