Python packages

[Moritz Tacke]

Hi,

I am trying to use guix to install packages that debian does not
offer. However, in most cases (python modules) the package can't be
installed directly using guix as the package file is missing. What is the
correct way to proceed for e.g. a pypi module? I am currently creating a
package file myself, but is this the way it's meant to be? Is there a
standard place to store such custom scm files?
Greetings!
