We have prepared a set of Editor's Choice Solutions.
You will see them first after you solve the mission. In order to see all other solutions you should change the filter.

You are given a positive number. Your function should calculate the product of the digits excluding any zeroes.
For example: The number given is 123405. The result will be 1*2*3*4*5=120 (don't forget to exclude zeroes).
Input: A positive integer (int).
Output: The product of the digits as an integer (int).
Examples:
assert checkio(123405) == 120 assert checkio(999) == 729 assert checkio(1000) == 1 assert checkio(1111) == 1
How it is used: This task can teach you how to solve a problem with simple data type conversion.
Precondition:
- 0 < number < 106
