Python dictionaries are powerful data structures that allow you to store and retrieve data using key-value pairs. Appending an item to a list within a dictionary involves accessing the list by its corresponding key and then using the append method to add the new item to the list in Python. In Python, we can append to a list in a dictionary in several ways, we are explaining some generally used methods which are used for appending to a list in Python Dictionary. In this method, we will use conditions for checking the key and then append to a dictionary list using the list append method. In this method, we are using the defaultdict function. It is a part of the collections module. We have to import the function from the collections module to use it in the program and then use it to append to a dictionary list. Since append takes only one parameter, to insert another parameter, repeat the append method. We will use the Python dictionary update function to add a new list to the dictionary. We can use the update function to embed a dictionary inside another dictionary. You can convert a list into a value for a key in a Python dictionary using dict function. The extend method is used to append elements from an iterable, such as a list, to the end of another list. It modifies the original iterable in place by adding elements from the provided iterable. It then extends the list with additional values [35, 40] and prints the modified dictionary.

A dictionary in Python is a group of unordered items, each of which has a unique set of keys and values. Any immutable data type, such as a string, number, or tuple, can be used as the key. It serves as an exclusive identifier for the value in the dictionary. The value is repeatable and applicable to all types of data.
