I'd be more inclined to day that let mostly encourages you to write zillion-line functions (instead of lots of small ones), simply because with it you "mentally can" since you can see the scope of variables better. But.. do you really prefer to write huge functions instead of smaller ones? Also: I think Python's default args being evaluated at function definition time kills the need for the usage of let when defining closures inside loops (you can just pas the value you want to capture in a closure as the default value of a param) or other things like that.

That’s true. I revise my comment as "Any piece of code that uses a variable[ to hold something you use multiple times and don’t want to recompute]."; for example creating an API client then using it twice.
