Hi, there is a bug in your code. Inside “dist” function you are doing np.sqrt(sum(x1-x2)**2). But it should be np.sqrt(sum((x1-x2)**2)) , as first we have to square the difference and then sum those (x1-x2)**2 terms. In your code you are first performing summation of (x1-x2) and then squaring the term.
