pymarc generates AttributeError: 'str' object has no attribute 'decode'

[Lee LeBlanc]

Hi All, 

Trying to run this script markbart.py but I'm getting this error below. I think this is about pymarc perhaps holding things up. If my question sounds strange that's because my knowledge of python mostly comes from watching nature documentaries and living close to the Florida Everglades. 

  File "marckbart.py", line 27, in <module>

    for record in reader:

  File "C:\Program Files\Python36-32\lib\site-packages\pymarc\reader.py", line 97, in __next__

    utf8_handling=self.utf8_handling)

  File "C:\Program Files\Python36-32\lib\site-packages\pymarc\record.py", line 74, in __init__

    utf8_handling=utf8_handling)

  File "C:\Program Files\Python36-32\lib\site-packages\pymarc\record.py", line 231, in decode_marc

    self.leader = marc[0:LEADER_LEN].decode('ascii')

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

Tried changing the file encoding to UTF-8. And I first cleared this error about file -which is no longer supported -and should read open? I think I understand that this bit of code must read 

fd = open(SRC_DIR + '/' + item, 'r') instead of file.

Any help appreciated -thanks!

Hi Lee,

In Python 3, you need to open the file in 'rb' mode, since MARC is a binary format and the Python 3 open() with 'r' mode would do decoding to unicode (called "str" in py3) objects.

(In Python 2, 'r' mode only affected newline translation in Windows and did nothing at all on other platforms, so either mode would work the same.)
