Answer to Question #247427 in Python for Isabel Cortez

Question

3. The Last 'Zeroes'

How many zeroes are there after the last non-zero digit of a million? A trillion? To easily identify that, let us make a program to count and print the number of zeroes after the last non-zero digit on a number. For example, in 20400, there are 2 zeroes after the last non-zero digit of the number, 4.

Are you up for this challenge?

Input

A line containing an integer.

20400

Output

A line containing an integer.

2

Answer 1

def last_zeros(num):
        new_num = str(num)
        count = len(new_num) - len(new_num.rstrip("0"))
        return count


N=int(input("Enter an interger: "))
print(last_zeros(N))
