The hec-python-library equivalent of Jython method **periodConstants()**:

.. include:: _in_place.rst

**Example:**

.. code-block:: python

    ts3 = ts1.resample("prev", ts2, before="missing")

Convenience method for calling ``periodConstants(...)`` with ``in_place=True``.

**Example:**

.. code-block:: python

    ts1.iresample("prev", ts2, before="missing")
