Program:
a=int(input("Enter a number: "))
sum = 0
while(a > 0):
sum=sum+a
a=a-1
print("The sum of natural numbers is",sum)
Output:
Enter a number: 5
The sum of natural numbers is 15
Python program to print sum of n natural numbers video:
def decitobin(n): if n > 1: decitobin(n // 2) print(n % 2,end='') num = int(input("Enter any decimal number: ")) decitobin(num) Output: Enter any decimal number: 42 > 101010>
Program: n = int(input("Enter Positive Number : ")) sum = 0 sum= ((n*n)*(n+1)*(n+1))/4 print("The Sum of Series is",sum) Output: Enter Positive Number : 2 The Sum of Series is 9.0
The mathematical formula to find the sum of 1²+2²+3²+….+n² is n(n+1)(2n+1)/6 So to find the sum of series we use this formula. Program: n = int(input("Enter Positive Number : ")) sum = 0 sum= (n*(n+
