You now know that it is posible to call a Python function from somewhere of your code, however a function can call itself and this is known as recursión.
The goal of this project is to make a program that calculates the factorial of a number by using recursion.
Nota: It is important that you understand what is recursion, because it might come helpful while you are using it at your project.
1. Recursion
2. Documentation
3. Functions
Go to your project directory and execute nosetests on the terminal. The code should work perfectly.
