Python Program to Find Sum of N Natural Numbers using For loop
Initially, we read the input number from the user. Then iterate over a for loop to calculate the total sum and print the value.
Source code:
# Python program to find sum of n natural numbers
# input number
num = int(input('Enter a number: '))
# find sum of natural number
sum = 0
for x in range (1, num+1):
sum += x
# print result
print('The sum of natural number =', sum)Output:
Enter a number: 4 The sum of natural number = 10
