Making True Copy of a List With Python Programing



Making true copy of a list

Sometimes you need to make a copy of a list and you generally tend to to do it using the assignment , 

A = [1,2,3]

A = B

But it will not make be as duplicate list  of a.  Thus to make a true independent copy of a list we will use copy() method. 

L.copy()

the same thing that you did by using list and copy functions can also be achieved as:

Listcopy= list[:]


Ques : Write a program to create a copy of a list.In the list's copy, add 10 to its first and last elements. Then display the lists ?

 L1 = [17,24,15,30,34,27]

 L2 = L1.copy()

 print("Original List :",L1)

 print("Created copy of the list :",L2)

 L2[0] += 10

 L2[-1] += 10

 print("Copy of the list after changes :",L2)

 print("Original List :",L1)
