Why does this code give no output?

Question

I need to find the sum of the digits in a number.

n = int(input())

total = 0

while n > 0:
n%10
total = n + n

print(total)

Answer 1

James Murphy ,

the program needs to have 2 divudions:

▪︎modulo division '%'
▪︎floor division '//'

n = int(input())
total = 0

while n > 0:
digit = n % 10
total += digit
n = n // 10

print(total)

Answer 2

James Murphy, I figured it out.
Sololearn doesn't output when it knows that there is an infinite loop... the print statement is after the infinite loop, thus it'll never print.

Answer 3

Maybe do: n = n % 10

Answer 4

That doesn't seem to help, still no output.

Answer 5

James Murphy, if there is no output, the problem is not in code.. you should have an output because you have a print inside a global scope.

Check the area you are working with

Answer 6

Its within a sololearn activity on my phone app so not a lot I can do about the area

Answer 7

OK, thanks. How do I make it not be an infinite loop?

Answer 8

James Murphy, I don't know what's your need, but I can explain why you get an infinite loop:

- Assume you enter 1 as input.
n = n % 10 -> n = 1
n = n % 10 -> n = 1
n = n % 10 -> n = 1
....

Answer 9

OK thanks, that makes sense, I'll have a fiddle with it.

Answer 10

Thanks very much, I can see that the floor division is needed to make n no longer be greater than 0, thus breaking the while loop. (I think)

Answer 11

i don't understand this

Guess the output of this code:

things = [”text", 0, [1, 2, 8], 4.56]
print(things[2][2])

Answer 12

It would be 8 right?

Answer 13

n=int(input("Enter your number="))
s=0
a=n
while n>0:
t=n%10
s=s+t
n=n//10
print("\nSum of digit %i is =%i"%(a,s))
