replace unicode by six.text_type
replace urlparse by six.moves.urllib.parse
remove the ignore for F821 from the flake8 config
PS: as there is a bug of pylint 1.9, six.moves.urllib.parse
should be import as follows:
e.g.
from doc of module six:
from six.moves.urllib.parse import urlparse
urlparse(endpoint).path
here:
from six.moves import urllib
urllib.parse.urlparse(endpoint).path
