算了，评论里缩进有问题，私我吧，

import itertools
nums = [i for i in range(9)]
deng=[(1,1),(2,5),(3,3),(4,7),(5,9),(6,6),(7,8),(8,2),(9,4)]
def bianli(i,j):
i_=i
temp=i
j_=j
while(i_<8):
if matrix[i_+1][j]==1:
break
else:
matrix[i_+1][j]=1
i_+=1
while (i > 0):
if matrix[i -1][j] == 1:
break
else:
matrix[i -1][j] = 1
i -= 1
while (j_ < 8):
if matrix[temp][j_+1] == 1:
break
else:
matrix[temp][j_+1] = 1
j_ += 1
while (j > 0):
if matrix[temp][j-1] == 1:
break
else:
matrix[temp][j-1] = 1
j -= 1
def isfull():
for i in range(len(matrix)):
for j in range(len(matrix[0])):
if matrix[i][j]==0:
return False
return True
for num in itertools.permutations(nums):
matrix = [[0 for i in range(9)] for i in range(9)]
for i in num:
matrix[deng[i][0]-1][deng[i][1]-1]=1
bianli(deng[i][0]-1,deng[i][1]-1)
if isfull():
for i in num:
print(i+1,end=",")
break

注意缩进，四个空格为一组
