I do agree that it's probably unnecessary here, but in many cases assigning to variables can be a good thing in the name of readability. You can give the variable a name, explaining it's purpose. If you directly return an expression, the reader will have to parse and understand the purpose of the expression to understand the context.

As of 3.10, the walrus operator is your friend if you really want to name to explain: return cached_foobar := cache.get("foobar").data

  Wouldn’t this throw an attribute error if cache.get didn’t return an object with .data?

    Yes, just as it would if you made the assignment on a line previous to the return statement. It would also error if there was no 'cache' in scope, and anything else you can imagine.
