Python Dictionary Methods

Q1: What is a Python Dictionary?

In Python, a dictionary is like a container that holds an assortment of key-value pairs, It’s a fundamental way to organize data where each piece of information is known as a “Key”. The Dictionary doesn’t impose any specific order on these pairs, so you can’t rely on the sequence in which they were added.

Q2: How we can access values in a Python dictionary?

We can access values in a Python dictionary by using the keys as the index: Below is the code:

my_dict = {“name”: “Kin”, “age”: 23, “city”: “London”}

print(my_dict[“name”]) #kin

print(my_dict[“age”]) #23

print(my_dict[“city”]) #London

Q3: What happens when we try to access a key that doesn’t exist in the dictionary?

When we try to access a key that doesn’t exist in the dictionary, Python will raise a ‘KeyError’. You can use the ‘get()’ method.

Q4: How do we remove an item from a dictionary?

To remove an item (key-value pair) from a dictionary, you can use the ‘pop()’ method, specifying the key to be removed.

Python dictionary methods is collection of Python functions that operates on Dictionary.

Python Dictionary is like a map that is used to store data in the form of a key: value pair. Python provides various built-in functions to deal with dictionaries. In this article, we will see a list of all the functions provided by Python to work with dictionaries.
