Copy Dictionaries

1. Shallow Copy using copy() method:

# Original Dictionary
original_dict = {'name': 'John', 'age': 30, 'city': 'New York'}

# Shallow Copy using copy() method
copy_dict = original_dict.copy()

2. Shallow Copy using dict() constructor:

# Original Dictionary
original_dict = {'name': 'John', 'age': 30, 'city': 'New York'}

# Shallow Copy using dict() constructor
copy_dict = dict(original_dict)

3. Deep Copy using copy module:

# Original Dictionary
original_dict = {'name': 'John', 'age': 30, 'city': ['New York', 'London']}

# Deep Copy using copy module
import copy
deep_copy_dict = copy.deepcopy(original_dict)

The methods mentioned above provide different ways to create copies of dictionaries in Python. Choose the method that best suits your needs. If your dictionary contains only basic data types, a shallow copy may be sufficient. If your dictionary contains nested objects, especially mutable ones, a deep copy may be more appropriate.
