What does this python code with 'metaclasses' output?

class Meta(type):
def __new__(cls, name, bases, dct):
x = super().__new__(cls, name, bases, dct)
x.attr = 100
return x

class MyClass(metaclass=Meta):
def __init__(self):
self.attr = 10

obj = MyClass()
print(obj.attr)

Guess the correct output:

import functools

def debug(func):
@functools.wraps(func)
def wrapper(*args, **kwargs):
args_repr = [repr(a) for a in args]
kwargs_repr = [f"{k}={v!r}" for k, v in kwargs.items()]
signature = ", ".join(args_repr + kwargs_repr)
print(f"Calling {func.__name__}({signature})")
result = func(*args, **kwargs)
print(f"{func.__name__} returned {result!r}")
return result
return wrapper

@debug
def add(x, y):
return x + y

print(add(3, y=4))

Choose the correct output (for the python code):

class Animal:
def speak(self):
return "I'm an animal"

class Dog(Animal):
def speak(self):
return super().speak() + " and a dog"

my_dog = Dog()
print(my_dog.speak())

The video for the "Not a Little Language" interpreter is in the works. It'll be an interpreter for a programming language with variables, types, if-elif-else, loops, etc. & some spicy exclusive features.

Would you be interested in seeing how to make a VSCode extension that does syntax highlighting for the language?
