Python is my go-to language and I write big batch jobs in it and profile them and use PyPy. I do it because it's so clean and concise.

Recent C++ with lambda and auto is much improved but still not nearly as productive as Python.

Likewise lambda has really made Java better, but lack of type inference really makes it clunky to write.

I really want a statically typed Python. But because I don't have it, I choose Python for the syntax over c++/Java even for performance critical code.
