This module contains a set of functions for vectorized string
operations and methods.

.. note::
   The `chararray` class exists for backwards compatibility with
   Numarray, it is not recommended for new development. Starting from numpy
   1.4, if one needs arrays of strings, it is recommended to use arrays of
   `dtype` `object_`, `string_` or `unicode_`, 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`.

    For an operation on two ndarrays, if at least one is unicode, the
    result should be unicode.

    Helper function for delegating arguments to Python string
    functions.

    Many of the Python string operations that have optional arguments
    do not use 'None' to indicate a default value.  In these cases,
    we need to remove all `None` arguments, and those following them.

    chararray(shape, itemsize=1, unicode=False, buffer=None, offset=0,
              strides=None, order=None)

    Provides a convenient view on arrays of string and unicode values.

    .. note::
       The `chararray` class exists for backwards compatibility with
       Numarray, it is not recommended for new development. Starting from numpy
       1.4, if one needs arrays of strings, it is recommended to use arrays of
       `dtype` `object_`, `string_` or `unicode_`, and use the free functions
       in the `numpy.char` module for fast vectorized string operations.

    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. `.endswith`) and infix operators (e.g. ``"+", "*", "%"``)

    chararrays should be created using `numpy.char.array` or
    `numpy.char.asarray`, rather than this constructor directly.

    This constructor creates the array, using `buffer` (with `offset`
    and `strides`) if it is not ``None``. If `buffer` is ``None``, then
    constructs a new array with `strides` in "C order", unless both
    ``len(shape) >= 2`` and ``order='Fortran'``, in which case `strides`
    is in "Fortran order".

    Parameters
    ----------
    shape : tuple
        Shape of the array.
    itemsize : int, optional
        Length of each array element, in number of characters. Default is 1.
    unicode : bool, optional
        Are the array elements of type unicode (True) or string (False).
        Default is False.
    buffer : int, optional
        Memory address of the start of the array data.  Default is None,
        in which case a new array is created.
    offset : int, optional
        Fixed stride displacement from the beginning of an axis?
        Default is 0. Needs to be >=0.
    strides : array_like of ints, optional
        Strides for the array (see `ndarray.strides` for full description).
        Default is None.
    order : {'C', 'F'}, optional
        The order in which the array data is stored in memory: 'C' ->
        "row major" order (the default), 'F' -> "column major"
        (Fortran) order.

    Examples
    --------
    >>> charar = np.chararray((3, 3))
    >>> charar[:] = 'a'
    >>> charar
    chararray([['a', 'a', 'a'],
           ['a', 'a', 'a'],
           ['a', 'a', 'a']],

    >>> charar = np.chararray(charar.shape, itemsize=5)
    >>> charar[:] = 'abc'
    >>> charar

           ['abc', 'abc', 'abc'],
           ['abc', 'abc', 'abc']],

jt�S(s�	
    Create a `chararray`.

    .. note::
       This class is provided for numarray backward-compatibility.
       New code (not concerned with numarray compatibility) should use
       arrays of type `string_` or `unicode_` and use the free functions
       in :mod:`numpy.char <numpy.core.defchararray>` 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).

      1) values automatically have whitespace removed from the end

    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

        is of type str or unicode, then the `obj` string will be
        chunked into `itemsize` pieces.

    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'}, 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).
