so you have a problem with python, not the database!
if you're not "loop-proficient", massage it first to a dictionary, then
loop over it
from collections import defaultdict
resultset = defaultdict(list)
for row in parents_and_childs:
resultset[row.parent_record.id].append(row)
then you can
for k,v in resultset.iteritems():
print v[0].parent_record.name
for child in v:
print child.child_record.name
etc etc etc
