String operations
*****************

.. currentmodule:: numpy.char

.. module:: numpy.char

The `numpy.char` module provides a set of vectorized string
operations for arrays of type `numpy.string_` or `numpy.unicode_`.
All of them are based on the string methods in the Python standard library.

Comparison
----------

Unlike the standard numpy comparison operators, the ones in the `char`
module strip trailing whitespace characters before performing the
comparison.
