WimPyDD is a modular, object–oriented and customizable Python code that calculates accurate predictions of nuclear scattering expected rates for Weakly Interacting Massive Particle (WIMP) direct–detection experiments and capture in celestial bodies within the framework of Galilean–invariant non–relativistic effective theory (NREF) in virtually any scenario, including inelastic scattering, an arbitrary WIMP spin and a generic WIMP velocity distribution in the Galactic halo. I will show the capabilities of WimPyDD in several practical examples: 1) the study of the phenomenology of the NREFT for a WIMP of spin up to J=2; 2) the maximal variation of the exclusion plot for each of the Wilson coefficients of the NREFT due to the interference among different operators; 3) the calculation of improved constraints on inelastic dark matter from their capture and annihilation in white dwarves; 4) the extension to low WIMP masses of the direct detection bounds to operators up to dimension 7 of the relativistic effective field theory describing WIMP interactions with quarks and gluons using the Migdal effect; 5) the determination of the halo-independent bounds on each of the couplings of the NREFT for a WIMP of spin 1/2. WimPyDD allows to explore in a fast and efficient way theoretical scenarios with a large parameter space by encoding the properties of the target in tabulated response functions that are interpolated at run time and do not depend on the WIMP mass, on the halo function or on the parameters of the effective Hamiltonian.
