numpy extract xyz points from 3 lists-CodePudding

I have 3 lists

x = [1,2,3,4,5,6]
y = [1,2,3,4,5,6]
z = [1,2,3,4,5,6]

Now I would like to extract the points. So that the final array would look like :

points = [[1,1,1], [2,2,2] ... ]

Is there an easy way to do it using numpy, than using the for loop?

CodePudding user response：

You can use zip and list:

points = list(zip(x,y,z))

You can also transpose a numpy array:

points = np.array([x,y,z]).T

And, you can stack them on dimensions you choose:

points = np.stack([x,y,z], 1)

CodePudding user response：

since my first guess with matrix turned out to be wrong, you just have to use a 2-dimensional array:

import numpy as np
a = np.array([x,y,z])
a[:,0]
