Python3: AttributeError: 'str' object has no attribute 'decode'

Anonymous created an issue

Hi,

I am trying out savReaderWriter on python3.3.0 and I've installed the py3k package that was in issue #8 (https://bitbucket.org/fomcl/savreaderwriter/get/py3k.zip) and I get this error while trying to write spss-file: AttributeError: 'str' object has no attribute 'decode' at savWriter.py, line 239 in writerow self._pyWriterow(record) and in line 261 in _pyWriteRow value = template % value.decode(encoding), when for example trying to run wiki's typical use example (at the end of Write Spss system files section).

    Hi,

    Yes, the Py3k version is not quite ready yet. That applies in particular to SavWriter, where I stopped coding while messing with the writerow method. I think it is fairly easy to make a working version and I will see if I can (finally!) make some time for this week. String (Python 2) substitution (%s) is not possible with Python 3 bytes objects and I was struggling to find a nice and efficient way to deal with this. Efficiency is especially important for the writerow method, which may be called millions of times. Perhaps I should make two implementations, one for Python 2 and one for Python 3. I hate using "if sys.version_info[0] > 2" in the code too much though!

    Regards, Albert-Jan
