Path to data science with R and Python

I am on my path to data science with both R and Python, I started as a self-taught but then I soon realized I needed some structure. I have purchased a couple of data science classes at Udemy which were very helpful tutorials, but as a beginner that wasn’t enough. I wanted an equal amount of hands-on practice with the course. Some few courses include assignments to practice by yourself but you have to search and review each course yourself to find out if they include assignment or project, other than what the instructor use for their tutorials. I’m currently searching for an affordable course path.
