How is this code "dividing" by a string?
I found a strange expression in some Python code: ``` python from library import HOME_DIRECTORY file = HOME_DIRECTORY / "file.json" ``` It seems to be dividing a string by another string in order to do something with files. However, I can't make this work in the REPL with my own strings: ```python >>> "one" / "two" Traceback (most recent call last): File "<stdin>", line 1, in <module> TypeError: unsupported operand type(s) for /: 'str' and 'str' ``` What is the code actually doing? Even if it didn't cause an error, I can't guess what dividing strings would mean, or why it would be useful.

copyedit for conciseness, clarity and correct use of terminology; include an explicit example instead of only citing an error message; improve title
Dividing strings in Python
- How is this code "dividing" by a string?
I'm not a Python developer, but I occasionally run across Python code, and I've encountered a weird syntax:- ``` python
- from library import HOME_DIRECTORY
- file = HOME_DIRECTORY / "file.json"
- ```
It seems to be dividing a string by another string, and thereby performing some file operation, but1) When I try to replicate this in the REPL, I get> TypeError: unsupported operand type(s) for /;2) I'm not sure what dividing strings would do even if I didn't get an error, and3) I'm not sure what is supposed to be accomplished by doing that.Can somebody explain what's going on here?
