Chapter 10: Problem 13

What does the values method return?

Short Answer

Expert verified
The "values" method, when used with dictionaries in Python, returns a view object that displays a list of all the values in the dictionary. For instance, if we have a dictionary `example_dict = {'key1': 'val1', 'key2': 'val2', 'key3': 'val3'}` and we use the "values" method like `example_dict.values()`, it will return a view object containing `['val1', 'val2', 'val3']`.

Step by step solution

01

Understanding Python dictionaries

A dictionary is a mutable, unordered collection of key-value pairs, where each key must be unique. In Python, we can create a dictionary using curly brackets `{}` and separate keys and values by a colon `:`. For example: `example_dict = {'key1': 'val1', 'key2': 'val2', 'key3': 'val3'}`
02

Using the values method

Once we have a dictionary, we can use the "values" method to access its values. The syntax for using this method is: `dictionary.values()`. It returns a view object that displays a list of all the values in the dictionary. For example, using our `example_dict` from Step 1: ``` values_list = example_dict.values() ``` `values_list` will be a view object containing `['val1', 'val2', 'val3']`.
03

Examples

Let's look at a few examples to better understand the "values" method: Example 1: ``` grades = {'John': 90, 'Alice': 85, 'Bob': 78} grades_values = grades.values() ``` In this example, the `grades_values` variable will be a view object containing `[90, 85, 78]`. Example 2: ``` fruits = {'apple': 5, 'banana': 3, 'orange': 8} fruits_values = fruits.values() ``` In this example, the `fruits_values` variable will be a view object containing `[5, 3, 8]`. In conclusion, based on the context of Python dictionaries, the "values" method returns a view object that displays a list of all the values in a dictionary.
