The main differences between ``newstr`` and Python 2.x's ``unicode`` type are the stricter type-checking and absence of a `u''` prefix in the representation. It is designed to be used together with the ``unicode_literals`` import as follows: >>> from __future__ import unicode_literals >>> from builtins import str, isinstance On Python 3.x and normally on Python 2.x, these expressions hold >>> str('blah') is 'blah' True >>> isinstance('blah', str) True However, on Python 2.x, with this import: >>> from __future__ import unicode_literals the same expressions are False: >>> str('blah') is 'blah' False >>> isinstance('blah', str) False This module is designed to be imported together with ``unicode_literals`` on Python 2 to bring the meaning of ``str`` back into alignment with unprefixed string literals (i.e. ``unicode`` subclasses). Note that ``str()`` (and ``print()``) would then normally call the ``__unicode__`` method on objects in Python 2. To define string representations of your objects portably across Py3 and Py2, use the :func:`python_2_unicode_compatible` decorator in :mod:`future.utils`. � )�Number)�PY3�istext�with_metaclass� isnewbytes)�no�issubset)� newobject)�Iterablec @ s e Zd Zdd� ZdS )� BaseNewStrc C s" | t krt|t�S t|j| �S d S �N)�newstr� isinstance�unicode� issubclass� __class__)�cls�instance� r �5/usr/lib/python3/dist-packages/future/types/newstr.py�__instancecheck__; s z BaseNewStr.__instancecheck__N)�__name__� __module__� __qualname__r r r r r r : s r c s" e Zd ZdZdZ� fdd�Z� fdd�Z� fdd�Zd d � Ze d �� fd d ��Z e d �dd� �Z � fdd�Z � fdd�Z � fdd�Ze d �� fdd��Ze d �� fdd��Ze d d�� fdd ��Zd d � ZdT� fd!d"� Ze d d#�� fd$d%��Ze d d#�� fd&d'��Ze d d#�dU� fd*d+� �Ze d d#�dV� fd,d-� �Ze d d#�� fd.d/��Ze d d#�� fd0d1��Ze d d#�d2d3� �ZdW� fd5d6� Z� fd7d8�Z � fd9d:�Z � fd;d<�Z d=Z � fd>d?�Z � fd@dA�Z!� fdBdC�Z"� fdDdE�Z#� fdFdG�Z$dHdI� Z%e&dXdJdK��Z'dLdM� Z(dNdO� Z)dPdQ� Z*dRdS� Z+� Z,S )Yr z6 A backport of the Python 3 str object to Py2 z,Can't convert '{0}' object to str implicitlyc s� t |�dkr tt| ��| �S t|d �tkr<| tkr<|d S t|d t�rT|d }nRt|d t�r�d|ksvt |�dkr�|d j|dd� |�}q�|d � � }n|d }tt| ��| |�S )a/ From the Py3 str docstring: str(object='') -> str str(bytes_or_buffer[, encoding[, errors]]) -> str Create a new string object from the given object.
