I am trying to write my first app using Tkinter. I can't understand at all how it is possible to pass the data on variables in the 2D array (entered by user) from one class to another. Tried to change something, but nothing turned out. I will be very grateful for any help or advice.
from Tkinter import *
date_index = [2017, 2018, 2019, 2020, 2021]
product_name = ['product 1', 'product 2', 'product 3', 'product 4', 'product 5']
class main:
def __init__(self, master):
self.master = master
self.master.title('revenue calc')
Button(self.master, text = 'quantity', command=self.q_button).pack()
Button(self.master, text = 'prices', command=self.p_button).pack()
self.master.mainloop()

q_child(self.master)

p_child(self.master)

self.slave = Toplevel(master)
self.slave.title('quantity')

self.button_frame.grid(row=2, column=1)
for i in range(len(product_name)):

self.testlabel.grid(row=i, column=0)
