[jar1]

I think it’s that Python buffers stdout by default and Julia doesn’t.

Why is printing to a terminal slow?

A different use of printing to stdout/stderr is to pipe output through less (or similar pager) to be able to inspect the output interactively without having to do a full (long) run. E.g. grep for certain strings in the output to check a condition, then letting the program continue until the next matching line, etc. I find this very useful during development. In this case you will also hit upon the slower output of Julia compared to Python. A simple (rough, due to the user keyboard interaction)…
