Python Program: Create a List of Tuples with Number and Its Cube

Introduction

In this blog post, we will explore how to write a Python program to create a list of tuples where each tuple contains a number and its cube. We’ll discuss the algorithm, provide a step-by-step explanation, present the Python code, and include examples with outputs.

Understanding the Algorithm

The algorithm for creating a list of tuples involves the following steps:

1. Input List: Take a list of numbers as input.

2. Create Tuples: For each number in the input list, create a tuple containing the number and its cube.

3. Build Result List: Append the tuples to a new list.

4. Output Result: Display the list of tuples as the output.

Python Program to Create a List of Tuples with Number and Its Cube

Let’s implement the algorithm in a Python program:

def create_tuples_with_cubes(input_list):
    # Create list of tuples with number and its cube
    result_list = [(num, num**3) for num in input_list]
    return result_list

# Example Usage
numbers_list = [1, 2, 3, 4, 5]
result_tuples = create_tuples_with_cubes(numbers_list)

print("List of Tuples with Number and Its Cube:")
for tpl in result_tuples:
    print(tpl)

Output Example

Example: Create List of Tuples with Number and Its Cube

List of Tuples with Number and Its Cube:
(1, 1)
(2, 8)
(3, 27)
(4, 64)
(5, 125)

Explanation

The program defines a function create_tuples_with_cubes that takes a list of numbers as input. It uses a list comprehension to create a new list of tuples where each tuple contains a number and its cube. The example uses the input list [1, 2, 3, 4, 5], and the output displays the resulting list of tuples.

Conclusion

Creating a list of tuples in Python is a common task, and it can be achieved elegantly using list comprehensions. This program demonstrates how to generate tuples with numbers and their cubes, offering a practical example of list manipulation.
