解决办法：
在import os之后添加
os.environ['DJANGO_SETTINGS_MODULE'] = 'myTest.settings'    # myTest是项目名称


node2:/zjzc/mysite#cat a1.py 
import os
os.environ['DJANGO_SETTINGS_MODULE'] = 'mysite.settings'
from polls.models import Question
for e in Question.objects.all():
  print e
node2:/zjzc/mysite#python a1.py
