Fails on Python 3

[mauritsvanrees]

I tried running this with Python 3.8 but it failed:

$ bin/zopeedit --help
Traceback (most recent call last):
  File "bin/zopeedit", line 14, in <module>
    import collective.zopeedit.zopeedit
  File "/Users/maurits/tmp/external/src/collective.zopeedit/collective/zopeedit/zopeedit.py", line 346
    os.chmod(self.input_file, 0777)
                                 ^
SyntaxError: leading zeros in decimal integer literals are not permitted; use an 0o prefix for octal integers

Fixing this just leads to the next error:

$ bin/zopeedit --help
Traceback (most recent call last):
  File "bin/zopeedit", line 14, in <module>
    import collective.zopeedit.zopeedit
  File "/Users/maurits/tmp/external/src/collective.zopeedit/collective/zopeedit/zopeedit.py", line 375
    raise exc, exc_data
             ^
SyntaxError: invalid syntax

I don't use zopeedit, I just wanted to try it out for plone/Products.CMFPlone#3190.
So I am not going to work on this. This is just a marker so people can see it does not yet work on Python 3.

Are there plans for Python 3?
