Python将str转换为路径类型? [英] Python convert a str to path type?

问题描述

我正在尝试与一些保存配置的现有代码交互，并期望文件路径为'path.path'类型.该代码期望从pygtk浏览器窗口返回文件路径(通过另一个函数).我想在代码的其他地方调用save_config函数，该文件的路径基于由字符串元素构成的基于不同输入的文件路径.

I am trying to interface with some existing code that saves a configuration, and expects a file path that is of type 'path.path'. The code is expecting that the file path is returned from a pygtk browser window (via another function). I want to call the save_config function elsewhere in my code with a file path based on different inputs, constructed from string elements.

当我尝试运行代码时，我能够正确地构造文件路径，但是它是字符串类型，并且save函数期望使用'path.path'类型.

When I try to run the code, I am able to construct the file path correctly, but it is a string type, and the save function expects a 'path.path' type.

是否可以将字符串转换为路径类型?我尝试搜索，但是只能找到相反的情况(字符串的路径).我也尝试使用os.path.join()，但是它也会返回一个字符串.

Is there a way to convert a string to a path type? I've tried searching, but could only find the reverse case (path to string). I also tried using os.path.join(), but that returns a string as well.

如果有所不同，这是python 2.7.

edit: This is python 2.7, if that makes a difference.

推荐答案

自python 3.4起:

Since python 3.4:

from pathlib import Path
str_path = "my_path"
path = Path(str_path)
