我正在尝试从 Pandas datetools 调用一个模块，但是我收到一个错误，即 mofule 对象没有我正在调用的名称的属性。想知道是否有人可以对这个问题有所了解。以下是我尝试使用的代码：
import blpapi
import pandas as pd
from tia.bbg import LocalTerminal
import datetime
from pandas import datetools
sid = 'BKLN US EQUITY'
events = ['TRADE','AT_TRADE']
dt = pd.datetools.BDAY(-1).apply(pd.datetime.now())
And here is the error I am facing:
这是我面临的错误：
Traceback (most recent call last):
File "C:\bb_test.py", line 14, in <module>
dt = pd.datetools.BDAY(-1).apply(pd.datetime.now())
File "C:\Python27\lib\site-packages\pandas\util\_depr_module.py", line 61, in
__getattr__
obj = getattr(deprmodule, name)
AttributeError: 'module' object has no attribute 'BDAY'

First, consider that pandas datetoolsis deprecated and will be removed in future releases.
首先，考虑到 pandasdatetools已被弃用并将在未来版本中删除。
But if you insist on using it, you need to pass timedeltaobject to bdayfunction like follows:
但是如果你坚持使用它，你需要像下面这样将timedelta对象传递给bday函数：
import pandas as pd
from pandas import datetools
import datetime
from datetime import timedelta
# Constructing timedelta object
d = timedelta(days=-1)
# passing it to bday
pd.datetools.bday(d).apply(pd.datetime.now())
