The clear() method in Python is a built-in method that is used to remove all the elements (key-value pairs) from a dictionary. It essentially empties the dictionary, leaving it with no key-value pairs.
In Python, the get() method is a pre-built dictionary function that enables you to obtain the value linked to a particular key in a dictionary. It is a secure method to access dictionary values without causing a KeyError if the key isn’t present.
In Python, the items() method is a built-in dictionary function that retrieves a view object containing a list of tuples. Each tuple represents a key-value pair from the dictionary. This method is a convenient way to access both the keys and values of a dictionary simultaneously, and it is highly efficient.
The keys() method in Python returns a view object with dictionary keys, allowing efficient access and iteration.
Python’s update() method is a built-in dictionary function that updates the key-value pairs of a dictionary using elements from another dictionary or an iterable of key-value pairs. With this method, you can include new data or merge it with existing dictionary entries.
The values() method in Python returns a view object containing all dictionary values, which can be accessed and iterated through efficiently.
In Python, the pop() method is a pre-existing dictionary method that removes and retrieves the value linked with a given key from a dictionary. If the key is not present in the dictionary, you can set an optional default value to be returned.
In Python, the popitem() method is a dictionary function that eliminates and returns a random (key, value) pair from the dictionary. As opposed to the pop() method which gets rid of a particular key-value pair based on a given key, popitem() takes out and gives back a pair without requiring a key to be specified.

In fact, in some cases, the list and dictionary methods share the same name. (In the discussion on object-oriented programming, you will see that it is perfectly acceptable for different types to have methods with the same name.) The following is an overview of methods that apply to dictionaries: d.clear() Clears a dictionary.

Oct 9, 2023 · This is another important detail of a Python dictionary: its keys are unique. If you update the value associated with a given key, its previous value is lost. Python dictionaries cannot have duplicate keys! Getting All Keys and Values. We can use the dict.keys() and dict.values() methods to view the dictionary’s keys and values, respectively:
