# Calculate Sum of the First N Positive Integers

Write a small python program that reads a positive integer (N) from the user and then displays the sum of all of the integers from 1 to N. The sum of the first N positive integers can be computed using the formula: sum = (n)(n + 1)/2.

## #Calculate the sum of first N positive integers. ## #Read the input from the user n = int(input("Enter a positive integer: ")) #Calculate the sum total = n * (n+1) / 2 #Display the result print("The sum of the first",n,"positive integers",total)

###### Sample output of above program.

C:\>python C:\Python\programs\program1.py

Enter a positive integer: 10

The sum of the first 10 positive integers 55.0
