我的目标是打印一张如下所示的 map :
- 9 8 7 6 5 4 3 2 1
- 8 7 6 5 4 3 2 1 9
- 7 6 5 4 3 2 1 9 8
- 6 5 4 3 2 1 9 8 7
- 5 4 3 2 1 9 8 7 6
- 4 3 2 1 9 8 7 6 5
- 3 2 1 9 8 7 6 5 4
- 2 1 9 8 7 6 5 4 3
- 1 9 8 7 6 5 4 3 2
但我不明白为什么它只是打印:
- 9 8 8 8 8 8 8 8 8
- 8 9 9 9 9 9 9 9 9
- 8 9 9 9 9 9 9 9 9
- 8 9 9 9 9 9 9 9 9
- 8 9 9 9 9 9 9 9 9
- 8 9 9 9 9 9 9 9 9
- 8 9 9 9 9 9 9 9 9
- 8 9 9 9 9 9 9 9 9
- 8 9 9 9 9 9 9 9 9
你知道为什么我无法实现我的目标吗?
最佳答案
在搜索函数中使用 else 和 for 循环。这样,仅当没有迭代返回中断时才返回 1。您甚至可以在 for 循环后简单地返回 1。
#it will determine whether there is a same a in row or not
def search_row(sudoku_map_search, a, row):
for i in range(9):
if sudoku_map_search[row][i] == a:
return 0;
else:
return 1;
或者在 for 循环后返回 1。仅当没有迭代成功时才会返回 1。
#it will determine whether there is a same a in row or not
def search_row(sudoku_map_search, a, row):
for i in range(9):
if sudoku_map_search[row][i] == a:
return 0;
return 1;
