Which function retrieves only the values from a dictionary?

• A. values()
• B. get_values()
• C. extract_values()
• D. all_values()

Answer: (A)

The function that retrieves only the values from a dictionary in Python is the values() function. This built-in method returns a view object that displays a list of all the values stored in the dictionary, making it particularly useful when you need to work with or process the values without considering the associated keys. For example, if you have a dictionary like `my_dict = {'a': 1, 'b': 2, 'c': 3}`, calling `my_dict.values()` would return a view of the values: `[1, 2, 3]`. This function enables straightforward access to the data within the dictionary, allowing for operations such as looping through the values, converting them to a list, or performing calculations. The other options provided do not represent valid Python methods for retrieving dictionary values. Using those would result in an error since they are not part of the dictionary API, making `values()` the only correct choice among the options listed.
