使用 pdblp 从bloomberg 为我的python 代码提取数据时出错

问题描述

我已经编写了代码来在我安装了bloomberg的桌面上尝试pdblp。我得到低于错误。有人能帮我解决这个问题吗

In [8]:import pdblp
con=pdblp.BCon(debug=True,port=8194,timeout=5000)
con.start

Out[8]:<bound method BCon.start of <pdblp.pdblp.BCon object at 0x00000178D754ECA0>>


In [9]:con.bdh('SPY US EQUITY','PX_LAST','20150629','20150630')

AttributeError: 'BCon' object has no attribute 'refDataService'

Error message i am seeing

解决方法

您需要在连接对象上调用 start 方法。

con.start()

bloomberg python
