[Python]批量重命名，修改文件名中的部分字符串

```Python
#202506113 update
import os

root_dir = r"D:\Dir"
old = "https://www.google.com/"
new = "https://m.google.com/"

for root, _, files in os.walk(root_dir):
    for file in files:
        if file.endswith('.xml'):
            full_path = os.path.join(root, file)
            with open(full_path, 'r', encoding='utf-8') as f:
                content = f.read()
            if old in content:
                content = content.replace(old, new)
                with open(full_path, 'w', encoding='utf-8') as f:
                    f.write(content)
                print(f"✅ 替换完成: {full_path}")
            else:
                print(f"⏩ 未发现目标字符串: {full_path}")

```

上一版PowerShell版本的莫名其妙的有些改不了：https://www.cnblogs.com/alfredsun/p/10124230.html

 

 

 

更新一个Python版本：

import os
files = os.listdir(os.getcwd())
for file in files:
    os.rename(file,file.replace('FLAC','FLACx2'))

 

效果：
