└── $HOME
    └── go
        ├── bin

go run 01_hello.go

Built-in linter:

gofmt -w 01_hello.go

go build -buildmode=c-shared -o 01_hello.so 01_hello.go

This creates 2 files, 01_hello.h and 01_hello.so. The 01_hello.so file is the compiled binary and 01_hello.h is the header to describe what methods and types are defined within the binary. Then the shared library can be imported in C or Python...
