# Python code to find Euclidean distance
# using dot() and sqrt() methods
# Import NumPy Library
import numpy as np
# initializing points in
# numpy arrays
point1 = np.array((4, 4, 2))
point2 = np.array((1, 2, 1))
# subtracting both the vectors
temp = point1 - point2
# Perform dot product
# and do the square root
dist = np.sqrt(np.dot(temp.T, temp))
# printing Euclidean distance
print(dist)
