    Python is just a pile of dicts/hashtables under the hood. Even the basic int type is actually a dict of method names:

    x = 1
print(dir(x))
['__abs__', '__add__', '__and__', '__bool__', '__ceil__', '__class__', '__delattr__', '__dir__', ... ]

    PS: I will never get away from the fact that user-space memory addresses are also basically keys into the page table, so it is hashtables all the way down - you cannot escape them.

      js is similar, though it does not include python’s precalculated numbers
      calculates integers from -5 to 256, see:

      > a = 100
> b = 100
> c = 1000
> d = 1000
> a is b
True
> c is d
False
