SyntaxError: unexpected character after line continuation character

may be is "\n" wrong?
if don't use "\n",it's right.
BUT I need "\n"

Please avoid using links, post code here in bbcode tags instead (which I have done here)

not hommework,pleas.

'\n' is a carraige return string. Without quotes the backslash is a line continuation character.

The code is ugly. Almost unreadable. There must be a better way to do what you are trying ro do.

Please, don't use ALL CAPS. That is considered shouting.

This is my best guess at what you are trying to accomplish. I left out the file write, but it would be very similar to the print.

import random
import itertools

def add_unique(xlist, ylists):
    """Append xlist to ylists only if xlist[i] is not in ylist[i] for
    every value if i.
    """
    for y, x in zip(ylists, xlist):
        if x in y:
            break; # Not unique
    else:
        # Is unique.  Only get here if didn't break out of for loop.
        for ylist, x in zip(ylists, xlist):
            ylist.append(x)

xlist_values = [str(n+1) for n in range(9)]
ylists = [[] for _ in range(9)]
times = 0
while len(ylists[0]) < 9:
    xlist = random.sample(xlist_values, k=9)
    add_unique(xlist, ylists)
    times += 1

print(f"FINISH {times} TIMES")
for index in range(9):
    print(', '.join([ylist[index] for ylist in ylists]))

I am not sure what the code is supposed to do. Since it makes a 9x9 matrix of numbers in the range 1..9 it looks suspiciously like a Sudoku maker. If so it does not make valid Sudoku puzzles. Values are unique for each row and each column, but not for each 3x3 box.
