Question
Write a Python program to calculate the sum of the series: 1 + 2 + 3 + … + n. e.g.:Input: 5Output: 15CODE EDITORCONSOLE12345678n = input()def series_sum(num): print(series_sum(n))
Solution
Sure, here is the corrected Python program to calculate the sum of the series: 1 + 2 + 3 + … + n.
def series_sum(n):
return sum(range(1, n+1))
n = int(input("Enter a number: "))
print(series_sum(n))
In this program, we first define a function series_sum(n) that calculates the sum of the series from 1 to n using the built-in sum() function and range() function. Then we ask the user to input a number, convert it to an integer using int(), and pass it to the series_sum() function. The result is then printed out.
