Answer 3

pop operation removes the element from the list,
Given list:-
a=[1,2,3,4,5,6,7]
So range is from 0 to 3 i.e (0,1,2)
for i =0, a.pop(0) removes 1 from the list, so now a = [2,3,4,5,6,7]
for i =1, a.pop(1) removes 3 from the list, so now a = [2,4,5,6,7]
for i =2, a.pop(2) removes 5 from the list, so now a = [2,4,6,7]

and at print(a), we get[ 2,4,6,7] as final outpout
