Could you please expand your acronyms? I interpret NSA as National Security Agency and NASA as the National Aeronautics and Space Administration (two agencies within the US Government). However, considering these are two entire agencies, it does not make sense to say that either is 'written in python'. They may use Python, but I know that they also rely heavily on other languages including C, C++, Java, C#, OCaml, and assembly among others.
