Which line of code is printing [4] and [4, 5, 6, 7] in the output?

from tracer import Tracer
@Tracer
class MyList(list):
    def __init__(self, *args):
        print("INSIDE MyList")
        print(*args)
        x = MyList([1, 2, 3])
x.append(4)
print(x.wrapped)
WrapList = Tracer(list)
x = WrapList([4, 5, 6])
x.append(7)
print(x.wrapped)

OUTPUT:
