- Write a blog post about everything you just learned / this project is covering. Your blog post should be articulated this way (one paragraph per item):
- Write a function magic_string() that returns a string “Holberton” n times the number of the iteration (see code):
- Write a class LockedClass with no class or object attribute, that prevents the user from dynamically creating new instance attributes, except if the new instance attribute is called first_name.
