Check for Armstrong number in a range
In our last post (‘Check if a Number is Armstrong‘) we wrote a codes to check a given number and see whether it is an Armstrong or Not.
Today, we want to go through a set of numbers and see how many Armstrong numbers are there.
Before calling the ‘armstrong_in_range()’ and just to keep the code as less as we can, I assume the two numbers has the same number of digits, also I am getting the power (p) and the range numbers (n1, n2) out-side of this function and passing all as variables.
def armstrong_in_range(p,n1,n2):
my_sum = 0
count = 0
for num in range (n1,n2):
tot=num
for arm in range(p):
my_sum = my_sum + ((num % 10)**p)
num = num // 10
if my_sum == tot:
print(‘\nThe number {} is Armstrong.’.format(tot))
my_sum=0
count = count +1
else:
my_sum=0
print(‘\nWe have {} armstrong number(s)’.format(count))
