当我按下空格键时，如何从一个.py调用代码以在另一个.py中运行。两个.py都在同一个文件中。
我有一个叫做solve的代码，我想在运行数独代码时按空格来调用它。这是solver.py，它们都在一个名为Sudoku solver的文件夹中。如果这很简单，我道歉；我不太了解pygame。
def solve(bo):
find = find_empty(bo)
if not find:
return True
else:
row, col = find
for i in range(1,10):
if valid(bo, i, (row, col)):
bo[row][col] = i
if solve(bo):
return True
bo[row][col] = 0
def valid(bo, num, pos):
# check row
for i in range(len(bo[0])):
if bo[pos[0]][i] == num and pos[1] !=i:
return False
# check column
for i in range(len(bo)):
if bo[i][pos[1]] == num and pos[0] !=i:
return False
# check box
box_x = pos[1] // 3
box_y = pos[0] // 3
for i in range(box_y * 3, box_y * 3):
for j in range(box_x * 3, box_x * 3):
if bo[i][j] == num and(i, j) != pos:
return False
return True
def print_board(bo):
for i in range(len(bo)):
if i % 3 == 0 and i !=0:
print("- - - - - - - - - - - - -")
for j in range(len(bo[0])):
if j % 3 == 0 and j != 0:
print(" | ", end="")
if j == 8:
print(bo[i][j])
else:
print(str(bo[i][j]) + " ", end="")
def find_empty(bo):
for i in range (len(bo)):
for j in range(len(bo[0])):
if bo[i][j] == 0:
return (i, j) #(row,column)
return None
这是数独

在我看来，您似乎已经处理了按下空格的事件，您将从另一个文件调用solve。我认为你做得对。然而，我认为您错误地完成了solver.solve((的输入参数。在GUI.py中查看代码时，似乎没有名为bo的变量。通过查看它，我假设正确的输入参数应该是board。
你能试着把197号线从：改一下吗
solver.solve(bo)
至：
solver.solve(board)
只是一个额外的评论：
由于您在第3行中使用了from solver import solve, valid，因此不需要在第197行中使用solver.solve(bo)。相反，您可以简单地使用solve(bo)。不过，这不是问题，您使用的方式也与您在第5行使用import solver一样有效。
