How to Quickly Append Key:Value Pairs from One Dictionary to Another in Python

Creating a multiple-choice quiz using Python is a fun yet challenging endeavor. One common requirement for such a program is to allow users to retake only the questions they answered incorrectly. In this guide, we'll dive into how to append incorrect questions from one dictionary to another while ensuring a smooth end-user experience.

Understanding the Problem

Imagine you have a dictionary containing all your quiz questions as keys and their corresponding correct answers as values. When users take the quiz, they usually answer some questions incorrectly. To enhance learning, you want to collect these incorrect answers in a separate dictionary, enabling users to retake only those questions. However, achieving this may seem complex at first, especially if you're unfamiliar with dictionary operations in Python.

Initial Code Overview

Here's the basic outline of the quiz code to illustrate the concept:

How to Append Incorrect Questions

Following is a structured approach to modifying your existing code to efficiently append incorrect responses to a new dictionary:

Step 1: List of Tuples

Change the structure of the Questions dictionary to a list of tuples:

Each tuple contains a question as the first element and the correct answer as the second.

Step 2: Initialize Incorrect Questions List

Instead of creating an empty dictionary at the start, prepare a list of indexes that will store incorrect answers for easy manipulation later:

Step 3: Iterate Using While Loop

Instead of using a for loop, use a while loop to allow modifications to inc_questions based on user responses. This way, you can simply pop removed questions:
