The Python package HomotoPy for manipulating the aromatic forms and the aromatic bicomplex.
HomotoPy represents aromatic forests as dictionaries. It contains the functions from the paper (Euler operators, horizontal, vertical, variational derivatives, homotopy operators,...), as well as understandable examples to manipulate the bicomplex.
