100 Days of Code Day 15 - Python
Hello! My name is Rick and I am in search for gig as a developer :)
This past December I finished up a year long study with a full-stack school in NYC called Codeimmersives. We explored HTML, CSS, JavaScript, and how to build applications using the MERN stack. I learned about class-based components, passing props around (prop-drilling) and utilizing the component lifecycle(componentWillMount, componentDidMount, etc). After learning class based components, we moved on to functional based components using hooks, custom hooks, and different ways to manage state, such as the useContext and Redux APIs. (This is just a brief overview of the technologies I studied over the past year). Currently I am enrolled at devCodeCamp learning the basics of Python. I am documenting my journey by sharing these blog posts. Please help me out by dropping a comment below on what you think!
I spent my time refactoring the code I had written for this same problem yesterday. I'm still puzzled on why values repeat in the provide_random_item_from_list() function.
