A lot of things here are not so easy. I have recently decided to try Golang in my new project, personal finance tracker website. So far, two weeks passed,it is awful, rewritten the code several times. In Python you can drop third-party modules in and you;’re done. With Golang — not so, there are no ORMs, no normal social login, like python-social-auth, everything needs too be hacked. If you decide to use some plugin, then other plugin’s don’t fit, etc. Definitely not for complex projects.
And when you put it all together, benchmarks are not so different from Django. I’m yet to find benefits of using Go, maybe just for micro-services or APIs, then yes.
