I have been looking at my plugins and my biggest question so far is how to handle urllib2 in a way that will work with both Python 2.7 and 3.7.7. Everything else just seems to be adding parentheses to print functions.
I found this Cheat Sheet: Writing Python 2-3 compatible code that suggests:
# Python 2 and 3: easiest option
from future.standard_library import install_aliases
install_aliases()
from urllib.parse import urlparse, urlencode
from urllib.request import urlopen, Request
from urllib.error import HTTPError
However, trying that in Cinema 4D threw this error:
ImportError: No module named future.standard_library
Fortunately, there are some alternatives to try, like
# Python 2 and 3: alternative 4
try:
from urllib.parse import urlparse, urlencode
from urllib.request import urlopen, Request
from urllib.error import HTTPError
except ImportError:
from urlparse import urlparse
from urllib import urlencode
from urllib2 import urlopen, Request, HTTPError
From that article: "urllib is the hardest module to use from Python 2/3 compatible code."
