Python Program to find Number Combination

πŸ™‹ Introduction

In the realm of programming, creating combinations of numbers is a common and useful task. A combination is a selection of items from a collection, where the order of selection does not matter.

In this tutorial, we'll explore a Python program that generates combinations of two specified numbers within a given range.

πŸ“„ Example

Let's take a look at the Python code that achieves this functionality.

generate_combinations.py
Copied
Copy To Clipboard
def count_digits(num):
    count = 0
    while num != 0:
        num //= 10
        count += 1
    return count

def generate_combinations(number1, number2, limit):
    print(f"List of combinations of {number1} and {number2} up to {limit}:")

    for i in range(1, limit + 1):
        current_number = i

        # Check if the current number contains only the specified digits
        while current_number > 0:
            digit = current_number % 10
            if digit != number1 and digit != number2:
                break
            current_number //= 10

        # If the current number contains only the specified digits, print it
        if current_number == 0:
            print(i, end=" ")

    print()

# Replace these values with your desired numbers and limit
target_number1 = 4
target_number2 = 8
combination_limit = 500

# Call the function to generate combinations
generate_combinations(target_number1, target_number2, combination_limit)

πŸ’» Testing the Program

To test the program with different values, replace the values of target_number1, target_number2, and combination_limit in the code.

Output
List of combinations of 4 and 8 up to 500:
4 8 44 48 84 88 444 448 484 488

Run the script to see the list of combinations.

🧠 How the Program Works

  1. The program defines a function count_digits to calculate the number of digits in a given number.
  2. The function generate_combinations generates combinations of two specified numbers up to a given limit.
  3. Inside the function, it iterates through numbers from 1 to the specified limit.
  4. For each iteration, it checks if the current number contains only the specified digits.
  5. If the condition is met, the current number is a combination, and it is printed.

🧐 Understanding the Concept of Number Combination

Before delving into the code, let's take a moment to understand the concept of combinations. In mathematics, a combination is a selection of items from a collection, where the order of selection does not matter.

For example, consider the specified numbers as 4 and 8. The combinations of 4 and 8 up to 500 include 4, 8, 44, 48, 84, 88, 444, 448, 484, and 488.

🎒 Optimizing the Program

While the provided program is effective, you can explore and implement optimizations based on specific requirements or constraints.

Feel free to incorporate and modify this code as needed for your specific use case. Happy coding!
