代码如下:
import random
n1=random.randrange(1,10)
num2=random.randrange(1,10)
print(n1)
print(num2)

class PointLenth:
def init(self,x1,y1,x2,y2):
self.x1=x1
self.x2=x2
self.y1=y1
self.y2=y2
def lenth(self):
dx=(self.x1)-(self.x2)
dy=(self.y1)-(self.y2)
distance=(dx2+dy2)**0.5
print(distance)

p1=PointLenth(n1,11,num2,21)
print(p1.lenth())
运行结果截图:
