To get a ``dict`` containing an encoding and its confidence, you can simply run: .. code:: u = UniversalDetector() u.feed(some_bytes) u.close() detected = u.result g�������?s [�-�]s (|~{)s [�-�]z Windows-1252z Windows-1250z Windows-1251z Windows-1256z Windows-1253z Windows-1255z Windows-1254z Windows-1257)z iso-8859-1z iso-8859-2z iso-8859-5z iso-8859-6z iso-8859-7z iso-8859-8z iso-8859-9z iso-8859-13c C sN d | _ g | _d | _d | _d | _d | _d | _|| _t� t �| _ d | _ | � � d S )N)�_esc_charset_prober�_charset_probers�result�done� _got_data� _input_state� _last_char� lang_filter�logging� getLogger�__name__�logger�_has_win_bytes�reset)�selfr � r ��/builddir/build/BUILDROOT/alt-python39-pip-21.3.1-2.el8.x86_64/opt/alt/python39/lib/python3.9/site-packages/pip/_vendor/chardet/universaldetector.py�__init__Q s zUniversalDetector.__init__c C sV dddd�| _ d| _d| _d| _tj| _d| _| jr>| j� � | j D ] }|� � qDdS )z� Reset the UniversalDetector and all of its probers back to their initial states.

After calling ``feed``, you can check the value of the ``done`` attribute to see if you need to continue feeding the ``UniversalDetector`` more data, or if it has made a prediction (in the ``result`` attribute). .. note:: You should always call ``close`` when you're done feeding in your document if ``done`` is not already ``True``.
