Numpy also comes built-in with a function that allows you to calculate the dot product between two vectors, aptly named the dot() function. Use Dot to Find the Distance Between Two Points in Python Print(numpy_euclidian_distance_short(point_1, point_2))Д«efore we continue with other libraries, letвЂ™s see how we can use another numpy method to calculate the Euclidian distance between two points. Return np.sqrt(np.sum(np.square(np.array(point_1) - np.array(point_2)))) If you wanted to use this method, but shorten the function significantly, you could also write: import numpy as npДef numpy_euclidian_distance_short(point_1, point_2):

We then took the square root of this sum and returned it.

We calculated the sum of the squares between the differences for each axis.

We then turned both the points into numpy arrays.

We then created a function numpy_euclidian_distance() which takes two points as parameters.

We imported numpy and declared our two points.

LetвЂ™s take a look at what weвЂ™ve done here: Print(numpy_euclidian_distance(point_1, point_2)) Squared_distance = np.sum(np.square(array_1 - array_2)) LetвЂ™s see how: # Python Euclidian Distance using Sum and ProductДef numpy_euclidian_distance(point_1, point_2):ДЄrray_1, array_2 = np.array(point_1), np.array(point_2) We can easily use numpyвЂ™s built-in functions to recreate the formula for the Euclidian distance.

Keep in mind, itвЂ™s not always ideal to refactor your code to the shortest possible implementation. We were able to cut down out function to just a single return statement. Return sum( - point2) ** 2 for x in range(len(point1))]) ** 0.5 We can dramatically cut down the code used for this, as it was extremely verbose for the point of explaining how this can be calculated: # Python Euclidian Distance using Naive Method Finally, we return the square root of this sum.

We then square these differences and add them up.Iterate over each points coordinates and find the differences.Print(naive_euclidian_distance(point_1, point_2)) Sum_of_squares = sum(differences_squared) Say we have two points, located at (1,2) and (4,7), letвЂ™s take a look at how we can calculate the euclidian distance: # Python Euclidian Distance using Naive MethodДef naive_euclidian_distance(point1, point2):Дifferences = - point2 for x in range(len(point1))]Дifferences_squared = Find the Euclidian Distance between Two Points in Python using Sum and SquareДЄ very intuitive way to use Python to find the distance between two points, or the euclidian distance, is to use the built-in sum() and product() functions in Python. To learn more about the Euclidian distance, check out this helpful Wikipedia article on it. Because of this, understanding different easy ways to calculate the distance between two points in Python is a helpful (and often necessary) skill to understand and learn. For example, they are used extensively in the k-nearest neighbour classification systems. We can easily calculate the distance of points of more than two dimensions by simply finding the difference between the two pointsвЂ™ dimensions, squared.Д®uclidian distances have many uses, in particular in machine learning. Because of this, it represents the Pythagorean Distance between two points, which is calculated using: The Euclidian Distance represents the shortest distance between two points.
