Python - 如何使用DateTime重命名文本文件

import os
from datetime import datetime

def rename_text_files(directory):
    now = datetime.now()
    date_time = now.strftime("%Y-%m-%d_%H-%M-%S")

    for filename in os.listdir(directory):
        if filename.endswith(".txt"):
            old_path = os.path.join(directory, filename)
            new_filename = filename.replace("OLD_TEXT", date_time)
            new_path = os.path.join(directory, new_filename)
            os.rename(old_path, new_path)

# 使用示例
directory = "path/to/your/directory"
rename_text_files(directory)
