Counting number of digits of input using python

Question

I am trying to count the number of digits of an input. However, whenever I input 10 or 11 or any two digit number, the output is 325.

Answer 1

The reason is that in python 3 the division of two integers yields a floating point number. It can be fixed using the // operator:

number = int(input())
digits_count = 0
while number > 0:
    digits_count += 1
    number = number // 10
