What is / in python?

Question

I'm wondering about / in python.

I know that it divides two integers, but I've seen something like this

'NAME': BASE_DIR / 'db.sqlite3'

For a `Path` from `pathlib` the `/` operator is overwritten and joins both sides into a new path. — Klaus D., Jul 08 '21 at 03:55
In Python, any type can define their own functionality for the action of operators. Probably, just guessing by the context, these are `pathlib.Path` objects — juanpa.arrivillaga, Jul 08 '21 at 03:59

Python allows defining the behaviour of operators when applied to custom classes using specially named methods ("dunders", from "double-underline"), as described here. The / operator's behaviour can be defined by .__truediv__(self, other) method. It is almost certainly the case here that BASE_DIR is an instance of pathlib.Path, which defines / as semantically equivalent to os.path.join for strings. You can read more here.

BASE_DIR is pathlib.Path object which supports the / operator for joining paths. You need to either use / or use os.path.join if you use strings.
