How to Clone a Dictionary in Python

How to Clone a Dictionary in Python ?

Answer

To clone a dictionary in Python, you can use the copy() method for a shallow copy or the deepcopy() method from the copy module for a deep copy. This allows you to create a duplicate of the original dictionary.

✐ Examples

1 Cloning a Dictionary Using the `copy()` Method

We can clone a dictionary in Python using the copy() method. This example demonstrates how to declare and initialize a dictionary, use the copy() method to clone it, and print the cloned dictionary.

For example,

We start by declaring and initializing a dictionary named original_dict with integer keys and string values.
We use the copy() method to create a shallow copy of the original dictionary.
We print the cloned dictionary.

Python Program

original_dict = {
    1: 'One',
    2: 'Two',
    3: 'Three'
}

# Clone the dictionary using the copy() method
cloned_dict = original_dict.copy()

# Print the cloned dictionary
print('Cloned dictionary:')
for key, value in cloned_dict.items():
    print(f'Key: {key}, Value: {value}')

Output

Cloned dictionary:
Key: 1, Value: One
Key: 2, Value: Two
Key: 3, Value: Three

2 Cloning a Dictionary Using the `deepcopy()` Method

We can clone a dictionary in Python using the deepcopy() method from the copy module. This example demonstrates how to declare and initialize a dictionary, use the deepcopy() method to clone it, and print the cloned dictionary.

For example,

We start by importing the copy module.
We declare and initialize a dictionary named original_dict with integer keys and string values.
We use the deepcopy() method to create a deep copy of the original dictionary.
We print the cloned dictionary.

Python Program

import copy

original_dict = {
    1: 'One',
    2: 'Two',
    3: 'Three'
}

# Clone the dictionary using the deepcopy() method
cloned_dict = copy.deepcopy(original_dict)

# Print the cloned dictionary
print('Cloned dictionary:')
for key, value in cloned_dict.items():
    print(f'Key: {key}, Value: {value}')

Output

Cloned dictionary:
Key: 1, Value: One
Key: 2, Value: Two
Key: 3, Value: Three
