Difference between shallow copy and deep copy

It means that any changes made to a copy of the object do not reflect in the original object. In python, this is implemented using “deepcopy()” function. whereas in shallow copy any changes made to a copy of an object do reflect in the original object. In python, this is implemented using the “copy()” function.

Example 1: Using copy()

Unlike copy(), the assignment operator does deep copy. 

Output: 

new:  {}
original:  {1: 'geeks', 2: 'for'}
new:  {}
original:  {}

Example 2: Using copy.deepcopy

Unlike deepcopy(), the assignment operator does deep copy. 

Output: 

new:  {}
original:  {1: 'geeks', 2: 'for'}
new:  {}
original:  {}

Python Dictionary copy() method returns a shallow copy of the dictionary. let’s see the Python Dictionary copy() method with examples:

 Examples

Input: original = {1:'geeks', 2:'for'}
        new = original.copy() // Operation
        
Output: original:  {1: 'one', 2: 'two'}
         new:  {1: 'one', 2: 'two'}
