-This module contains a function that deals with checking if a number is positive.
-The function will take an integer as an input and returns a boolean value indicating
-whether the number is greater than zero.
-
-Function:
-- is positive(number: int) -> bool
-
-
-Exceptions:
--Raises TypeError if the input is not an integer.
-
-
-For Example:
->>> is_positive(5)
-True
->>> is_positive(-3)
-False
->>> is_positive(0)
-False
