goal: Learn to write recursive functions with a base case. $($python$)$

Assignment: Write a function print$\_$tree that takes an int parameter. This parameter is the height of the tree to print. The tree's leaves should be asterisks and shaped as a triangle facing up$.$ At the base of the triangle, the tree should have a stem with a height of $1$ if the tree is less than $10$ high, and a height of $2$ otherwise, represented by the character $"]".$ If the height is not a positive number, it should print nothing.

You can at most use one other function to achieve this, which should be named $\_$print$\_$tree. You have to use recursion to complete this assignment.
