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. WimPyDD can be downloaded and
