How Can I Use Goroutines in a Python Extension Written in Go?

Writing a Python Extension in Go (Golang): From Cython to Goroutines

For those using Cython to seamlessly integrate C and Python, harnessing the concurrency prowess of goroutines via a Python extension might seem like an attractive upgrade. However, connecting goroutines with Python can pose a challenge.

Initial Considerations

Simplexity is key, so exploring options that reduce the need for additional layers, such as C or Cython, is preferred. One might assume that Python's limitations preclude such a direct approach, but advancements in Go make it possible.

Advancements in Go

As of Go 1.5, developers can construct .so objects and import them as Python modules, executing Go code directly within Python. This breakthrough opens up the possibility of incorporating highly parallelizable goroutines into Python code.

Leveraging GoPy

For further convenience, consider leveraging GoPy, a robust tool that generates CPython extension modules from Go packages. By leveraging GoPy, developers can seamlessly connect Go code with Python, creating a streamlined workflow and eliminating the need for intermediate layers.
