If you're looking for junior-ish python devs, I'd expect a good chunk of the better ones to have a python repl open and ready just as a matter of habit.

So for them, yes, it would clearly be faster to run the code than to work through it manually.

What you're doing here is selecting for candidates who are less comfortable with using the tools that they'd be expected to use every day in the role you're hiring for. It's likely to provide a negative signal.
