I'm trying to make a map of the Netherlands where the provinces are filled with some color. I've been looking to this SO post and this blog post for help and code examples. Except where they use

lines = LineCollection(shpsegs,antialiaseds=(1,))
lines.set_facecolors(cm.jet(np.random.rand(1)))

to fill up the shapes with a given color, this just doesn't do anything for me. I can't figure out why it's not doing anything for me. It's not giving me an error, and I also don't see any color in the shape.

I would really appreciate some help. My (almost) entire code is below, I trimmed off some unnecessary bits:

import shapefile
import matplotlib.pyplot as plt
import matplotlib as mpl
from matplotlib.collections import LineCollection
import numpy as np


##Importing shapefile and records
sf = shapefile.Reader("NLadmin/NLD_adm1")

records = sf.records()
for i in range(len(records)):
 print(str(i) + " - " + str(records[i][4]))

shapes = sf.shapes()
for i in range(len(shapes)):
 print(shapes[i].parts)


##Figure
fig = plt.figure()
ax = plt.axes()
ax.set_aspect(1.1541)
ax.set_xlim(3, 7.5)
ax.set_ylim(50.5, 54)

print("-------")

##Use the shapes and records
for shape, record in zip(list(sf.iterShapes()), records):
 number_points = len(shape.points)
 number_parts = len(shape.parts)

 for index in range(number_parts):
 startindex = shape.parts[index]

 if index < len(shape.parts)-1:
 endindex = shape.parts[index+1]
 else: 
 endindex = number_points

 shapesegment = shape.points[startindex:endindex]

 x_lon = []
 y_lat = []
 for index in range(len(shapesegment)):
 x_lon.append(shapesegment[index][0])
 y_lat.append(shapesegment[index][1])


 linelist = []
 for i in range(len(x_lon)):
 intermediatelist = []

 try:
 startxy = (x_lon[i], y_lat[i])
 endxy = (x_lon[i+1], y_lat[i+1])
 except:
 continue 

 intermediatelist.append(startxy)
 intermediatelist.append(endxy)
 linelist.append(intermediatelist)


 lines = LineCollection(linelist,antialiaseds=(1,))
 lines.set_facecolors('#e41a1c')
 lines.set_edgecolors('k')
 lines.set_linewidth(1)

 ax.add_collection(lines)


plt.show()
