Narcissistic decimal number

A Narcissistic decimal number is a positice decimal number, $n$ in which if there are $m$ digits in the sumber then the sum of all the individual digits of the number raised to the power $m$ is equal to $n$.

Narcissistic decimal number is a draft programming task. It is not yet considered ready to be promoted as a complete task, for reasons that should be found in its talk page.

For example, if $n$ is 153 then $m$, the number of digits is 3 and we have $1^{3}+5^{3}+3^{3}=1+125+27=153$ and so 153 is a narcissistic decimal number.

The task is to generate and show here, the first 25 narcissistic numbers.

Python

This solution pre-computes the powers once.

<lang python>from __future__ import print_function from itertools import count, islice

def narcissists():

   for digits in count(0):
       digitpowers = [i**digits for i in range(10)]
       for n in range(int(10**(digits-1)), 10**digits):
           div, digitpsum = n, 0
           while div:
               div, mod = divmod(div, 10)
               digitpsum += digitpowers[mod]
           if n == digitpsum:
               yield n

for i, n in enumerate(islice(narcissists(), 25), 1):

   print(n, end=' ')
   if i % 5 == 0: print() 

print()</lang>

Output:

0 1 2 3 4 
5 6 7 8 9 
153 370 371 407 1634
