python删除文件夹里的指定文件

import os

def delete_file_from_folder(folder_path, file_name):
    # 构建文件的完整路径
    file_path = os.path.join(folder_path, file_name)
    
    # 检查文件是否存在
    if os.path.isfile(file_path):
        try:
            # 删除文件
            os.remove(file_path)
            print(f"文件 {file_name} 已成功删除。")
        except Exception as e:
            print(f"删除文件时出错: {e}")
    else:
        print(f"文件 {file_name} 不存在于 {folder_path} 中。")

# 使用示例
folder_path = 'path/to/your/folder'  # 替换为你的文件夹路径
file_name = 'example.txt'           # 替换为你想要删除的文件名
delete_file_from_folder(folder_path, file_name)

import os
import stat

def remove_readonly(func, path, _):
    "Clear the readonly bit and reattempt the removal"
    os.chmod(path, stat.S_IWRITE)
    func(path)

try:
    os.remove(file_path)
except PermissionError as e:
    os.chmod(file_path, stat.S_IWRITE)  # 修改文件权限
    os.remove(file_path)
