Explain please. What does other.x means

Question

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)

output
>>> 8
>>> 16

Answer 1

# If you understand that 'other'
# represents an instance then,
# To address your question directly other.x
# means get the value x of the instance I am passing in
# as one of the arguments on the call to __add__

# It might help to look at it this way.
#'other' is just a parameter to represent a class instance.
#just as 'self' is representative of a class instance .
#If you want to think about what is really going on here
#in this specific example you can imagine it like this by changing the code
#to mimic the instance names.

class Vector2D:
def __init__(first, x, y):
first.x = x
first.y = y
def __add__(first, second):
return Vector2D(first.x + second.x, first.y + second.y)

# instance of a Vector2D class object
first = Vector2D(5, 7)
# another of a Vector2D class object
second = Vector2D(3, 9)

result = first + second

# results of addition using the class method
print(result.x)
print(result.y)

# the code gives the same result as the original showing that
# the parameter names can be anything.
# They are just representing the two class instances.
#However! other than when you are trying
# to figure out ,while learning ,how class methods work and
# what 'self' or 'other.x' might mean stick to using
# self and meaningful names in class methods you construct because it is
# convention to do and once you understand
# the process it makes a lot more sense to do so.

Answer 2

Other Vector2D object

Answer 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.
