Today, I was extremely frustrated with codecademy. One of the best things about learning Machine learning and other languages in this amazing platform is how much background info it provides to the user and helps understand the algorithm before writing the piece of code. While doing this lesson on Classification: K-Nearest Neighbors, I was recreating the same code om my own system as well, so that I can follow through on my system and help me build the logic, but the files required were missing. Why maintain that much of secrecy? I did some courses on pandas, and the files required were available on the navigator which I could copy, paste, and use it on my system. I tried so many things to get those files and scripts required like used glob module and with open file and like that, but of no avail. I would be very grateful what other users think about that and would be great if anyone from the codecademy responds. Thanks.
