Jan 15, 2017 · Simpler way to extract last two digits of the number (less efficient) is to convert the number to str and slice the last two digits of the number. For example: return int(str(num)[-last_digits_count:]) # ^ convert the number back to `int`

Use the modulo operator to get the last two digits of the number. Extract the last digit using modulo 10. Extract the second last digit by performing integer division by 10. Sum the two extracted digits. Let's break down the algorithm: Compute last_two_digits = n …

Feb 24, 2025 · The task is to write a Python program to add the first and last digits of the given number N. Examples: Input: N = 1247 Output: 8 Explanation: First digit is 1 and Last digit is 7. So, addition of these two (1 + 7) is equal to 8.Input: N = 73

Jul 30, 2018 · Python has a few ways to do it. The same Format String Syntax is used by the format function, the str.format method, Formatter subclasses, and (with slight differences that aren't relevant here) f-string literals. You can specify a width of 2, plus an align of = (meaning numeric alignment—padding is placed after any + or -) and a fill of 0.

May 18, 2023 · The task is to write a Python program to add the first and last digits of the given number N. Examples: Explanation: First digit is 1 and Last digit is 7. So, addition of these two (1 + 7) is equal to 8. Take input in the form of String or typecast given input in String.

If you want to keep summing the digits until you get a single-digit number (one of my favorite characteristics of numbers divisible by 9) you can do: def digital_root(n): x = sum(int(digit) for digit in str(n)) if x < 10: return x else: return digital_root(x)

Aug 25, 2024 · Here, I will explain different methods to calculate the sum of digits of a number in Python with examples. To calculate the sum of digits of a number in Python using a while loop, you can repeatedly extract the last digit of the number using the modulus operator (% 10) and add it to a running total.

Dec 27, 2024 · Sum of number digits in list involves iterating through each number in the list, breaking the number into its individual digits and summing those digits. The simplest way to do is by using a loop. This method manually extracts digits using a while loop. Explanation:

Oct 31, 2024 · Run the script to find the sum of digits for the specified number. 🧠 How the Program Works. The program defines a function sum_of_digits that takes an integer number as input and returns the sum of its digits. Inside the function, it uses a …

Learn how to add two numbers in Python. Use the + operator to add two numbers: In this example, the user must input two numbers. Then we print the sum by calculating (adding) the two numbers:
