Armstrong Number documentation and code is incorrect

[Dentyr]

Description

As stated in Wikipedia, including other sources: (https://en.wikipedia.org/wiki/Narcissistic_number) "In number theory, a narcissistic number (also known as a pluperfect digital invariant, an Armstrong number, or a plus perfect number) in a given number base b is a number that is the sum of its own digits each raised to the power of the number of digits."

Meanwhile, in the current documentation: "Armstrong number is a number that is equal to the sum of cubes of its digits."

So in the python script, it says, while temp > 0: digit = temp % 10 sum += digit ** 3 temp //= 10

For Armstrong numbers which have 3 digits, this will be correct. However, for any other Armstrong numbers, like 1634, the program will incorrectly say that it is not an Armstrong number.
