It's been some time since I programmed in Python and it left a good impression with some caveats. I remember being bothered by the lack of a strong type checker. I see that now there is MyPy. Good to know. The other problem is the lack of a super fast runtime. A Python to C compiler would be great. I remember using Cython but didn't like it that much, even though it was much faster then normal Python;
