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?

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

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

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

That doesn't work because distToPoint is inside your class, so you need to prefix it with the classname if you want to refer to it, like this: classname.distToPoint(self, p). You shouldn't do it like that, though. A better way to do it is to refer to the method directly through the class instance (which is the first argument of a class method), like so: self.distToPoint(p).
