登录模拟账户后，打印账户，Position持仓对象遇到问题！

Position 是持仓对象，print(position),可以打印出一个字典，但是只打印其中的一个，或几个参数，比如：print(position.pos_long_his)就报错。请教一下大家这是为什么呀？

from tqsdk import TqApi, TqAccount

api = TqApi(TqAccount(“快期模拟”, “XXXXX”, “XXXXX”))
position = api.get_position(“SHFE.hc2010”)
print(position)
api.close()
终端显示结果：
