How do you combine paths in the operating system using the os module in Python?

In Python, the os.path.join function from the os module is used to combine paths in the operating system.

It correctly joins path parts, considering the separator conventions of the specific OS (for example, / in Unix and \ in Windows).

Example:

import os

path = os.path.join('folder', 'subfolder', 'file.txt')
print(path)  # In Unix: folder/subfolder/file.txt
              # In Windows: folder\subfolder\file.txt

This is more convenient and safer than simply concatenating strings, as it accounts for the correct separators and prevents errors.
