Starting from numpy 1.4, if one needs arrays of strings, it is recommended to use arrays of `dtype` `object_`, `bytes_` or `str_`, and use the free functions in the `numpy.char` module for fast vectorized string operations. Some methods will only be available if the corresponding string method is available in your version of Python. The preferred alias for `defchararray` is `numpy.char`.

New code (not concerned with numarray compatibility) should use arrays of type `bytes_` or `str_` and use the free functions in :mod:`numpy.char ` for fast vectorized string operations instead. Versus a regular NumPy array of type `str` or `unicode`, this class adds the following functionality: 1) values automatically have whitespace removed from the end when indexed 2) comparison operators automatically remove whitespace from the end when comparing values 3) vectorized string operations are provided as methods (e.g. `str.endswith`) and infix operators (e.g. ``+, *, %``) Parameters ---------- obj : array of str or unicode-like itemsize : int, optional `itemsize` is the number of characters per scalar in the resulting array. If `itemsize` is None, and `obj` is an object array or a Python list, the `itemsize` will be automatically determined. If `itemsize` is provided and `obj` is of type str or unicode, then the `obj` string will be chunked into `itemsize` pieces. copy : bool, optional If true (default), then the object is copied. Otherwise, a copy will only be made if __array__ returns a copy, if obj is a nested sequence, or if a copy is needed to satisfy any of the other requirements (`itemsize`, unicode, `order`, etc.). unicode : bool, optional When true, the resulting `chararray` can contain Unicode characters, when false only 8-bit characters. If unicode is None and `obj` is one of the following: - a `chararray`, - an ndarray of type `str` or `unicode` - a Python str or unicode object, then the unicode setting of the output array will be automatically determined. order : {'C', 'F', 'A'}, optional Specify the order of the array. If order is 'C' (default), then the array will be in C-contiguous order (last-index varies the fastest). If order is 'F', then the returned array will be in Fortran-contiguous order (first-index varies the fastest). If order is 'A', then the returned array may be in any order (either C-, Fortran-contiguous, or even discontiguous).
