Question

The following lines give AttributeError: 'module' object has no attribute 'bdate_range'.

I think this might have something to do with a circular reference; but, I don’t know where.

import pandas as pd

times = pd.bdate_range(start=pd.datetime(2012,11,14,0,0,0),
                       end=pd.datetime(2012,11,17,0,0,0),
                       freq='10T')

This is the traceback:

AttributeError              Traceback (most recent call last)
<ipython-input-3-1eb62db1246d> in <module>()
       4 
       5 
 ----> 6 times = pd.bdate_range(start=pd.datetime(2012,11,14,0,0,0),end=pd.datetime(2012,11,17,0,0,0),
 freq='10T')
       7 filtered_times = [x for x in times if x.time() >= time(9,30) and x.time() <= time(16,20)]
       8 prices = randn(len(filtered_times))

Answer 1

The bdate_range function was introduced in pandas version 0.8.0. So this ought to work fine if you upgrade to pandas >= 0.8.0 (and I would recommend using the latest stable release).

Note: The pandas website allows you to search the docs by version number (select your versions’s docs on the right-hand side of the main page). In version 0.7.3 there are no search results for bdate_range.
