I am triying to write sudoku solver. This is really complicated code for me. I want to update board while python calculating other things. However, code could not do that. Should I try threading or is there easy way to do that?
CURRENT SITUATION: end of the calculation.
I am inserting values. Then, I click solve. I am changing text of label (via code), but label waits untill end of calculations and suddenly applies labels’ changes.
related codes in "def solve() > def set_text(), def check()"
my complete code:
import tkinter
from copy import deepcopy
import time
import threading
window = tkinter.Tk()
window.title("Sudoku Solver")
window.config(padx=30, pady=30)
zerolist = [] # adı posibles olacak
entrylist = []
exactvals = []
labellist = []
def create000():
global zerolist
global exactvals
for i in range(9):
zerolistemp = []
exectemp = []
for j in range(9):
zerolistemp.append([])
exectemp.append(0)
zerolist.append(deepcopy(zerolistemp))
exactvals.append(deepcopy(exectemp))
zerolistemp.clear()
exectemp.clear()
return zerolist
# def solve():
# def check(i,j):
# global zerolist
# for i in range(9):
# for j in range(9):
# for element in zerolist[i][j]:
# if j == 9:
def solve():
def set_text(x, y, text):
time.sleep(1)
global labellist
if str(text) == "":
labellist[x][y].config(text=str(text), background="gray")
elif len(zerolist[x][y]) == 1:
labellist[x][y].config(text=str(text), background="lightgreen")
elif text != 0:
labellist[x][y].config(text=str(text), background="red")
return
def check(i, j):
print("check")
global zerolist
global exactvals
columnpart = int(i / 3)
rowpart = int(j / 3)
for element in zerolist[i][j]:
print(element)
set_text(i, j, element)
time.sleep(0.5)
# elementi lable a yaz kırmızı yap
# 3x3
for m in range(3):
for n in range(3):
if element == exactvals[columnpart + m][rowpart + n]:
zerolist[i][j].pop(element)
set_text(i, j, "")
return False
if element in exactvals[i] or element in [row[j] for row in exactvals]:
zerolist[i][j].pop(element)
set_text(i, j, "")
return False
exactvals[i][j] = element
if j != 8:
if check(i, j + 1) == False:
exactvals[i][j] = 0
zerolist[i][j].pop(element)
set_text(i, j, "")
return False
elif i != 8:
if check(i + 1, 0) == False:
exactvals[i][j] = 0
zerolist[i][j].pop(element)
set_text(i, j, "")
return False
else:
# write yeşil
set_text(i, j, element)
return True
check(0, 0)
return exactvals
def collect_data(): # collec ederken zaten var i j kullanıp uctan ekleyebiliriz
global zerolist
global exactvals
global labellist
for i in range(9):
for j in range(9): # yatay liste değiştiriyor
if len(entrylist[i][j].get()) != 0:
value = [int(entrylist[i][j].get())]
exc = int(entrylist[i][j].get())
labellist[i][j].config(text=exc, background="lightgreen")
else:
value = [x + 1 for x in range(9)]
exc = 0
zerolist[i][j] = value
exactvals[i][j] = exc
solve()
return zerolist
for row in range(9):
tempentry = []
for column in range(9):
a = tkinter.Entry(width=3)
a.grid(column=column, row=row)
tempentry.append(a)
entrylist.append(tempentry)
emptylabel = tkinter.Label(width=3)
emptylabel.grid(column=9,row=0,rowspan=9)
for row in range(9):
templabel = []
for column in range(10, 19):
a = tkinter.Label(width=3,borderwidth=2, relief="groove")
a.grid(column=column, row=row)
templabel.append(a)
labellist.append(templabel)
but_solve = tkinter.Button(command=collect_data, text="SOLVE", width=9, pady=5)
but_solve.grid(columnspan=3, row=9, column=3)
create000()
window.mainloop()
I want to see changes in real-time while python calculating other things.
I tried threading like this: [![threading code][1]][1]

>Solution :
Hello you can try to add a window.update() in your set_text function. This should update the tkinter window and show you the labels in realtime.
