gogopython

Python, but in Go.

CGO_ENABLED=0 go build

To run the test program, figure out your python home and paths:

python3 -c 'import sys; print(f"home={sys.prefix}\npaths={sys.path}")'

Run the test program:

go run cmd/main.go [your home] [each path entry]

note: home and path entries are optional, but if you're trying to use a virtualenv you'll need to set them
