Python sudoku programming
- by trevor
I need your help on this. I have this program and I must finish it. It's missing 3 parts.
Here is the program I'm working with:
import copy
def display(A):
if A:
for i in range(9):
for j in range(9):
if type(A[i][j]) == type([]): print A[i][j][0],
else: print A[i][j],
print
print
else: print A
def has_conflict(A):
for i in range(9):
for j in range(9):
for (x,y) in get_neighbors(i,j):
if len(A[i][j])==1 and A[i][j]==A[x][y]: return True
return False
# HERE ARE THE PARTS THAT REQUIRE HELP!!!!
def get_neighbors(x,y):
return []
def update(A, i, j, value):
return []
def solve(A):
return []
# ENDS PARTS THAT REQUIRE HELP!!!!
A = []
infile = open('puzzle1.txt', 'r')
for i in range(9):
A += [[]]
for j in range(9):
num = int(infile.read(2))
if num: A[i] += [[num]]
else: A[i] += [[1,2,3,4,5,6,7,8,9]]
for i in range(9):
for j in range(9):
if len(A[i][j])==1: A = update(A, i,j, A[i][j][0])
if A==[]: break
if A==[]: break
if A<>[]: A = solve(A)
display(A)
I need to solve the stuff formerly in bold letters, now explicitly marked in the code, specifically
- get_neighbors():
- update():
- solve():
Thank you for your time and help.
