According to the [https://nixos.org/nixpkgs/manual/#contributing-guidelines official guidelines] for python new package expressions should be placed in <~~code~~>pkgs/development/python-modules/~~<~~name~~>~~/default.nix</~~code~~>. Those expressions are then referenced from <code>pkgs/top-level/python-packages.nix</code> like in this example:

According to the [https://nixos.org/nixpkgs/manual/#contributing-guidelines official guidelines] for python new package expressions should be placed in <syntaxhighlight lang="bash" inline>pkgs/development/python-modules/<name>/default.nix</syntaxhighlight>. Those expressions are then referenced from <code>pkgs/top-level/python-packages.nix</code> like in this example:

<~~pre class~~="nix">{

{

aenum = callPackage ../development/python-modules/aenum { };

}</~~pre~~>

}

</syntaxhighlight>

The reasoning behind this is the large size of <code>pkgs/top-level/python-packages.nix</code>. Unfortunately most libraries are still defined in-place in <code>pkgs/top-level/python-packages.nix</code>. If a change to library is necessary or an update is made, it is recommend to move the modified package out of <code>pkgs/top-level/python-packages.nix</code>.
