Creating a model class for classification tasks using the nearest neighbor algorithm. We have created a machine learning method that does not make use of sklearn.

We have data from the website of a real estate agency. The target variable is air conditioner: apartment has air conditioner-(1); no air conditioner-(0). We have created a class NearestNeighborClassificator which contains methods fit() and predict(). fit() stores the entire training set while predict() uses the nearest_neighbor_predict() function to predict the value.
