Go和Cython之间的差异

Question

Today a great friend of mine asked me what are the main differences between the newest Go language and Cython, which is a set of C-extensions for Python. I don't have much knowledge on Python, can anyone tell me why Go is better/worse than Cython?

Answer 1

Cython isn't really a language in the conventional sense. It is a preprocessor for building Python extensions that takes Python-like syntax (actually they strive for full Python compatibility) and produces C code (using the Python C API). Doing this they are able to include some special case optimisations, but the real benefits come when you add Cython specific static type information which is incorporated into the C code, bypassing the Python runtime for those operations and resulting in a high speed up.

Go is a compiled programming language. The first thing that can be done in Go is producing an executable that doesn't include the Python runtime/start a Python interpreter - this is impossible in Cython. (May not be technically impossible - but there is really no point to use Cython if you are not working with Python). Since Cython just produces C most of your questions in the comment don't really apply - you can use any C debugger (although the fact that's a Python extension makes things a bit more complicated).
