How to install the Python path module?

In Python, the `path` module is not a standalone module, but rather a sub-module of the `os` module. Therefore, you do not need to install the `path` module separately as it comes pre-installed with Python’s standard library. You can access the functionalities of the `path` module by importing it in the following way:

import os.path

Then, you can use `os.path` to access various methods and attributes of the `path` module, such as `os.path.join()` for joining paths, and `os.path.abspath()` for getting the absolute path.

import os.path
# 使用os.path模块的join方法连接路径
path = os.path.join("dir", "subdir", "file.txt")
print(path)
# 使用os.path模块的abspath方法获取绝对路径
absolute_path = os.path.abspath(path)
print(absolute_path)

In this way, you can now utilize the functionalities provided by the `path` module. Please note that the methods and attributes in the `path` module are all prefixed with `os.path`.
