can any one explain output of this code

Question

list1=[1, 3,4,5]
list2=list1
list2[0]=5
print(list1[0])

Answer 1

The output must be 5 because here the reference of list1 is assigned to list2. So there is a single list pointed by two objects. So the change in one means it will be reflected on the other as well.

Answer 2

Not equal - they are the same list.

Just like your mom is also your grandmother's daughter.
