我在返回False和def checkit函数中的追加号时遇到问题。我不确定我是否错误地编写了checkrow函数。当给出正确解决的数独谜题时,它能够返回true,但是当我们要调用不正确的数独谜题时,它将返回False,并提供有问题的行。目前,它只返回有问题的行,也就是说拼图失败的位置,但不包括错误。关于如何制作它以使它返回两者的任何想法?
import sys
from scanner import *
def createList(size):
if size == 0: return []
else:
return [0] + createList(size -1)
def printGrid(gridlist):
for row in gridlist:
print (str(row)+"\n")
def rows(g):
return len(g)
def cols(g):
return len(g[0])
def printMatrix(g):
for i in range(0,rows(g),1):
for j in range(0,cols(g),1):
print(g[i][j],end=' ')
print('')
print('')
def readinput(filename,grid):
s = Scanner(filename)
r = s.readtoken()
while r != "":
r = int(r)
c = s.readint()
v = s.readint()
grid[r][c]=v
r = s.readtoken()
def checkRows(g):
for rows in g:
numbersInRow = []
for number in rows:
if number != 0 and number in numbersInRow:
return g.index(rows)
else:
numbersInRow.append(number)
return True
def checkIt(g):
checkRows(g)
rowSuccess = checkRows(g)
print(rowSuccess)
def main():
grid = createList(9)
for i in range(9):
grid[i] = createList(9)
readinput(sys.argv[1],grid)
printMatrix(grid)
checkIt(grid)
main()

您可以退回两者:
def checkRows(g):
for rows in g:
numbersInRow = []
for number in rows:
if number != 0 and number in numbersInRow:
return g.index(rows), False
else:
numbersInRow.append(number)
阅读它:
problematic_row, result = checkRows(g)
答案 1 :(得分:0)
return False, g.index(rows)
将返回两个值作为元组。
