Confirmed, you are not mistaken! - @rafael.guerra Thanks!

But the initial reason for my post is still open, why does the statement “`global s_files`” in my initial function does the opposite from what is expected, that it is not necessary in this situation is one thing, but that it does the opposite from what I would like to achieve (that it is made global over the whole function space) is strange to me.

`global s_files` would refer to the module scope outside the `rdir()` function, but this variable is there empty / not defined.

Local variables defined inside a function can be used inside the inner scope of for loops, annotating them as global would have the meaning above. But I might well be wrong.
