Answer:
plist2 = plist1 [k:]
Explanation:
In this statement plist2 is a list which holds the elements of the list plist1 from k.
k is used here as an index of plist1. This is used in plist1 as an index of some element. k is of a positive integer type. Here we can see (:) after k which shows that plist2 contains all elements from index k of plist1 to the end of the plist1. This plist1 contains at least the elements from kth index to beyond it (k+1).
This means that the list named as plist2 is assigned all the elements of the list plist1 from the kth index to the end (beyond) of plist1.
