I think you typed "python" wrong :) Duck typing is a python thing. And the dependency management is a nightmare, constantly breaking. To the article's point - you _must_ run it in a container and defer to the OS to have anything resembling a sane development story.

Ok that's totally fair. What's the Go name for it? In my mind Go interfaces are duck typed.

  mostly joking - your complaints are big problems in python. Dependency management in Go has been contentious (historically) with "to vendor or not to vendor", glide and dep, GOPATH, etc. But that is all solved. Go mod for the win. As far as "the nightmare of {using interfaces}" -- I have no clue to any controversy there. It is one of the most celebrated features of Go. Not sure where you were going with that. In Python, I do find duck typing to be a nightmare because you don't actually _know_ what you have. Can you change it? Try it and if it breaks you will know. Or you use it like a list but it is a string and that gives strange, unexpected behavior, so you end up doing things like `param=force_list(maybe_string_or_list)`.

    The Python typing nightmares you refer to go away on large projects as soon as you start using mypy, which I tend to find most large projects do these days. So yes, you can change that string and you do know. It's still better that it's optional and gradual - it's unnecessary overhead on smaller projects, spikes, notebooks, etc. which are what most big projects grow out of.

      Python typing nightmares definitely do not just go away with the use of mypy. There are so so many ways to break out of the guardrails it supplies that are not caught.

        I can write stringly typed code in haskell too if it comes to that.

      Don't you need stumps which are quite often not available?

  What were they actually doing? Passing interface{} all the time and casting it?
  - throwawa14223 3y ago
    Haha you're spot on. In the codebase I inherited that was everywhere.

      You can do crazy things in any language if you try hard enough.

        The trick to efficient Go is to not try hard, lol

  Python is duck typed as it support dynamic type, whereas Go doesn't. Yet you can do polymorphism in Go and aside that difference I think Go interface are duck typed.

  Probably structural typing?

I think you typed “JavaScript” wrong… ;)

OP meant structured typing, which is the strong type version of duck typing. As long as the type supports the same interface anything goes, even it actually supports another one, where the methods have the same name, with different semantics.
