Python Sum of Series 1/1 + 1/2 + … + 1/N Program
This program helps you to learn the fundamental structure and syntax of Python programming.
# Program to compute sum of series 1/1 + 1/2 + ... + 1/N
n = int(input("Enter a positive integer N: "))
if n <= 0:
print("Please enter a positive integer.")
else:
total = 0.0
for i in range(1, n + 1):
total += 1 / i
print(f"Sum of series up to 1/{n} is {total}")Output
Enter a positive integer N: 5 Sum of series up to 1/5 is 2.283333333333333
Understanding Sum of Series 1/1 + 1/2 + … + 1/N
We add each reciprocal 1/i in a loop from 1 to N, accumulating the sum in a float.
