Ask HN: Real world examples of interaction between Python and Go?

6 points by wareotie 8 years ago | 4 comments

My manager allows me to use some of my time on personal projects so I started a library for an internal tool. More as a learning project that anything else, but now, it seems is useful for other people.

The thing is, the library is completely written in Go and I would like to use it as a Python library.

I found a few blog posts but I cannot find real world examples of libraries written in Go but been use from Python and I feel a little lost.

Anyone knows public repos like this?

Sadly the experiment I did isn't public. My memory is I compiled the Go thing to a shared library, and exposed a C API, and then used cffi to talk to the C API (based on https://blog.filippo.io/building-python-modules-with-go-1-5/, except cffi instead of Python C API).

Go objects needed to be managed C style: internally Go thing had a map between integer identifier and object, and Python just got the integer identifier and had to manually tell Go code to deallocate.

I was recently trying to do something similar and looked/tried go as a solution but I ran into some initial issues around my own confidence that the shared lib would work and that I wouldn't eventually really mess up the deallocation step.

I'm not sure I'd recommend it, yeah...
