Answer 1

this is better Imadez

num = int( input() )

while num > 9:
dig = sum( int( c ) for c in str( num ) )
num = dig
print( num )

Answer 2

Just like this:

num = int( input() )

while num > 9:
num = sum( int( c ) for c in str( num ) )
print( num )

Answer 3

Harsha S ,

there is no need to use a while loop. have a look at this, it is based on your code:

num = input()
print(sum( int( c ) for c in num))

Answer 4

Harsha S ,

ok, i understand. under this circumstance the loop is needed.

Answer 6

Harsha S How about this one? :-

(Edited)

print((k := lambda x: x if x < 10 else k(sum(int(i) for i in str(x))))(int(input())))

# Hope this helps

Answer 7

You can remove line 10: "num = dig"

Answer 8

Lothar read the docstring
I need the input to be reduced to a single digit

Answer 9

Calvin Thomas

This is more precise
print((k := lambda x: x if x < 10 else k(sum(int(i) for i in str(x))))(int(input())))

Answer 10

it doesn't work

Answer 11

yeah it works tq

Answer 12

Harsha S Oh, I just forgot to cast the input into an integer. Thank you for the correction.
