Please anyone find my code error

Question

i=int(input("enter number "))
sum=0
a=i
while (i>0):
sum=sum+(i%10)*(i%10)*(i%10)
i//10
if a==sum:
print("this is a armstong no")
else:
print("number is not Armstrong no")

Answer 1

Sachin Patel ,

the calculation of an armstrong number is not as it should be. the short definition of what an armstrong number is:

> an armstrong number is an integer such that the sum of the cubes of its digits is equal to the number itself. <

[EDITED]
to calculate the armstrong number we need these steps: ( using 407 as a sample which is an armstrong number)

(1) separate the digits of the number 407
4
0
7

(2) take each of the digit an calculate:
4 > 4**3 = 64
0 > 0**3 = 0
7 > 7**3 = 343
------------------------
sum: 407

Answer 2

Can you explain what an armstrong number is?

Answer 3

I think you want your if statement out of the while loop, right?
So you'd need to change the indentation.

You could also possibly write the sum line like this:
sum += (i%10)*...

Answer 4

I've played around with the code. You also have an infinite loop because of your i//10 line.
