dictionaries in python are versatile data structures that allow you to store and retrieve data using key-value pairs. adding new key-value pairs to a dictionary is a common operation in python. in this tutorial, we will explore various methods to add key-value pairs to a dictionary, along with code examples.
the most straightforward way to add a key-value pair to a dictionary is by using square bracket notation. if the key already exists, the associated value will be updated; otherwise, a new key-value pair will be created.
output:
the update() method is another way to add multiple key-value pairs to a dictionary. it takes a dictionary or an iterable of key-value pairs as an argument and adds them to the existing dictionary.
output:
you can also use the dict() constructor to create a new dictionary or update an existing one by passing key-value pairs as arguments.
output:
choose the method that best fits your requirements, based on the specific use case and your coding preferences. adding key-value pairs to dictionaries in python is a fundamental skill that you'll frequently use in your programming journey.
