Emacs plugin which uses importchecker to find out the unused import in the Python source code. It hits out the output in the grep buffer.
I have distributed it through [Melpa] (https://melpa.org/#/py-import-check) and [Marmalade] (http://marmalade-repo.org/packages/py-import-check) but incase you want to install it manually, just use the py-import-check.el file.
You need to install importchecker program for using the plugin. On a *nix based system, this can be achieved by this command:
sudo pip install importchecker
You can invoke it through py-import-check function or alternatively bind it to any key bindings.
