SyntaxError: Missing parentheses in call to 'print' when running on Python3

[marcomc]

The requirements say Python 3.6.0 is required but in reality, it looks like the code has been written with Python2 standards in fact if I run the application with Python 3.x it fails as follow:

python /usr/local/bin/macprefs restore
  File "/usr/local/bin/macprefs", line 23
    print 'Backup Complete.'
                           ^
SyntaxError: Missing parentheses in call to 'print'

if I run it in Python 2 it works fine

are you planning to adapt the code?

The README does claim python 3.6 is required, is that not accurate? Having this issue as well.

@clintmod any guidance here? I'm having the same issue

$ python --version
Python 3.9.7
$ macprefs backup
  File "/usr/local/bin/macprefs", line 23
    print 'Backup Complete.'
          ^
SyntaxError: Missing parentheses in call to 'print'. Did you mean print('Backup Complete.')?

But when I uninstall python3, I get this

$ python --version
Python 2.7.16
$ macprefs backup

Ya sorry it's python 2.

[Bobronium]

I was able to get it working with python 3 by converting it with 2to3 tool and changing one line:

entrypoint=$(readlink -f $(which macprefs)) \
    && sudo 2to3 -W -n $entrypoint $(dirname $entrypoint) \
    && before=$(cat $entrypoint) \
    && sed 's/== "None"/is None/' $entrypoint | sudo tee $entrypoint | diff <(echo $before) -

Works:

macprefs
macprefs --help
macprefs --version
macprefs backup

Doesn't work:

macprefs --verbose backup  # UnicodeDecodeError: 'utf-8' codec can't decode byte 0xe2 in position 382: invalid continuation byte

Haven't tried:

macprefs restore
macprefs --verbose restore

I got the same error, How do i resolve this. Please help
