Python中的调用函数 [英] Python call function within class

问题描述

我有这个代码，计算两个坐标之间的距离。这两个函数都在同一个类中。

但是如何调用函数 distToPoint code> isNear ？

  def distToPoint（self，p）：
 
使用pythagoras找到距离
（a ^ 2 = b ^ 2 + c ^ 2）

 ... 
 $ b b def isNear（self，p）：
 distToPoint（self，p）
 ... 
  

self 。

  def isNear（self，p）：
 self.distToPoint（p）
 ... 
  

I have this code which calculates the distance between two coordinates. The two functions are both within the same class.

However how do I call the function distToPoint in the function isNear?

def distToPoint(self, p):
    """
    Use pythagoras to find distance
    (a^2 = b^2 + c^2)
    """
    ...

def isNear(self, p):
    distToPoint(self, p)
    ...

解决方案

Since these are member functions, call it as a member function on the instance, self.

def isNear(self, p):
    self.distToPoint(p)
    ...
