get unix style path join in python-CodePudding

While making a wsgi app I am in need of joining route names like /apple, apple/buy etc.

    import os
    path = os.path.join("/apple/", "/buy")
    print("route path:", path)

Now the problem is it works fine in *nix systems but on dos ones the ouput could become:

    route path: apple\buy

cuz what is wanted was unix style paths like - apple/buy

is their a way that I can always get unix style paths? should I use something other than os module?

CodePudding user response：

os.path is a alias to posixpath or ntpath. You can import one of those modules directly to get the path rules you want. So, import posixpath and use functions like posixpath.join.

>>> import os
>>> os.path.__name__
'posixpath'
>>> import posixpath
>>> posixpath.join is os.path.join
True
>>>

You could

import os
import posixpath
os.path = posixpath

But that can be a bad choice because it would also affect any code that wants to work with local platform paths. Its usually best to use posixpath directly as needed.

os.path is for path operations on the current operating system. Use urllib.parse.urljoin to join URL paths.
