window.mainloop()
def back_login():
window.destroy()
root.deiconify()
def back_login2():
window.destroy()
instance_kelas = TicketSystem()
An error appears, namely that Tkinter has no attribute ticket_price the problem is when i try to run the first code it will run fine, but when i try to connect the two codes it gives an error
Please help me to solve the error
You've correctly passed the tk.Tk object to the class TicketSystem. Therefore, the methods of tk.Tk can be called. However, you forgot to pass your own variable in the __init__ method, which is not a Tkinter function or attribute.
Therefore, you get this error:
Tkinter has no attribute ticket_price
By default, when you say self, Python looks for self within the class you already have. If it does not find the attribute, it would go up to the class you've inherited from (if any), and if not found there, it will return an AttributeError.
