Currently supports python-3.7 only.

Golang bindings for the C-API of CPython-3.

This package provides a

go

package named "python" under which most of the

PyXYZ

functions and macros of the public C-API of CPython have been exposed. Theoretically, you should be able use https://docs.python.org/3/c-api and know what to type in your

go

program.

This project was inspired by https://github.com/sbinet/go-python. Go and take a look if we need something for python-2.7!

Install

Deps

We will need

pkg-config

and a working

python3.7

environment to build these bindings. Make sure you have Python libraries and header files installed as well (

python3.7-dev

on Debian or

python3-devel

on Centos for example)..

By default

pkg-config

will look at the

python3

library so if you want to choose a specific version just symlink

python-X.Y.pc

python3.pc

or use the

PKG_CONFIG_PATH

environment variable.

Go get

Then simply

go get github.com/DataDog/go-python3

API

Some functions mix go code and call to Python function. Those functions will return and

int

and

error

type. The

int

represent the Python result code and the

error

represent any issue from the Go layer.

Example:

func PyRun_AnyFile(filename string)

open

filename

and then call CPython API function

int PyRun_AnyFile(FILE *fp, const char *filename)

Therefore its signature is

func PyRun_AnyFile(filename string) (int, error)

, the

int

represent the error code from the CPython

PyRun_AnyFile

function and error will be set if we failed to open

filename

If an error is raise before calling th CPython function

int

default to

-1

Take a look at some examples
