Hi!
This i s my first post, i got a problem with code what i make. Problem is that pickle dont get ver. when is changed in tkinter. I use many steps to check when ver. is 0 or 1. Maybe something wrong with declaration of var?
here is repls: https://repl.it/repls/CadetblueMysteriousTechnician
import tkinter as tk
import pickle
s1=s2=s3=0
class Cbuttons:
def __init__(self):
self.root = tk.Tk()
self.root.title("Checklist")
self.CheckVar1 = tk.IntVar()
self.CheckVar2 = tk.IntVar()
self.CheckVar3 = tk.IntVar()
self.main()
def save(self):
print('To save:',s1,s2,s3)
with open('asy.txt', 'wb') as f:
pickle.dump([s1,s2,s3], f)
print('Saved!',s1,s2,s3)
def loading(self):
with open('asy.txt', 'rb') as f:
s1,s2,s3= pickle.load(f)
print(s1,s2,s3)
def confirm(self):
if self.CheckVar1.get():
s1=1
pickle.dump(s1, open("asy.txt", "wb"))
else:
s1=0
if self.CheckVar2.get():
s2=1
else:
s2=0
if self.CheckVar3.get():
s3=1
else:
s3=0
print('chek status:',s1,s2,s3)
self.save()
def main(self):
C1 = tk.Checkbutton(self.root, text="Option A", variable=self.CheckVar1, anchor='w', onvalue=1,
offvalue=0, height=1, width=40, command=self.confirm)
C2 = tk.Checkbutton(self.root, text="Option B", variable=self.CheckVar2, anchor='w', onvalue=1,
offvalue=0, height=1, width=40, command=self.confirm)
C3 = tk.Checkbutton(self.root, text="Option C", variable=self.CheckVar3, anchor='w', onvalue=1,
offvalue=0, height=1, width=40, command=self.confirm)
C1.pack()
C2.pack()
C3.pack()
b = tk.Button(self.root, text="OK", command=self.loading)
b.pack()
self.root.mainloop()
if __name__ == '__main__':
Cbuttons()

The problem comes from using global variables s1, s2, s2. Try this version
import os
import tkinter as tk
import pickle
s = [0, 0, 0]
class Cbuttons:
def __init__(self):
self.root = tk.Tk()
self.root.title("Checklist")
self.checkvars = [tk.IntVar() for i in range(3)]
self.main()
def save(self):
print('To save:', *s)
with open('asy.txt', 'wb') as f:
pickle.dump(s, f)
print('Saved:', *s)
def loading(self):
if not os.path.exists('asy.txt'):
with open('asy.txt', 'wb') as f:
pickle.dump(s, f)
with open('asy.txt', 'rb') as f:
s[:] = pickle.load(f)
for v, n in zip(self.checkvars, s):
v.set(n)
print('Loaded:', *s)
def confirm(self):
s[:] = [1 if v.get() else 0 for v in self.checkvars]
print('chek status:', *s)
self.save()
def main(self):
C1 = tk.Checkbutton(
self.root, text="Option A",
variable=self.checkvars[0], anchor='w', onvalue=1,
offvalue=0, height=1, width=40, command=self.confirm)
C2 = tk.Checkbutton(
self.root, text="Option B",
variable=self.checkvars[1], anchor='w', onvalue=1,
offvalue=0, height=1, width=40, command=self.confirm)
C3 = tk.Checkbutton(
self.root, text="Option C",
variable=self.checkvars[2], anchor='w', onvalue=1,
offvalue=0, height=1, width=40, command=self.confirm)
C1.pack()
C2.pack()
C3.pack()
b = tk.Button(self.root, text="OK", command=self.loading)
b.pack()
self.root.mainloop()

I understood, ty  for your help. When we need another group (checkbox) name: "d" we add something like that or something else?
In my program that code is for setup window. That kind will take all choices what user make. I thinking, that file 'asy.txt' keeps all variables simply numbers and choices. So i try make two groups:
1st- variables only numbers exp.: (ax,ay,aR,aG,aB -1st group, bx,by,bR,bG,bB -2nd group)<- that is for main program (he will load that)
2nd - choises only predifine via user like that code from setup window ( s1,s2,s3 - 1st group, d1,d2 - 2nd group)
So my question is ho wwe make groups in file in array or jsut like you show me?
here i add second group its correct?:
