Use copy() method to copy the dictionary in Python. This method returns a copy (shallow copy) of the dictionary and doesn’t take any parameters.
dict.copy()Example how to copy a dictionary in Python
Simple example code.
original = {1: 'A', 2: 'B'}
copy_dict = original.copy()
print(copy_dict)Output:
If you need a deep copy (a copy that does not share references to the original object), you can use the copy module:
import copy
original_dict = {'key1': [1, 2], 'key2': 'value2'}
new_dict = copy.deepcopy(original_dict)
How is it different from simple assignment “=”?
Answer: Copying the dictionary using the copy() method creates a copy of the references from the original dictionary.
Where the = operator creates a new reference to the original dictionary is created.
original = {1:'one', 2:'two'}
new = original
# removing all elements from the list
new.clear()
print('new: ', new)
print('original: ', original)Output:
new: {}
original: {}
