我在一个文件夹中有许多文件。我想在处理完每个文件后删除它。

使用 os.remove() 和 os.unlink 有什么区别？哪种方法最适合我的场景？

Answer 1

注意:最初问这个问题时，它有一个 python-2.7 标签，此后已被删除。有关 Python 3 中所做更改的讨论，请参阅此答案的评论。

它们与 Python 2.7 documentation 中描述的相同。 :

os.<b>remove</b>(<i>path</i>) :

Remove (delete) the file path. If path is a directory, OSError is raised; see rmdir() below to remove a directory. This is identical to the unlink() function documented below. On Windows, attempting to remove a file that is in use causes an exception to be raised; on Unix, the directory entry is removed but the storage allocated to the file is not made available until the original file is no longer in use.

Availability: Unix, Windows.

os.<b>unlink</b>(<i>path</i>) :

Remove (delete) the file path. This is the same function as remove(); the unlink() name is its traditional Unix name.

Availability: Unix, Windows.
