如何在python中繪製矩形？

Question

我有4個點，想用它來繪製矩形

a=[0,0] 
    b=[0,5] 
    c=[7,0] 
    d=[7,5] 

有沒有辦法使用matplotlib或seaborn繪製矩形？

從http://matthiaseisen.com/pp/patterns/p0203/：

a=[0,0] 
b=[0,5] 
c=[7,0] 
d=[7,5] 
width = c[0] - a[0] 
height = d[1] - a[1] 
lims = (0, 10) 

import matplotlib.pyplot as plt 
import matplotlib.patches as patches 
%matplotlib inline 

fig1 = plt.figure() 
ax1 = fig1.add_subplot(111, aspect='equal') 
ax1.add_patch(
    patches.Rectangle((0, 0), width, height)) 
plt.ylim(lims) 
plt.xlim(lims)
