OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: [Python]

Question

我想重命名一个 mp3 文件。

   os.rename(f'C:\Users\axeld\Desktop\Music\NG  Trial\{item}',
             f'C:\Users\axeld\Desktop\Music\NG  Trial\{Song_name}')

但是我得到这个错误：

OSError: [WinError 123] The filename, directory name, or volume label syntax is incorrect: 'C:\Users\axeld\Desktop\Music\NG  Trial\109650.mp3' -> 'C:\Users\axeld\Desktop\Music\NG  Trial\Operation: Evolution.mp3'

我 100% 确定文件在那里，为什么我会收到此错误？

Answer 1

我没有 Windows 盒子可以试穿，但您是否考虑过使用 os.path.join 创建路径？

basedir = os.path.join('C:/', 'Users', 'axeld', 'Desktop', 'Music', 'NG  Trial')
old_name = os.path.join(basedir, item)
new_name = os.path.join(basedir, song_name)
os.rename(old_name, new_name)

来自documentation of os.path.join:

Join one or more path components intelligently. The return value is the concatenation of path and any members of *paths with exactly one directory separator (os.sep) following each non-empty part except the last, meaning that the result will only end in a separator if the last part is empty. If a component is an absolute path, all previous components are thrown away and joining continues from the absolute path component.

On Windows, the drive letter is not reset when an absolute path component (e.g., r'\foo') is encountered. If a component contains a drive letter, all previous components are thrown away and the drive letter is reset. Note that since there is a current directory for each drive, os.path.join("c:", "foo") represents a path relative to the current directory on drive C: (c:foo), not c:\foo.

注意最后一行，它记录了 Windows 的一个特例（另请参阅 answer on SO：这就是为什么在我上面的代码中 C: 之后有正斜杠。

备选方案

根据评论，os.path.join的方案还是会报错。作为解决方法，您可以使用原始字符串：

os.rename(
    r'C:\Users\axeld\Desktop\Music\NG Trial\{}'.format(item), 
    r'C:\Users\axeld\Desktop\Music\NG Trial\{}'.format(song_name))
