Python 实现两个矩形重合面积

import math
x1, y1, x2, y2 = input().split(" ")
x1, y1, x2, y2=int(x1), int(y1), int(x2), int(y2)
# print(x1, y1, x2, y2)
x1,x2 = min(x1,x2),max(x1,x2)
y1,y2= min(y1,y2),max(y1,y2)

# print(x1, y1, x2, y2)

x3, y3, x4, y4 = input().split(" ")
x3, y3, x4, y4 = int(x3), int(y3), int(x4), int(y4)
x3,x4 = min(x3,x4),max(x3,x4)
y3,y4 = min(y3,y4),max(y3,y4)

# print(x3, y3, x4, y4)

if (x2<=x3 or x4<=x1) and (y2 <= y3 or y4<=y1):
    print(0)
else:
    lens = min(x2, x4) - max(x1, x3)
    wide = min(y2, y4) - max(y1, y3)
    print(lens*wide)
