Can you sum numbers in a while loop in Python?
While loop to calculate sum and average Run a while loop till n is greater than zero. In each iteration, add the current value of n to the sum variable and decrement n by 1. Calculates the average by dividing the sum by n (total numbers).
How do you find the sum of n numbers in a for loop?
Using the Mathematical Formula
- #include
- int main()
- {
- int n = 40; // declare & initialize local variable n.
- int sum = (n * (n + 1) ) / 2; /* define the mathematical formula to calculate the sum of given number. */
- printf(“Sum of %d natural number is = %d”, n, sum); // print the sum of natural number.
- return 0;
- }
How do you add a sum in a while loop?
Simple use if statement with a while loop to calculate the Sum of n numbers in Python. Taken a number input from the user and stored it in a variable num. Use a while loop to iterate until num gets zero. In every iteration, add the num to sum, and the value of num is decreased by 1.
