Python Copy objects (deep copy deepcopy and light copy copy) _python

1. Copy.copy a shallow copy copies only the parent object and does not copy the inner child objects of the object.
2. Copy.deepcopy deep Copy object and its child objects
A good example:

--> ImportCopy
A=[1,2,3,4, ['A','B']]#Original Object

B=A#Assignment, passing a reference to an object
C=Copy.copy (a)# object copy, shallow copy
D = copy.deepcopy (a) # object copy, deep copy

A.append (5) # Modify Object A
a[4].append ('C') # Modify the [' A ', ' B '] Array object in Object a

Print 'a = ', a
Print 'b = ', b
Print 'c = ', C
print 'd = ', D

Output results:
A = [1, 2, 3, 4, [' A ', ' B ', ' C '], 5]
b = [1, 2, 3, 4, [' A ', ' B ', ' C '], 5]
c = [1, 2, 3, 4, [' A ', ' B ', ' C ']]
D = [1, 2, 3, 4, [' A ', ' B ']]
