1# Program to print Armstrong numbers in a range
2

3start = int(input("Enter start of range: "))
4end = int(input("Enter end of range: "))
5

6for num in range(start, end + 1):
7    digits = str(num)
8    power = len(digits)
9    total = 0
10    for d in digits:
11        total += int(d) ** power
12    if total == num:
13        print(num)

Output

Enter start of range: 1
Enter end of range: 500
1
153
370
371
407

What's going on

We extend the Armstrong number logic to every number in the range and print those that satisfy the condition.
