I'm trying to write a sudoku program. It works, it draws the board and you can fill in the missing numbers yourself by clicking on the screen, selecting a box (A2 or C7 or G4 etc.) and then entering a number from 1 to 9. I also added a reset button that clears all the numbers you added. But now I also wanted to make it so that it checks whether the sudoku is correct or not. But I can't think of a way to do that. I tried it with the:
#checks for a win
if a2==1 and a5==7 and a8==9 and a9==2 and b3==9 and b4==1 and b5==3 and b6==4 and b7==7 and b8==6 and b9==8 and c1==4 and c4==6 and c5==2 and c6==9 and c7==5 and d1==2 and d2==6 and d4==4 and d6==5 and d7==9 and d9==7 and e2==7 and e3==4 and e7==1 and e8==2 and f1==8 and f3==1 and f4==7 and f6==2 and f8==4 and f9==3 and g3==8 and g4==9 and g5==4 and g6==7 and g9==6 and h1==6 and h2==9 and h3==2 and h4==3 and h5==5 and h6==1 and h7==8 and i1==7 and i2==4 and i5==8 and i8==1 and i9==9:
win.goto(0,0)
win.color("green")
win.write("Correct", font=("Arial", 64, "bold"), align="center")
else:
win.clear()
pass
part, but then I get the error whenever I enter a number. I can still keep playing tho, it just gives me an error everytime I enter a number:

NameError: name 'a5' is not defined
But the variables are defined right? I add them when you enter a number. So what I did was, every empty box has a variable and everytime you enter a number in an empty box, it changes that variable to the number you put in. And then when all the numbers are correct, it tells you so. This is the whole code, sorry if it's too long or a bit messy, I'm working on that:
