[Python] How can I call two variables from a class of another script (tkinter) so they are...

I have two scripts, one is the main.py and the other has a class that has a TKinter IU. From the TKinter, it should get some variables, and those variables should be the input for the main.py.

How can I make this possible?

I've tried to do this, but it's only my second day with tkinter libraries and don't know much about classes.

This is the supertrend02_tk.py (tkinter)

import config
from binance.client import Client
from binance.enums import *
from tkinter import *
from tkcalendar import Calendar
import tkinter as tk

client = Client(config.API_KEY, config.API_SECRET, tld='com')

exchange_info = client.get_exchange_info()


class Window(Frame):
def __init__(self, master=None):
Frame.__init__(self, master)
self.master = master
self.pack() # Window is packed in its master.

exitButton = Button(self, text="1st Run this", command=self.clickrunButton)
exitButton.pack()

def clickrunButton(self):
self.run() # Now this work



def run(self):
def get_info():
data=[]
for s in exchange_info['symbols']:
print(s['symbol'])
data.append(s['symbol'])
info_recibida = data

return info_recibida

OPTIONS = get_info()

def on_change_selection(value):
print(' value:', value)
print('selected:', selected.get())

master = Tk(className='SuperTrend Backtesting Bot')

selected = tk.StringVar(master)
selected.set(OPTIONS[0])

w = OptionMenu(master, selected, *OPTIONS, command=on_change_selection)

# set window size
master.geometry("500x500")

#master.mainloop()
####################################################
# Add Calendar
cal = Calendar(master, selectmode = 'day',
year = 2022, month = 11,
day = 13)

cal.pack(pady = 20)

def grad_date():
date.config(text = "Selected Date is: " + cal.get_date())

# Add Button and Label
Button(root, text = "Get Date",
command = grad_date).pack(pady = 20)

date = Label(root, text = "")

dia_inicial = cal.get_date()

date.pack(pady = 20)

w.pack()



root = Tk()
app = Window(root)

# set window title
root.wm_title("Supertrend")

# show window
root.mainloop()


And the variables that I should use in the main.py are:

from binance.client import Client

from tkinter import *
from tkcalendar import Calendar
import tkinter as tk
client = Client(config.API_KEY, config.API_SECRET, tld='com')

exchange_info = client.get_exchange_info()
import supertrend02_tk
from supertrend02_tk import dia_inicial, selected

plt.style.use('fivethirtyeight')
plt.rcParams['figure.figsize'] = (20,10)

print("cara_bobo")
symbolo=selected
print(symbolo)
idate=dia_inicial
print(idate)
