Dictionaries

Dictionaries in Python allow you to store key-value pairs, which is useful for representing objects or collections of data with a relationship.

Method	Brief description	Small descriptive example
`get()`	Returns the value associated with a key.	Gets the price of the product with key `"apple"`.
`keys()`	Returns a view with all the keys of the dictionary.	Lists all keys like `"name"`, `"age"`.
`values()`	Returns a view with all the values of the dictionary.	Lists all values like `"Anna"`, `25`.
`items()`	Returns a view with `(key, value)` pairs from the dictionary.	Iterates over key and value in a `for` loop.
`pop()`	Removes a key and returns its associated value.	Removes the `"user"` key and returns its content.
`popitem()`	Removes the last inserted key-value pair (in modern Python versions).	Removes the last added item.
`update()`	Adds or updates key-value pairs from another dictionary or parameters.	Adds `"city": "Bogota"` to the user dictionary.
`clear()`	Removes all elements from the dictionary.	Completely empties the configuration dictionary.
`copy()`	Returns a shallow copy of the dictionary.	Creates a copy of the user profile dictionary.
`setdefault()`	Returns the value of a key; if it does not exist, adds it with a default value.	Ensures `"email"` exists, otherwise assigns it `None`.
