      Call Stack Frame (Names / Pointers)
      Variable a→ Pointer: 0x7f1a000
      Variable b→ Pointer: 0x7f1a000
      CPython Heap (PyObject Headers)
      Address: 0x7f1a000refcnt: 2
      PyLongObject: 100
      Equality (`a == b`)
      True
      Compares values
      Identity (`a is b`)
      True
      Compares memory addresses `id(a) == id(b)`
      Python CPython Architecture Insight:

      Python pre-allocates an internal array of integer objects for values between -5 and 256 at interpreter startup. When you assign any integer in this range, Python points to the cached singleton PyObject rather than allocating a new object on heap!
