This is more about platform support than about implementation support. An implementation using a C "float" or "double" (or whatever the equivalent in another implementation language) will de facto support IEEE 754 on platforms that support it. Sure, a Python implementation may also choose to rewrite its own floating-point type from scratch, but that sounds unlikely.
