I made a date recommendation with the python for 2 users. One is based on the Euclidean distance and the other is based on the Pearson correlation. I used numpy and math function to do an array/vector calculations. One was a summation and the other was a Dot Product. If I run the code, the terminal collects the preferences of the exercises. If the users enter numbers from 0.0 to 5.0 then it would return the recommendation values. The Euclidean distance will give a number from 0.0 to 1.0 and the Pearson correlation will give a number from -1.0 to 1.0.
