for sure. that was more for expository purpose rather than how i was
planning to go about it.

above or equivalent list comprehension was what i had in mind as far
as linear search goes. and scanning the list like this will most
likely be 'good enough' performance-wise. however, partly just out of
curiosity, i was wondering if there is some kind of data structure
which might let me find all the matches a bit faster.
