Python program to copy dictionaries

A dictionary contains the pair of the keys & values (represents key : value), a dictionary is created by providing the elements within the curly braces ({}), separated by the commas.

There are some of the ways to copy dictionaries,

Using the copy() method
Using the dict() method

1) Copy dictionaries using the copy() method

The copy() method is a built-in method in Python, which can be used to create a copy of the dictionary.

Syntax:

dictionary2 = dictionary1.copy()

Program:

# Python program to copy dictionaries # using the copy() method # creating the dictionary dict_a = {'id' : 101, 'name' : 'Amit', 'age': 21} # creating a copy dict_b = dict_a.copy() # printing the dictionaries print("Dictionary \'dict_a\' is...") print(dict_a) print("Dictionary \'dict_b\' is...") print(dict_b)

Output:

Dictionary 'dict_a' is... {'age': 21, 'id': 101, 'name': 'Amit'} Dictionary 'dict_b' is... {'age': 21, 'id': 101, 'name': 'Amit'}

2) Copy dictionaries using the dict() method

The dict() method is a built-in method in Python, which is used to create a new dictionary and can also be used to create a copy of the dictionary by creating a new dictionary from an existing dictionary.

Syntax:

dictionary2 = dict(dictionary1)

Program:

# Python program to copy dictionaries # using the dict() method # creating the dictionary dict_a = {'id' : 101, 'name' : 'Amit', 'age': 21} # creating a copy dict_b = dict(dict_a) # printing the dictionaries print("Dictionary \'dict_a\' is...") print(dict_a) print("Dictionary \'dict_b\' is...") print(dict_b)

Output:

Dictionary 'dict_a' is... {'id': 101, 'name': 'Amit', 'age': 21} Dictionary 'dict_b' is... {'id': 101, 'name': 'Amit', 'age': 21}
