reset_index() will give you index numbers for each row of your data frame. This allows for easy access and retrieval of specific rows in your data frame. Click here for more information on reset_index().

@Caealana do I need to reset_index() if I do not need the indices? This seems like unneeded processing time (as minimal as it may be).

Generally, it is good practice to, as you may need use of that particular data frame in the future for applications that require the indices. If you're sure you won't ever need the indices for any possible applications in the future, you can leave it out.

You have great questions! I apologize, but could you refrain from commenting until I finish going over your code? I will mark your project as reviewed once I have finished grading it.
