Strong number from n to m in python¶

In [7]:

n = int (input ('Enter the value of n: '))

m = int (input ('Enter the value of m: '))

​

if n > m:

    temp = n

    n = m

    m = temp

​

print ('Strong numbers from ', n, ' to', m, ' are:')

​

for x in range(n, m + 1):

    num = x

    summ = 0

    while num != 0:

        r = num % 10

        fact = 1

        for i in range (1, r + 1):

            fact = fact * i

        summ = summ + fact

        num = num//10

    if x == summ: 

        print (x, end = ', ')

Enter the value of n: 1000
Enter the value of m: 1
Strong numbers from  1  to 1000  are:
1, 2, 145,
