[Tutor] Splitting long string into same len parts

[Victor Bouffier]

Aha!!!
I believe this is what I was looking for in the first place (not that I
will use it anyway, given the alternatives provided by others).

I guess that coming from a Perl background, which as you know includes
regexes as part of the core language, you tend to look to all solutions
through this lens. I faced this problem before and solved it using
regexes but could not remember how.
Your re.findall() suggestion is nice though. Very clean.

Thanks Danny.
