Hi Shiyao,
Now I see, that it was kind of dumb question...
x = ([1, 2], [3, 4], [5, 6])
L = []
[L.extend(i) for i in x]
[None, None, None]
Using a list comprehension for the expression side-effect, when you do
not actually want the list produced by the comprehension, is considered
bad style by many. There is nothing wrong with explicit loops.
BUT when I check L itself I'll see this one
L
[1,2,3,5,6]
