如何用python中的topLeft点（0,0）和bottomRight点（1,1）两点初始化矩形类？

Question

I want to be able to create a rectangle where it has the data attribute of two points defining two opposite corners of a rectangle as, use the Points defined above, not using inheritance. But I am having trouble with the initialization method in the rectangle class and a few methods and not sure if I am going about this the correct way. I want the init : initialize with default p1 = (0,0), p2 = (1,1)

Here is what I have so far for the Point class:

import math

class Point:

    def __init__(self, x: float = 0.0, y: float = 0.0)->None:
        self.x = x # initialize to 0
        self.y = y # initialize to 0


    def moveIt(self, dx: float, dy: float)-> None:
        self.x = self.x + dx
        self.y = self.y + dy 

    def distance(self, otherPoint: float):
        if isinstance(otherPoint, Point):
            x1 = self.x
            y1 = self.y
            x2 = otherPoint.x
            y2 = otherPoint.y

            return ( (x1 - x2)**2 + (y1 - y2)**2 )**0.5

This all appears to work as expecte when I create a point.

p1 = Point()

print(p1.x, p1.y)

>>>> 0 0

But my Rectangle class is not working when I create a blank Rectangle object. Here is the code:

class Rectangle:
    def __init__(self, topLeft, bottomRight):
        self.topLeft = 0,0
        self.bottomRight = 1,1

I can't seem to find a way to have like I had it in the Point class where the Point is initialized from the get go to x=0, and y=0. Is there any way to do this in the Rectangle class? I tried the following but it wasn't allowed:

Class Rectangle:
    def __init__(self, topLeft = (0,0), bottomRight = (1,1)):
        self.topLeft = topLeft
        self.bottomRight = bottomRight

When I run the code I get errors that I cannot initialize like this.

r1 = Rectangle()

print(r1.topLeft, r1.bottomRight)

After the initialization I want to be able to pass in Points I made.

Finally, from this I am trying to create two methods Get_area to return the area of the rectangle as a floating point value and Get_perimeter to return the perimeter as a floating point value.

Answer 1

The problem is that you wrote Class instead of class . Your code works fine when it is rectified

You wrote

Class Rectangle:

You should write

class Rectangle:

Complete:

class Rectangle:
    def __init__(self, topLeft = (0,0), bottomRight = (1,1)):
        self.topLeft = topLeft
        self.bottomRight = bottomRight

r1 = Rectangle()
print(r1.topLeft, r1.bottomRight)    
> (0, 0) (1, 1)

Use the following way to override the default values

r1 = Rectangle(topLeft = (0,0.5), bottomRight = (1,1))

Edit 2: Overriding the defaults

p1 = (3,5) 
p2 = (6,10)
r1 = Rectangle() 
print (r1.topLeft, r1.bottomRight)
> (0, 0) (1, 1)

r2 = Rectangle(p1, p2)
print (r2.topLeft, r2.bottomRight)
> (3, 5) (6, 10)
