从Python 3.8开始，math模块直接提供dist函数，它返回两点之间的欧几里得距离(以元组或坐标列表的形式给出):

from math import dist

dist((1, 2, 6), (-2, 3, 2)) # 5.0990195135927845

如果你使用列表:

dist([1, 2, 6], [-2, 3, 2]) # 5.0990195135927845

import numpy as np
from scipy.spatial import distance
input_arr = np.array([[0,3,0],[2,0,0],[0,1,3],[0,1,2],[-1,0,1],[1,1,1]]) 
test_case = np.array([0,0,0])
dst=[]
for i in range(0,6):
    temp = distance.euclidean(test_case,input_arr[i])
    dst.append(temp)
print(dst)

这种解决问题方法的另一个例子:

def dist(x,y):   
    return numpy.sqrt(numpy.sum((x-y)**2))

a = numpy.array((xa,ya,za))
b = numpy.array((xb,yb,zb))
dist_a_b = dist(a,b)

首先求两个矩阵的差。然后，使用numpy的multiply命令应用元素乘法。然后，求元素与新矩阵相乘的和。最后，求求和的平方根。

def findEuclideanDistance(a, b):
    euclidean_distance = a - b
    euclidean_distance = np.sum(np.multiply(euclidean_distance, euclidean_distance))
    euclidean_distance = np.sqrt(euclidean_distance)
    return euclidean_distance

计算多维空间的欧氏距离:

 import math

 x = [1, 2, 6] 
 y = [-2, 3, 2]

 dist = math.sqrt(sum([(xi-yi)**2 for xi,yi in zip(x, y)]))
 5.0990195135927845

你可以减去向量，然后内积。

以你为榜样，

a = numpy.array((xa, ya, za))
b = numpy.array((xb, yb, zb))

tmp = a - b
sum_squared = numpy.dot(tmp.T, tmp)
result = numpy.sqrt(sum_squared)
