This is due, for the most part, to the difference between str in Python 2 and Python 3. The semantics of Python 3's version are more useful because they support unicode natively, while Python 2's csv does not. Installation ============ .. code-block:: sh pip install backports.csv Usage ===== First make sure you're starting your file off right: .. code-block:: python from backports import csv Then be careful with your files to handle the encoding. If you're working with a binary file-like object, ``io.TextIOWrapper`` can be very helpful. If you're dealing with a file, you can just use ``io.open`` instead of Python 2's ``open`` builtin, and it works just like Python 3's builtin ``open``. .. code-block:: python from backports import csv import io def read_csv(filename): with io.open(filename, newline='', encoding='utf-8') as f: for row in csv.reader(f): yield row def write_csv(filename, rows): with io.open(filename, 'w', newline='', encoding='utf-8') as f: writer = csv.writer(f) for row in rows: writer.writerow(row) Note: It should always be safe to specify ``newline=''``, since the csv module does its own (universal) newline handling.
