Hello Everyone,
I would like to know if it is possible to extract a sub-list from a
list ?
typically if :
L =[[1, 2, 3],[4, 5, 6],[3] ]
How to extract easily the elements 0 and 2 of L in order to get :
L2 =[[1, 2, 3],[3] ]
L2 = [L[0],L[2]]
Moreover, I would like to know if it is possible to use logical
indexation such that :
index = [ True, False, True]
L2 = L
use zip(index,L) in a for loop
or usual indexation, something like
index=[0, 2]
L2 = L
#untried
L2=[]
for i in index
L2.append(L[i])
