Step by step solution

Introduction to the "items" method

The "items" method is a built-in Python method that returns a view object displaying a list of a dictionary's key-value tuple pairs. This method is applied to dictionaries, making it easier to iterate through their elements.

Syntax of the "items" method

The syntax to use the "items" method is as follows: `dictionary.items()`. Replace "dictionary" with the variable name of the dictionary you want to apply this method to.

Example of using the "items" method

Let's consider the following example to better understand the use of the "items" method: ```python student_scores = { 'Alice': 85, 'Bob': 78, 'Charlie': 92 } ``` If we want to retrieve the key-value pairs from this dictionary using the "items" method, the code would look like this: ```python result = student_scores.items() print(result) ``` Running the above code, the following view object will be returned: ```python dict_items([('Alice', 85), ('Bob', 78), ('Charlie', 92)]) ```

Iterating through the key-value pairs

The view object returned by the "items" method can be further used to loop through the key-value pairs of the dictionary. Here's an example: ```python for key, value in student_scores.items(): print(key, value) ``` Output: ```python Alice 85 Bob 78 Charlie 92 ``` This code snippet iterates through the key-value pairs in the dictionary using the "items" method, printing each key and value.
