Fir tree
Created on Jan. 9, 2018 by Julien Palard
You'll write a Python 3 program drawing a fir tree.
The size of the drawed fir tree will depend on the single parameter given to your program. As always, print a human error message if no parameter are given to your program.
Given 0, your program should display nothing.
Advice
You can test is for several values of the parameter here:

etc...
Here is what it should look like:
$ for i in $(seq 5); do python3 solution.py $i; done
