我对python还是个新手。
我试图使一个脚本,将阅读数独解决方案和威慑,如果他们是正确的或不。
我需要的东西
1]提示用户输入一个包含数独数字的文件/文件路径。它是一个9行9列的.txt文件。只包含数字。
2]有某种错误处理。
3]然后,如果数独有效,我应该创建一个新的文本文件,使用与原始输入文件相同的格式,并带有前缀“Correct_”
我还没有完全完成程序,但我得到这个错误时,我把一个虚假的路径或文件名。
Hello to Sudoku valitator,
Please type in the path to your file and press 'Enter': example.txt #This is a non existing file, to test the Error Exception
'Traceback (most recent call last):
File "C:/Users/FEDROS/Desktop/bs.py", line 9, in <module>
sudoku = open(prompt, 'r').readlines()
FileNotFoundError: [Errno 2] No such file or directory: 'example.txt'
这是我的剧本
while True:
try:
prompt = input("\n Hello to Sudoku valitator,"
"\n \n Please type in the path to your file and press 'Enter': ")
break
except (FileNotFoundError, IOError):
print("Wrong file or file path")
sudoku = open(prompt, 'r').readlines()
def check(game):
n = len(game)
if n < (1):
return False
for i in range(0, n):
horizontal = []
vertical = []
for k in range(0, n):
if game[k][i] in vertical:
return ("File checked for errors. Your options are wrong!")
vertical.append(game[k][i])
if game[i][k] in horizontal:
return ("File checked for errors. Your options are wrong!")
horizontal.append(game[i][k])
return ("File checked for errors. Your options are correct!")
print (check(sudoku))
谢谢,任何建议或帮助将不胜感激。

try
块应该在open附近。而不是在prompt附近。pgx2nnw82#
您可以尝试在open()函数之前添加以下代码:
