Add Elements to a Dictionary in Python

  • Post category:Dictionary

In Python, dictionaries are mutable, which means you can add new elements or update existing ones easily. Let’s explore different methods to add elements to a dictionary.

Method 1: Using Square Brackets

# Method 1: Using Square Brackets
my_dict = {"name": "John", "age": 30}
my_dict["city"] = "New York"
print(my_dict)

Output:

{‘name’: ‘John’, ‘age’: 30, ‘city’: ‘New York’}

Method 2: Using the update() Method

# Method 2: Using the update() Method
my_dict = {"name": "John", "age": 30}
my_dict.update({"city": "New York"})
print(my_dict)

Output:

{‘name’: ‘John’, ‘age’: 30, ‘city’: ‘New York’}
