PyData Amsterdam 2019 was hosted last week by Booking.com in Amsterdam. The two days conference (plus one with workshops) allowed experts and users of data analytics tools to share their research, approaches, and mistakes. During the conference, one challenge was posted by GoDataDriven with a Lego Set as a prize. In this post, I present my approach to the problem which arrived fifth in the final classific (No Lego for me) but it reached that point with fewer requests compared to the other methods.
