Not in Python source code.  I don't see why you'd want that.

Of course, C code has this and has always had this, e.g. the "i"
format code in PyArg_ParseTuple().

A wise man once said: worrying is interest paid on problems not yet
due.

I think NumPy has a way to create arrays whose elements are
variously-sized machine ints and floats.  I don't know that it has
corresponding scalar types -- I thing these all get mapped to the
standard Python types.
