In this tutorial, we will learn how to program "How to Create a Dictionary from Two Lists in Python." The objective is to create a dictionary from two lists — one containing keys and the other containing values. This tutorial will guide you step by step through the process of combining two lists into a dictionary. By the end of this tutorial, you will have a solid understanding of how to implement this task effectively in Python, helping you strengthen your problem-solving abilities and improve your coding skills.

This topic is straightforward to understand. Simply follow the instructions provided, and you will complete it with ease. The program will guide you step by step through the process of creating two lists from a dictionary. So, let’s dive into the coding process!

Getting Started:

First you will have to download & install the Python IDLE's, here's the link for the Integrated Development And Learning Environment for Python https://www.python.org/downloads/.

Creating Main Function

This is the main function of the application. The following code will display a simple GUI in terminal console that will display program. To do this, simply copy and paste these blocks of code into the IDLE text editor.

while True:
    print("\n============= Create a Dictionary from Two Lists =============\n")
 
    try:
        keys = []
        values = []
        n = int(input("Enter number of elements for dictionary: "))
 
        print("\nEnter keys:")
        for x in range(n):
            element = input(f"Enter key {x+1}: ")
            keys.append(element)
 
        print("\nEnter values:")
        for x in range(n):
            element = input(f"Enter value {x+1}: ")
            values.append(element)
 
        d = dict(zip(keys, values))
        print("\nThe dictionary is:")
        print(d)
 
    except ValueError:
        print("⚠ Please enter valid input.")
 
    opt = input("\nDo you want to try again? (yes/no): ").strip().lower()
    if opt == 'no':
        print("Exiting program...")
        break
    elif opt != 'yes':
        print("Invalid choice. Exiting program...")
        break

This program creates a dictionary from two user-input lists. It first asks how many elements the dictionary should have, then collects the keys and values separately. Using the `zip()` function, it pairs each key with its corresponding value to form the dictionary, which is then displayed. The program runs in a loop, allowing the user to repeat the process until they choose to exit.

Output:
