Array is not iterable, but how to use as argument in zip()? - matplotlib

Question

I want to plot 3D visualizations of DICOM Scans, but I am stuck on this error.
I am using the marching cubes method. First from mesh verts and faces and returned then passed into plt_3d. Modules imported:
import numpy as np
import pydicom as pyd
import os
import matplotlib.pyplot as plt
from glob import glob
from mpl_toolkits.mplot3d.art3d import Poly3DCollection

imgs_after_resamp is the pixel array(3d) which contains the DICOM Data
def make_mesh(image, threshold=-300, step_size=1):
p = image.transpose(2,1,0)
verts, faces, norm, val = measure.marching_cubes_lewiner(p, threshold,
step_size=step_size, allow_degenerate=True)
print(verts)
return verts, faces
