A dictionary is a collection of key-value pairs that maps each unique key to a value. To get the value associated with a given key, you can use the square bracket notation dict[key] or the get() method dict.get(key)¹.

The square bracket notation will return the value of the key if it exists in the dictionary, or raise a KeyError exception if it does not¹. For example:

The get() method will return the value of the key if it exists in the dictionary, or a default value if it does not². The default value is None if not specified, but you can provide any other value as a second argument³. For example:

If you want to get a list of all the values in a dictionary, you can use the values() method, which returns a view object that contains the values of the dictionary¹. You can convert this view object to a list by using the list() function². For example:
