How to extract sublist from a list?
Hi everyone,
Suppose I have a list named "lst", see below:
> lst
$sub1
...
$sub1$x
...
$sub1$y
....
$sub2
...
$sub2$x
...
$sub2$y
?
$sub3
...
...
...
Now, I want to extract the sub-sublist $y from every sublist(sub1, sub2...)
and then storage them to a new list.
I know how to extract them by subscript or list name one by one, but I
wonder if there exist some tricks to finish this
