you write: "requirements.txt doesn't tell me which version of Python the code was developed with". Do you expect to have less pain with any othe rlanguage with this situation?

I'm not saying other languages don't have the same problems, but this just hasn't been as much of an issue in my experience when working with other languages.

C# for example - I had some compatibility issues between versions 2 and 3.1 of .NET Core, but at least the .csproj tells me what version it's supposed to be built with, and the LangVersion property indicates the version of C#.

Rust has a way to specify the minimum rustc version.

Rust is so cool. In python's requirements.txt you can put something like:

tensorflow >=1.12,!=2.1.*

“Here is a binary” sounds a lot less painful.
