如何从文件夹中的所有文件中删除具有特定字符串的行

import os

def delete_lines_with_string(folder_path, target_string):
    for filename in os.listdir(folder_path):
        file_path = os.path.join(folder_path, filename)
        if os.path.isfile(file_path):
            with open(file_path, 'r') as file:
                lines = file.readlines()
            
            filtered_lines = [line for line in lines if target_string not in line]
            
            with open(file_path, 'w') as file:
                file.writelines(filtered_lines)

# 示例调用
folder_path = '/path/to/folder'
target_string = '特定字符串'
delete_lines_with_string(folder_path, target_string)
