This code was written for Python 2, that’s why you get a conflict in Python 3, i cannot see another way than below to set the new method on the QuerySet object :

from django.db import connections
from django.db.models.query import QuerySet

def explain(self):
    cursor = connections[self.db].cursor()
    query, params = self.query.sql_with_params()
    cursor.execute('explain %s' % query, params)
    return '\n'.join(r[0] for r in cursor.fetchall())

type.__setattr__(QuerySet, 'explain', explain)

I hope this can help you.
