To print Strong Numbers, let's first look at the definition of it. It is a number that is the sum of factorials of its own digits. For example, 145 is a Strong number. First, create a function to calculate factorial:
def fact(num): def factorial(n): num = 1 while n >= 1: num = num * n n = n - 1 return num
You can print these numbers by running the following code:
def factorial(n): num = 1 while n >= 1: num = num * n n = n - 1 return num def print_strong_nums(start, end): for i in range(start, end + 1): # Get the digits from the number in a list: digits = list(map(int, str(i))) total = 0 for d in digits: total += factorial(d) if total == i: print(i) print_strong_nums(1, 380)
This will give the output:
1 2 145
