coord = list(polygons)[0]
coord.append(coord[0]) #repeat the first point to create a 'closed loop'
xs, ys = zip(*coord) #create lists of x and y values

plt.figure()
plt.fill(xs,ys,'k') 
plt.ylim(-5, 5)

but when I plot it I get only the half of the polygons. How can I get the other half? The real shape is in the following image:

CodePudding user response：

You have of list of lists in polygon. To create a single list from that you can use extend.

coord = []
for item in polygons:
    coord.extend(item)
coord.append(coord[0]) #repeat the first point to create a 'closed loop'
xs, ys = zip(*coord) #create lists of x and y values

plt.figure()
plt.fill(xs,ys,'k') 
plt.ylim(-5, 5)
plt.xlim(0, 10)
plt.show()
