  In this work, we present a software package in Python for high-throughput
first-principles calculations of thermodynamic properties at finite
temperatures, which we refer to as DFTTK (Density Functional Theory Tool Kit).
DFTTK is based on the atomate package and integrates our experiences in the
last decades on the development of theoretical methods and computational
software. It includes task submissions on all major operating systems and task
execution on high-performance computing environments. The distribution of the
DFTTK package comes with examples of calculations of phonon density of states,
heat capacity, entropy, enthalpy, and free energy under the quasi-harmonic
phonon scheme for the stoichiometric phases of Al, Ni, Al3Ni, AlNi, AlNi3,
Al3Ni4, and Al3Ni5, and the fcc solution phases treated using the special
quasirandom structures at the compositions of Al3Ni, AlNi, and AlNi3.
