Is there a good reason for this?
The REPL requires an extra empty line to indicate the end of multi-line
constructs. You can see it by the prompt: as long as the REPL prints
'... ' as prompt, that means it puts everything you type in the same
multi-line construct. To enter a new multi-line construct (such as a
function definition, a for-loop, an if-statement, ...), press enter
directly at the prompt; the REPL should than use '>>> ' as the prompt again.
(Alternatives like IPython (https://ipython.readthedocs.io/en/stable/)
are a bit more loose regarding how to enter multi-line constructs)
