英文:
How do I go into all text files in a directory and delete everything in them after the second space?
问题
I have a directory like this:
每个文本文件都包含以下信息：
106 114 24 25 1 0
705 79 19 21 1 0
661 361 30 37 1 0
212 332 30 37 1 0
704 236 20 25 1 0
620 404 30 37 1 0
615 248 20 25 1 0
641 165 20 25 1 0
676 47 19 21 1 0
我正在尝试编写一个脚本（在Windows 11上），该脚本进入该目录，访问每个文本文件，并删除第二个空格之后的所有内容。
基本上，我希望新的文本文件如下所示：
106 114
705 79
661 361
212 332
704 236
620 404
615 248
641 165
676 47
该脚本也可以使用Python编写。

Each text file has this information:
106 114 24 25 1 0705 79 19 21 1 0661 361 30 37 1 0212 332 30 37 1 0704 236 20 25 1 0620 404 30 37 1 0615 248 20 25 1 0641 165 20 25 1 0676 47 19 21 1 0
I am trying to write a script (windows 11) that goes into this directory, accesses each text file and deletes everything after the second space.
Basically, I want the new text files to be like this:
106 114705 79661 361212 332704 236620 404615 248641 165676 47
The script can be in python as well

import os
directory = '/path/to/directory'
for filename in os.listdir(directory):
if filename.endswith('.txt'):
with open(os.path.join(directory, filename), 'r+') as file:
lines = file.readlines()
file.seek(0)
for line in lines:
words = line.split()
new_line = ' '.join(words[:2]) + '\n'
file.write(new_line)
file.truncate()
英文:
import osdirectory = '/path/to/directory'for filename in os.listdir(directory):if filename.endswith('.txt'):with open(os.path.join(directory, filename), 'r+') as file:lines = file.readlines()file.seek(0)for line in lines:words = line.split()new_line = ' '.join(words[:2]) + '\n'file.write(new_line)file.truncate()
Replace /path/to/directory with the path to your directory

这应该可以运行：
import osDIR = '/path';for listed_file in os.listdir(DIR):if listed_file.endswith(".txt"):with open(listed_file, 'r') as file:final_lines = []for line in file.readlines():new_line = " ".join(line.split()[:2]) + "\n"final_lines.append(new_line)file = open(listed_file, 'w')file.writelines(final_lines)
它将遍历DIR中的每个文件，检查它是否是一个txt文件，然后获取它的行并使用新的分割行重写它。
英文:
This should work:
import osDIR = '/path'for listed_file in os.listdir(DIR):if listed_file.endswith(".txt"):with open(listed_file, 'r') as file:final_lines = []for line in file.readlines():new_line = " ".join(line.split()[:2]) + "\n"final_lines.append(new_line)file = open(listed_file, 'w')file.writelines(final_lines)
it will run through each and every file in DIR, check if it is a txt file and then get its lines and rewrite it with the new split lines.
