Been writing Python code for about 10 years (C/Pascal/Assembly-style languages for 20 years prior to that) and was interested in Go for specific advantages: - coroutines - channels - simple one-file delivery - cross platform (I tend to develop on Mac and deploy on Linux or Windows) After writing Go for about a year now, I'm switching back to Python -- specifically Python 3.5. My (personal) issues with Go: - No basic support for NULLs in database responses (yes, there are third-party modules). - XML manipulation is a pain. - third-party module management problematic. - poor debugging environment. Switching back to Python and stepping up to Python 3.5 (and pyInstaller for single-file builds) addresses all the above pain points, plus introduces asyncio which is a seriously pleasant way to build asynchronous web/database applications. Rewrote a 1,000 line Go application in about 300 lines of Python using asyncio. In addition to the specifics, writing in Go simply was not enjoyable. A typical end of the day with Go felt like I'd (usually) gotten the tool to do what I needed. Contrast that to a typical end of the day with Python feeling like I'd been using a tool that always supported me. I'll continue to watch what Go is doing, but I'm back in Python (and playing with Elixir) for now.
