Oignon convex hull

[Scientifix]

Here is my new code :
Oups,made a mistake with the code ... I don't know how to edit :(
Can you explain me my mistake ?
Thanks a lot,
Scientifix

Here is the correct one :

from scipy.spatial import ConvexHull
import matplotlib.pyplot as plt
import numpy as np

points = np.random.rand(30, 2)

Plot = True

def min_convex(points):
 
    oignon_layers = []    
 
    while len(points) > 4:
        layer = ConvexHull(points)
        oignon_layers.append(layer)
        points =  points = np.delete(points, layer.vertices, axis=0)
 
    if Plot == True:
          plt.plot(points[:,0], points[:,1], 'o')
          for layer in oignon_layers:
              for simplex in layer.simplices:
                 plt.plot(points[simplex, 0], points[simplex, 1], 'k-')  
    plt.show()

with the error:

Error:
plt.plot(points[simplex, 0], points[simplex, 1],'k-')  
IndexError: index 24 is out of bounds for axis 0 with size 4
