Python 代码：批量替换文件名中的 '+' 为 '：'

import os

folder_path = r'C:\Users\Administrator\Desktop\xuexi'

for root, dirs, files in os.walk(folder_path):
    for file in files:
        old_name = os.path.join(root, file)
        new_name = os.path.join(root, file.replace('+', ':'))
        os.rename(old_name, new_name)
