循环目录中的文件，统计每个文件中的行数，如果少于500行，则复制到新的文件名中

import os
import shutil

def count_lines(filename):
    with open(filename, 'r') as file:
        lines = file.readlines()
        return len(lines)

def copy_file(source, destination):
    shutil.copyfile(source, destination)

def process_directory(directory):
    for root, dirs, files in os.walk(directory):
        for file in files:
            filepath = os.path.join(root, file)
            line_count = count_lines(filepath)
            
            if line_count < 500:
                new_filename = f"new_{file}"
                new_filepath = os.path.join(root, new_filename)
                copy_file(filepath, new_filepath)

# 示例目录路径
directory_path = "/path/to/directory"

process_directory(directory_path)
