有没有更好/更直接的方法来计算这个比以下？
# 1. Set up the start and end date for which you want to calculate the
# number of business days excluding holidays.
start_date = '01JAN1986'
end_date = '31DEC1987'
start_date = datetime.datetime.strptime(start_date, '%d%b%Y')
end_date = datetime.datetime.strptime(end_date, '%d%b%Y')
# 2. Generate a list of holidays over this period
from pandas.tseries.holiday import USFederalHolidayCalendar
calendar = USFederalHolidayCalendar()
holidays = calendar.holidays(start_date, end_date)
holidays
这给出了一个pandas.tseries.index.DatetimeIndex
DatetimeIndex(['1986-01-01', '1986-01-20', '1986-02-17', '1986-05-26',
'1986-07-04', '1986-09-01', '1986-10-13', '1986-11-11',
'1986-11-27', '1986-12-25', '1987-01-01', '1987-01-19',
'1987-02-16', '1987-05-25', '1987-07-03', '1987-09-07',
'1987-10-12', '1987-11-11', '1987-11-26', …在终端中安装 matlab python 包后，使用：
cd "matlabroot\extern\engines\python"
python setup.py install
尝试运行它时，出现段错误：

>>> import matlab.engine

但是，我可以通过设置 DYLD_LIBRARY_PATH 来解决这个问题，然后 matlab.engine 就可以工作：
:~$ export DYLD_LIBRARY_PATH=/System/Library/Frameworks/Python.framework/Versions/Current/lib:$DYLD_LIBRARY_PATH
:~$ python
