What is the purpose of the get() method in a dictionary?

The get() method in a dictionary plays an essential role in accessing values based on their associated keys without the risk of encountering errors if the key does not exist. When using this method, you can specify a key, and if that key is found in the dictionary, the method returns the corresponding value. If the key is not found, rather than raising a KeyError as direct access would, it returns a default value if one is provided (or None if no default is specified). This functionality makes get() particularly useful for safely retrieving values from a dictionary in scenarios where the existence of a key cannot be guaranteed.

In contrast, adding a new key-value pair, retrieving all keys, or removing a key involves different methods and operations not related to the get() method. Specifically, the addition of a key-value pair is typically done using assignment, retrieving keys is accomplished with the keys() method, and the removal of a key is performed using the del statement or the pop() method.
