Armstrong number is a number that is equal to the sum of cubes of its digits. For example 0, 1, 153, 370, 371 and 407 are the Armstrong numbers.
Program:
n = int(input("Enter a number: "))
sum = 0
a = n
while n > 0:
digit = n % 10
sum += digit ** 3
n //= 10
if a == sum:
print("Armstrong number")
else:
print("Not Armstrong number")
Output:
Enter a number: 153 Armstrong number

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+
