I want to print the permutations of every line(n = 9, k= 9), so that I end up with 1814400 total lines (362880 x 5).Here is my code
import itertools
with open('12round.txt') as file:
> for line in file:
> perms = itertools.permutations(line, 9)
> for i in perms:
> print(' '.join(i))`
however it prints like letters and its just weird. Please help! I've been trying to find a solution and I'm getting a headache not finding anything thanks in advance.
this is as far as my script writing goes.

如果我正确理解您的问题，您读取了一行文本，需要获取该行的单词，然后进行排列组合操作。我猜您的问题可能在于未删除空格并提取单词，然后再运行itertools.permutations。以下是一个示例代码（我根据您的示例取了n=9，k=9）：
import itertools
with open('file.txt') as file:
for line in file:
line = line.strip()
perms = itertools.permutations(line.split(), 9)
for i in range(9):
for perm in perms:
print(' '.join(perm))
希望这能帮助您解决问题。
英文:
if I understood your problem correctly, you read a line, you need to get the words of this line, then you do your permutations accordingly,
I guess your problem is that you are not removing the white spaces and taking the words then running itertools.permutations.
Here is a sample code: (I took the n=9, k=9 according to your example)
import itertools
with open('file.txt') as file:
for line in file:
line = line.strip()
perms = itertools.permutations(line.split(), 9)
for i in range(9):
for perm in perms:
print(' '.join(perm))
