[PYTHON]Help adding two 3d vectors in a class?

My code is included. Can you alter the function add, and make it so it can add two vectors together and return a new vector sum of the two? Thanks

code:

from math import *

class Vector:
x = 0
y = 0
z = 0

def __init__(self,x,y,z):
self.x = float(0)
self.y = float(0)
self.z = float(0)

def __str__(self):
s = str('vec3d: ' + str(self.x) + ', '+ str(self.y) + ', '+ str(self.z))
  
return s

def get_xyz(self):
return x,y,z

def set_xyz(self,a,b,c):
self.x = float(a)
self.y = float(b)
self.z = float(c)

def __add__(self, other)

hacer = Vector(0,0,0)
print(hacer)

hacer.set_xyz(3.2,4.4,8.5)

print(hacer)

r = hacer.magnitude()
print(r)

Test 3 add A vec3d: 1.50, 2.00, 3.00 B vec3d: 5.30, 8.00, 11.00 C vec3d: 6.80, 10.00, 14.00 actual C vec3d: 6.80, 10.00, 14.00 expect

Explanation / Answer

I have modified the add method as asked.

Here is the code

---------------------------------------------------------------------------------------------------

from math import *

class Vector:
    x = 0
    y = 0
    z = 0

    def __init__(self,x,y,z):
        self.x = float(x)
        self.y = float(y)
        self.z = float(z)

    def __str__(self):
        s = str('vec3d: ' + str(self.x) + ', '+ str(self.y) + ', '+ str(self.z))
      
        return s

    def get_xyz(self):
        return self.x,self.y,self.z

    def set_xyz(self,a,b,c):
        self.x = float(a)
        self.y = float(b)
        self.z = float(c)

    def __add__(self, other):
        x1,y1,z1 = other.get_xyz()
        x2 = self.x + x1
        y2 = self.y + y1
        z2 = self.z + z1
        return x2,y2,z2

hacer1 = Vector(3.2,4.4,8.5)
print hacer1
hacer2 = Vector(2.3,3.4,7.8)
print hacer2
r1,r2,r3 = hacer1.__add__(hacer2)
result = Vector( r1,r2,r3 )
print result
