a small doubt in MAgical Methods

Question

return self.cont[index + random.randint(-1, 1)] why don't we use VagueList instead of self.cont ,,. i mean return VagueList[index + random.randint(-1, 1)] ,,,. As we used previously in Vector2D Example

---> Please look down at two examples @Return Values

Example1:import random

class VagueList:
def __init__(self, cont):
self.cont = cont

def __getitem__(self, index):
return self.cont[index + random.randint(-1, 1)]

def __len__(self):
return random.randint(0, len(self.cont)*2)

vague_list = VagueList(["A", "B", "C", "D", "E"])
print(len(vague_list))
print(len(vague_list))
print(vague_list[2])
print(vague_list[2])

Example2:
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)

Answer 1

Nice work.
