We expect answers to be supported by facts, references, or expertise, but this question will likely solicit debate, arguments, polling, or extended discussion. Thank you! The Euclidean distance between any two points, whether the points are in a plane or 3-dimensional space, measures the length of a segment connecting the two locations. The two points must have the same dimension. The Euclidean distance between two points in either the plane or 3-dimensional space measures the length of a segment connecting the two points. Write a Python program to compute the distance between the points (x1, y1) and (x2, y2). For efficiency reasons, the euclidean distance between a pair of row vector x and y is computed as: dist (x, y) = sqrt (dot (x, x)-2 * dot (x, y) + dot (y, y)) This formulation has two advantages over other ways of computing distances.
