从this issue，将以下规则添加到您的query_1 = Example.query(ndb.AND(Example.field1='B' AND Example.field2='A'), projection=[Example.userid], distinct=True)) query_2 = Example.query(ndb.AND(Example.field1='D' AND Example.field2='C'), projection=[Example.userid], distinct=True)) users_1 = set([example.userid for example in query_1.fetch()]) users_2 = set([example.userid for example in query_2.fetch()]) users_list = list(users_1 & users_2) 文件中：

plt.show()
