How to draw polygons with Python?

Question

I have input values of x, y coordinates in the following format:

[[1,1], [2,1], [2,2], [1,2], [0.5,1.5]]

I want to draw polygons, but I don\'t

Answer 1

All the other answers seems veryhigh level, I guess that is my impression as a mechanical engineer. Here's a simple version of the code:

from numpy import *
from matplotlib.pyplot import *
x = ([1,2,2,1,0.5,1]) 
y = ([1,1,2,2,1.5,1])
plot(x,y)
show()
