There are several reasons why Go is gaining popularity. Single-file executables is definitely a reason; it makes deployment very easy, even if it increases the maintenance burden (e.g. without shared libraries, you have multiple copies of things so when a security fix is required for one of those things you have to recompile the world). Start up times and memory footprint are also factors. Probably not much to be done about the latter, but perhaps PEP 432 can lead to improvements in the former. (Hey Nick, I'm guessing you'll want to bump that one back to 3.6.) Certainly better support for multi-cores comes up a lot. It should be a SMoE to just get rid of the GIL once and for all <wink>. One thing I've seen more than once is that new development happens in Python until the problem is understood, then the code is ported to Go. Python's short path from idea to working code, along with its ability to quickly morph as requirements and understanding changes, its batteries included philosophy, and its "fits-your-brain" consistency are its biggest strengths!

E.g. you really should be using the pkg_resources APIs for loading resources from your packages, otherwise you're gonna have problems with zip executables. We've talked before about adopting some of these APIs into Python's stdlib. pkgutil is a start, and the higher level APIs from pkg_resources should probably go there. Donald Stuff proposed importlib.resources a little while back to handle the storage-agnostic api dor reading data and I have been thinking about it for years. I plan to make it happen in Python 3.6. -brett Cheers, -Barry _______________________________________________ Python-Dev mailing list Python-Dev@python.org https://mail.python.org/mailman/listinfo/python-dev Unsubscribe: https://mail.python.org/mailman/options/python-dev/brett%40python.org
