Python - copy dictionary

In this article, we would like to show you how to copy dictionary in Python.

Quick solution:

xxxxxxxxxx

dict2 = dict1.copy()

In this example, we use copy() method to create a copy of my_dict dictionary.

xxxxxxxxxx

my_dict = {

    "id": 1,

    "name": "Tom",

    "age": 25

}

​

dict_copy = my_dict.copy()

​

print(dict_copy.items())  # [('id', 1), ('name', 'Tom'), ('age', 25)]

Output:

xxxxxxxxxx

dict_items([('id', 1), ('name', 'Tom'), ('age', 25)])

Note:

You can't simply use dict2 = dict1, because dict2 will only be a reference to dict1. Any change in dict1 will automatically cause the change in dict2.
