Nature of problem:
Setting up state-of-the-art methods for an ab initio description of correlated systems from scratch requires a lot of code development. In order to make these calculations possible for a larger community there is need for high-level methods that allow the construction of DFT+DMFT calculations in a modular and efficient way.

Solution method:
We present a Fortran/Python open-source computational library that provides high-level abstractions and modules for the combination of DFT with many-body methods, in particular the dynamical mean-field theory. It allows the user to perform fully-fledged DFT+DMFT calculations using simple and short Python scripts.

Running time:
Tests take less than a minute; otherwise highly problem dependent.
