#### Python packaging on Nix
On Nix all packages are built by functions. The main function in Nix for building Python packages is [`buildPythonPackage`](https://github.com/NixOS/nixpkgs/blob/master/pkgs/development/python-modules/generic/default.nix).

Let's see how we would build the `toolz` package. According to [`python-packages.nix`](https://raw.githubusercontent.com/NixOS/nixpkgs/master/pkgs/top-level/python-packages.nix) `toolz` is build using

instead of installing the package this command creates a special link to the project code.
That way, you can run updated code without having to reinstall after each and every change you make.
Development mode is also available on Nix as [explained](http://nixos.org/nixpkgs/manual/#ssec-python-development) in the Nixpkgs manual.
Let's see how you can use it.

In the previous Nix expression the source was fetched from an url. We can also refer to a local source instead using
