Answer 1

您可以使用custom business days：

weekmask = 'Sun Mon Tue Wed Thu'
custombday = pd.offsets.CustomBusinessDay(weekmask=weekmask)

print pd.bdate_range('2016-5-10','2016-5-17', freq=custombday)

DatetimeIndex(['2016-05-10', '2016-05-11', '2016-05-12', '2016-05-15',
               '2016-05-16', '2016-05-17'],
              dtype='datetime64[ns]', freq='C')
