python code to calculate euclidean distance from scratch code example

Example 1: euclidean distance python

# I hope to be of help and to have understood the request
from math import sqrt # import square root from the math module
# the x and y coordinates are the points on the Cartesian plane
pointA = (x, y) # first point
pointB = (x, y) # second point
distance = calc_distance(pointA, pointB) # here your beautiful result
def calc_distance(p1, p2): # simple function, I hope you are more comfortable
  return sqrt((p1[0]-p2[0])**2+(p1[1]-p2[1])**2) # Pythagorean theorem

Example 2: euclidean distance python 3 variables

# Python code to find Euclidean distance 
# using sum() and square() 
  
import numpy as np 
  
# intializing points in 
# numpy arrays 
point1 = np.array((1, 2, 3)) 
point2 = np.array((1, 1, 1)) 
  
# finding sum of squares 
sum_sq = np.sum(np.square(point1 - point2)) 
  
# Doing squareroot and 
# printing Euclidean distance 
print(np.sqrt(sum_sq))
