A function that returns smallest decimal number based on the input parameter

I want to have a function (def smallest_value(number):) that returns numbers like this:

    smallest_value(0) >> 1
    smallest_value(1) >> 0.1
    smallest_value(2) >> 0.01
    smallest_value(3) >> 0.001
    smallest_value(4) >> 0.0001

>Solution :

Try this one:

def smallest_value(number: int) -> float:
    return 10**(-number)
