Python convert a str to path type?
提问by realityinabox
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.
我正在尝试与一些保存配置的现有代码进行交互，并且需要一个类型为“path.path”的文件路径。该代码期望从 pygtk 浏览器窗口（通过另一个函数）返回文件路径。我想使用基于不同输入的文件路径在我的代码中的其他地方调用 save_config 函数，该文件路径由字符串元素构成。
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.
当我尝试运行代码时，我能够正确构造文件路径，但它是一个字符串类型，并且保存函数需要一个 'path.path' 类型。
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.
有没有办法将字符串转换为路径类型？我试过搜索，但只能找到相反的情况（字符串路径）。我也尝试使用os.path.join()，但这也会返回一个字符串。
edit: This is python 2.7, if that makes a difference.
编辑：这是 python 2.7，如果这有区别的话。

If path.pathrepresents a type, you can probably create an instance of that type with something like:
如果path.path代表一种类型，您可能可以使用以下内容创建该类型的实例：
string_path = "/path/to/some/file"
the_path = path.path(string_path)
save_config(the_path()

Maybe that answer worked for python 2.7, if you are on Python 3 I like:
也许这个答案适用于 python 2.7，如果你使用的是 Python 3，我喜欢：
import os
p = "my/path/to/file.py"
os.path.normpath(p)
'my\path\to\file.py'

Since python 3.4:
从 python 3.4 开始：
from pathlib import Path
str_path = "my_path"
path = Path(str_path)
