Modulo-Magic

The Divisibility Range Tool is a Python program that identifies numbers divisible by 3 or 5 within a given range, calculates their sum, and retrieves the last few elements from the list. It ensures valid input and provides a clear, efficient way to analyze numerical divisibility.

Modulo Magic

Modulo Magic is a Python application that finds numbers within a specified range that are divisible by any of a list of user-defined divisors. It also calculates the sum of these numbers and provides additional insights such as the last three numbers divisible by the given divisors.

Features

  • Find Divisible Numbers: Identifies numbers in a given range that are divisible by any of the user-specified divisors.
  • Sum Calculation: Computes the sum of all numbers that meet the divisibility criteria.
  • Last N Numbers: Returns the last few numbers that are divisible by the specified divisors.
  • Interrupt Handling: Gracefully handles program interruption (e.g., via Ctrl+C).

Installation

Ensure you have Python installed on your system. This project requires Python 3.6 or higher.

No additional packages are required.

Usage

Input Range

You will be prompted to enter the start and end of the range. Enter valid integers to specify the range.

Input Divisors

Enter the divisors one by one. Type done when you have finished entering all divisors.

View Results

The program will display:

  • The count of numbers divisible by the specified divisors.
  • The list of these numbers.
  • The last three numbers divisible by the divisors.
  • The sum of these numbers.

Exit the Program

You can exit the program anytime by pressing Ctrl+C.

Example

Please enter the start of the range: 10
Please enter the end of the range: 50
Enter the divisors (enter 'done' to finish):
Enter a divisor: 3
Enter a divisor: 5
Enter a divisor: done

In the range [10, 50], there are 18 numbers divisible by 3, 5.

These numbers are:
15, 18, 20, 21, 24, 25, 27, 30, 33, 35, 36, 39, 40, 42, 45, 48, 50

The last three numbers divisible by 3, 5 are: 36, 39, 40
The sum of all numbers divisible by 3, 5 in this range is: 663
