#89701 — Looks like Python 3 files do not confirm to Python 3

On my system in:
/usr/lib/python3.4/site-packages/ndg/httpsclient/ssl_peer_verification.py

it says:
    try:
        from ndg.httpsclient.subj_alt_name import SubjectAltName
        from pyasn1.codec.der import decoder as der_decoder
        SUBJ_ALT_NAME_SUPPORT = True
    except ImportError, e:
        SUBJ_ALT_NAME_SUPPORT = False
        SUBJ_ALT_NAME_SUPPORT_MSG = (
            'SubjectAltName support is disabled - check pyasn1 package '
            'installation to enable'
        )
        import warnings
        warnings.warn(SUBJ_ALT_NAME_SUPPORT_MSG)

which gives:
    File "/usr/lib/python3.4/site-packages/ndg/httpsclient/ssl_peer_verification.py", line 17
      except ImportError, e:

Does my system have outdated files, or are there still Python 3 files
that do not conform to Python 3?

The only real python program I use at the moment uses:
    import urllib3.contrib.pyopenssl

and then you get this error.


So another reason to stay with Python 2. (While still writing code
that works in Python3.)

ndg is a third-party package, not part of the Python 3 standard library.

I think you're missing the last line of the error. I'm guessing it was
probably NameError: name 'e' is not defined.

I would say, either you have accidentally installed a Python 2 file in your
Python 3 library, or it is simply a bug in ndg.

Oops, barking up to the wrong tree. Sorry.

Nope:
        except ImportError, e:
                          ^
    SyntaxError: invalid syntax

It is solved by:
    except (ImportError) as e:

But then:
        PARSER_RE_STR = '/(%s)=' % '|'.join(DN_LUT.keys() + DN_LUT.values())
    TypeError: unsupported operand type(s) for +: 'dict_keys' and 'dict_values'

I will contact the ndg people.

It is solved by making it:
    except (ImportError) as e:

The same for:
    /usr/lib/python3.4/site-packages/ndg/httpsclient/subj_alt_name.py

I would not mind to solve those and others if I could contribute them
to the Python community. What is the procedure for that?

You'll have to find out who supports ndg as it's not standard Python. 
The big clue is the site-packages folder name, that's used for third 
party packages.  From searching I think it's this 
https://github.com/cedadev/ndg_httpsclient/ but please don't quote me on 
that.

My fellow Pythonistas, ask not what our language can do for you, ask
what you can do for our language.

Yeah, I was barking up to the wrong tree.

I found an email address in the sources. The copyright is from 2012,
so hopefully it is still supported.
