"These are both errors in Python 3 since there's no such thing as 'unicode' or 'basestring'. But it's pretty simple to normalise the vocabulary between the two versions:

# 'unicode' is undefined, must be Python 3 str = str unicode = str bytes = bytes basestring = (str,bytes)
# 'unicode' exists, must be Python 2 str = str unicode = unicode bytes = str basestring = basestring "
