If you multiply the inner list, you'll get a list containing 15 times the same mutable list object. You won't be able to modify one later without changing the others, because there will be no other list. The first multiplication is not a problem here, because strings are immutable in Python.
Hearing Conor give a full talk about Python is almost like hearing him speak Polish
Great talk, that was so insightful. Thanks Conor.
The digressions are just great !
@code_report in 45:40 why not multiply the inner list instead list comperhansion

No way i am refactoring my loops into double-list-comprehensions, thanks
