<p>To allow arbitrarily complex computations to be performed, <span class="sc">Psi4</span> is built
upon the Python interpreter, with modifications termed Psithon. Sec.
<a class="reference internal" href="psithoninput.html#sec-psithoninput"><span>Psithon: Structuring an Input File</span></a> describes the non-standard Python associated with
clean molecule, basis, and option specification in the <span class="sc">Psi4</span> input file.
This documentation addresses the pure Python side- what functions allow
the efficient compiled code to be run, what functions post-process and
interact with that output, and how the ordinary (or ambitious) user can
extent <span class="sc">Psi4</span>&#8216;s functionality.</p>
