怎么让 os.path.join 在 windows 下使用'/'而不是'\\'？

[XIVN1987]

windows 系统下执行：os.path.join('/abc/def', 'mnk')

结果是：'/abc/def\\mnk'

我想要的结果是：'/abc/def/mnk'

请问如何操作？

[Chase2E]

同问

[itskingname]

那么你就不要用 os.path.join，改成

```
path = ['/abc/def', 'mnk']
result = '/'.join(path)
print(result)
```

[wangyzj]

别用 os.path

@itskingname

多谢，，麻烦的方式有很多，，比如 os.path.join('/abc/def', 'mnk').replace('\\', '/')

提问是想看看有没有简单的方法

[wuwukai007]

os.path.join(abc,def,mnk)

[littleylv]

你本来就不应该把 /abc/def 写死，代码里写死路径分隔符是不好的习惯
不知道 python 有没有定义常量，PHP 有一个 DIRECTORY_SEPARATOR https://www.php.net/manual/en/dir.constants.php

[hhhsuan]

用 pathlib

[Trim21]

@littleylv 好像是 os.sep 还是 os.path.sep 来着

[Trim21]

手头没电脑，没法实际测试。你看看 urllib 里面的 join 行不行

[ClericPy]

pathlib 的 Path 对象有个 as_posix 就可以了, 何必非纠结 os.path 呢

[Cooky]

pathlib ？

[hhhsuan]

from pathlib import PurePosixPath

p = PurePosixPath("/abc/def")
p = p.joinpath("mnk")
print(p)

> /abc/def/mnk

[Procumbens]

import posixpath
posixpath.join()

From [os.path documentation]( https://docs.python.org/3/library/os.path.html):
Since different operating systems have different path name conventions, there are several versions of this module in the standard library. The os.path module is always the path module suitable for the operating system Python is running on, and therefore usable for local paths. However, you can also import and use the individual modules if you want to manipulate a path that is always in one of the different formats. They all have the same interface:
- posixpath for UNIX-style paths
- ntpath for Windows paths

@Procumbens

感谢，，感觉这个方法最好

[XIVN1987]

感觉 @Procumbens 提出的方法最简洁

只需要 import posixpath as path

然后把 os.path.join('/abc/def', 'mnk') 都替换成 path.join('abc/def', 'mnk') 就可以了，，

[yuankui]

os.path 不就是为了做跨平台兼容的吗？ window 用 /路径分隔符有啥意义？

[yucongo]

from pathlib import Path

Path('/abc/def', 'mnk').as_posix() # ->'/abc/def/mnk'

[XIVN1987]

@yuankui

如果合成的路径是要发到远程主机上使用的话就有意义了

[starix]

os.sep

[BlueSummer8]

用 str 的 join 怎样，'/'.join(('aaa', 'bbb'))
