class Vector2D: def __init__(self, x, y): self.x = x self.y = y def __add__(self, other): return

please someone should help me correct the errors I made here and indicate what you have done to make it run successfully

So let's say that you have your (x,y) coordinates (5,4) and you want to add a number (3) to both of them (output (8,7)): class Vector2D: def __init__(self, x, y): self.x = x self.y = y # On return add other to both x and y def __add__(self, other): return self.x + other, self.y + other # Create an instance of the class with the initial values a = Vector2D(5,4) # add 3 to both x and y and print print(a+3)

class Vector2D: def __init__(self, x, y): self.x = x self.y = y def __add__(self, other): return Vector2D(self.x + other.x, self.y + other.y) first = Vector2D(5, 7) second = Vector2D(3, 9) result = first + second print(result.x) print(result.y) I also was didn't understand this code,but i referred some youtube videos and finally, i try to explain you at my best level. in the second function of above code def __add__(self,other): #the self and other are act as two variables,if you want you can the change the variable name. As example def __add__(K,D) For those who didnt get this line, self.x =5 ,self.y =7 and self.y =3,other.y =9 #in case you changed the name of variable then dont forget to update this line. We take our previous example :- return Vector2D(K.x + D.x, K.y + D.y) if i did any mistake while explaining this code,please correct me. i hope you got the idea about this code,Thank You.
