Adding a new key/value pair to a dictionary is straightforward in Python. The following code example shows us how to add a new key/value pair to a Python dictionary. dictionary = {"key1": "value1", "key2": "value2", "key3": "value3"} print(dictionary) dictionary["key4"] = "...
In Python, we can add multiple key-value pairs to an existing dictionary. This is achieved by using theupdate()method. This method takes an argument of typedictor any iterable that has the length of two - like((key1, value1),), and updates the dictionary with new key-value pairs. If...
In Python, the|(pipe) operator, also known as the union operator, provides a concise and intuitive way to add a dictionary to another dictionary. This operator performs a union operation on the dictionaries, merging their key-value pairs into a new dictionary. ...
The dictionary unpacking operator (**) is an awesome feature in Python. It allows you to merge multiple dictionaries into a new one, as you did in the example above. Once you’ve merged the dictionaries, you can iterate through the new dictionary as usual....

In the following example, we are going to read a JSON file and then print out the data in the form of a dictionary. Thisjson.load()function reads the string from the JSON file. The json.load(file) function creates and returns a new Python dictionary with the key-value pairs in the ...
dictionary = { 1:"integer", 2.03:"Decimal", "Lion":"Animal"} In the above dictionary: “integer” is a value of key “1” “Decimal” is a value of key “2.03” “Animal” is a value of key “Lion” Different ways to initialize a Python dictionary We can define or initialize ...
Method 2: Initialize a Dictionary in Python Using “{}” Braces Method Another easiest way to initialize the dictionary in Python is using the curly braces “{}” method. Example To initialize the empty dictionary, use the “{}” braces: ...
Theupdate()method is one of the simplest ways to concatenate dictionaries in Python. It updates the dictionary with elements from another dictionary. Syntax: Here is the syntax: dict1.update(dict2) Example: Here is an example. config1 = {'host': 'localhost', 'port': 8080} ...
