How dose this code works?

Question

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])

Answer 1

Where do have doubt in code?
Do you have some idea any?

edit:

VagueList(["A", "B", " C", "D", "E"]) will automatically calls constructor method __init__() and assign self.cont to passed list.

len(vague_list) will automatically calls Overiden __len__() method . so return str at the index at (index+ random letter between (-1, 1 ).

valuge_list[2] calls Overiden length method and return random number between 0 to len(self.cont) *2
