o= [1,2,3,3]
print('o:',id(o))
d= o
print('d:',id(d))
d= [1,2,3,4]
dd= o
print('dd:',id(dd))
dd[3]= 5

print('o:',o)
print('d:',d)
print('dd:',dd)

=======================
Output:
o: 1976210449032
d: 1976210449032
dd: 1976210449032
o: [1, 2, 3, 5]
d: [1, 2, 3, 4]
dd: [1, 2, 3, 5]

Though o,d and dd points to the same memory pointer but d has different value. How can same memory location points to 2 different values?
