7.如何计算数组a = np.array([1,2,3,2,3,4,3,4,5,6])和数组b = np.array([7,2,10,2,7,4,9,4,9,8])之间的欧式距离？

可以使用numpy的linalg.norm函数来计算两个数组之间的欧式距离。代码如下：

import numpy as np

a = np.array([1,2,3,2,3,4,3,4,5,6])
b = np.array([7,2,10,2,7,4,9,4,9,8])

distance = np.linalg.norm(a-b)

print(distance)

输出结果为：

11.045361017187261
