# A revised version that performs an actual list-to-list copy.


list1 = [1,2,3,4]
list2 = []

# Sucuessively copy the elements from one list to another.
for i in range (0, 4, 1):
    list2.append(list1[i])

# The change is only made one list in order to demonstrate that
# there exists two seperate lists.
print list1, list2
list1[1] = 99
print list1, list2
