Linear Regression in Python; Predict The Bay Area's Home Prices

I chose the Bay Area housing price dataset that was sourced from Bay Area Home Sales Database and Zillow. This dataset was based on the homes sold between January 2013 and December 2015. It has many characteristics of learning. The dataset can be downloaded from here. There are several features that we do not need, such as "info", "z_address", "zipcode"(We have "neighborhood" as a location variable), "zipid" and "zestimate"(This is the price estimated by Zillow, we don't want our model to be affected by this).
