如何删除许多文件中所有的#注释掉行？

import os

def remove_comments(file_path):
    # 读取文件内容
    with open(file_path, 'r') as file:
        lines = file.readlines()

    # 删除注释行
    modified_lines = []
    for line in lines:
        if not line.startswith('#'):
            modified_lines.append(line)

    # 保存修改后的文件内容
    with open(file_path, 'w') as file:
        file.writelines(modified_lines)

def process_directory(directory_path):
    # 遍历目录下的所有文件和子目录
    for root, dirs, files in os.walk(directory_path):
        for file in files:
            file_path = os.path.join(root, file)
            # 处理文件
            remove_comments(file_path)

# 指定要处理的目录
directory_path = '/path/to/directory'

# 执行处理
process_directory(directory_path)
