Au contraire! Remember, that brevity is the sister of talent.
I would definitively vote for
labels = [make_label(then, name) for then, name in mylist]
(always use descriptive names of functions and variables;
auxfunc is a short way to the hell)
Beauty of the list comprehensions is that they show nicely what
list is being processed, how it is filtered (if at all), and
what we do with each element of the generated list. Anything you
add to this simplicity is wrong. Whenever you start to feel you
are missing some methods how to stuff more commands into
a comprehension (or for example multiple embedded ones), you
should start new function.
The same rule applies here as with any other lambda function
(because these are in fact lambda functions): the best way how
to write lambda is to write algorithm somewhere on the side,
describe what this function does in one word, then add `def` in
front of that name, and use so created named function instead.
Best,
Matěj
