Python：遍历/mydir下的所有目录，删除所有名称中带有“(1)”的文件

Question

I am trying to remove all files with "(1)" in name under /mydir and sub directories. I have searched and found a script how to find all files with "*.txt" as below. How to replace the "if" condition sentense to find all files with "(1)" in name?

import os for root, dirs, files in os.walk("/mydir"): for file in files: **if file.endswith(".txt")**: os.remove(os.path.join(root, file))

Answer 1

You can do that like this:

import os
for root, dirs, files in os.walk("/mydir"):
    for file in files:
        if "(1)" in file:
            os.remove(os.path.join(root, file))

First we import the os module for walk , remove , and join methods. Then iterate over the tuples yielded by os.walk . Then iterate over the files returned and check whether the filename contains the string "(1)". If it matches, we concatenate the file name with the directory using os.path.join and then remove the file with os.remove .

Answer 2

You can do this very easy with pathlib :

from pathlib import Path
for file in Path("/mydir").glob("*(1)*.*"):
    print(file)
    #file.unlink()

My recommendation is to print all files to delete first (as shown), and only uncomment the file.unlink() line once you are sure that the right files will be deleted.
