Hope you are doing well

When you use deepcopy , it constructs a new compound object and then, recursively, inserts copies into it of the objects found in the original. In short, you will have two different blocks containing same elements.Hence, append on one list will not affect other. Kindly check below example:

import os
import copy

a = [1,2,3,4]

b = [100,200,300,400]

print ("elements in a", a)

print ("elements in b", b)

a=b

print ("new elements in a", a)

print ("elemenst in b", b)

print ("Assingning a deepcopy will create complete new block with the same elements ")

a = copy.deepcopy(b)

print ("elements in a", a)

print ("elements in b", b)

a.append(100)

print ("new elements after append",a)

print ("let's check b", b)

print ("lets do some append on b")

b.append(1)
b.append(2)

print ("elements in a", a)
print ("elements in b", b)
