[已解决]TypeError: 'float' object is not callable

指尖、行

以下这段代码运行后出现 TypeError: 'float' object is not callable
求助

import math as m
import random as r

class Point:
    def __init__(self):
        self.x = r.randint(0, 100)
        self.y = r.randint(0, 100)
        print('该点的x坐标为：%d\n该点的y坐标为：%d' % (self.x, self.y))
    def self_x(self):
        return self.x
   
    def self_y(self):
        return self.y

class Line:
    def __init__(self, PointA, PointB):
  #      PointA = Point()
    #    PointB = Point()
        self.line_x = PointA.self_x() - PointB.self_x()
        self.line_y = PointA.self_y() - PointB.self_y()
        self.length = m.sqrt(self.line_x *self.line_x  + self.line_y*self.line_y)

    def length(self):
        return self.length

变量名跟方法名冲突了，如下修改即可：

1. import math as m
   
2. import random as r
   
3. 
   
4. class Point:
   
5.     def __init__(self):
   
6.         self.x = r.randint(0, 100)
   
7.         self.y = r.randint(0, 100)
   
8.         print('该点的x坐标为：%d\n该点的y坐标为：%d' % (self.x, self.y))
   
9.     def self_x(self):
   
10.         return self.x
    
11.    
    
12.     def self_y(self):
    
13.         return self.y
    
14. 
    
15. class Line:
    
16.     def __init__(self):
    
17.         PointA = Point()
    
18.         PointB = Point()
    
19.         self.line_x = PointA.self_x() - PointB.self_x()
    
20.         self.line_y = PointA.self_y() - PointB.self_y()
    
21.         self.length = m.sqrt(self.line_x *self.line_x  + self.line_y*self.line_y)
    
22. 
    
23.     def getLength(self):
    
24.         return self.length

谢谢 小甲鱼 ，今天学习了lesson 39就明白了：当方法名和属性名一样的时候，属性名会覆盖方法名。Yeah!
