问题：Python，在目录字符串中添加尾部斜线，独立于操作系统

如果尾部斜杠尚不存在，如何在目录字符串中添加尾部斜杠（/对于* nix，\对于win32）？谢谢！

How can I add a trailing slash (/ for *nix, \ for win32) to a directory string, if the tailing slash is not already there? Thanks!

os.path.join(path, '') 如果末尾不存在斜线，则会添加该斜线。

你可以做os.path.join(path, '', '')或os.path.join(path_with_a_trailing_slash, '')你仍然只会得到一个尾部的斜杠。

os.path.join(path, '') will add the trailing slash if it’s not already there.

You can do os.path.join(path, '', '') or os.path.join(path_with_a_trailing_slash, '') and you will still only get one trailing slash.

由于要连接目录和文件名，请使用

os.path.join(directory, filename)

如果要摆脱.\..\..\blah\路径，请使用

os.path.join(os.path.normpath(directory), filename)

Since you want to connect a directory and a filename, use

os.path.join(directory, filename)

If you want to get rid of .\..\..\blah\ paths, use

os.path.join(os.path.normpath(directory), filename)

您可以通过以下方式手动进行操作：

path = ...

import os
if not path.endswith(os.path.sep):
    path += os.path.sep

但是，通常使用起来更清洁os.path.join。

You can do it manually by:

path = ...

import os
if not path.endswith(os.path.sep):
    path += os.path.sep

However, it is usually much cleaner to use os.path.join.

您可以使用如下形式：

os.path.normcase(path)
    Normalize the case of a pathname. On Unix and Mac OS X, this returns the path unchanged; on case-insensitive filesystems, it converts the path to lowercase. On Windows, it also converts forward slashes to backward slashes.

否则，您可以在此页面上寻找其他内容

You could use something like this:

Else you could look for something else on this page
