熊猫假期到带有假期名称的数据框

Question

到目前为止，这是我的代码：

year = 2012
start = datetime.date(year, 1, 1)
end = start + pd.offsets.MonthEnd(72)

class FrBusinessCalendar(AbstractHolidayCalendar):
""" Custom Holiday calendar 
"""
rules = [
    Holiday('New Years Day', month=1, day=1),
    #USThanksgivingDay,
    Holiday('Fourth Of July', month=7, day=4),
    Holiday('Thanksgiving', month=11, day=1, offset=DateOffset(weekday=TH(4))),
    Holiday('Black Friday', month=11, day=1, offset=pd.DateOffset(weekday=FR(4))),
    Holiday("Cyber Monday", month=11, day=1, offset=[pd.DateOffset(weekday=SA(4)), pd.DateOffset(2)]),
    Holiday('Christmas Day', month=12, day=25)
]

cal = FrBusinessCalendar()
# Getting the holidays (off-days) between two dates
cal.holidays(start=start, end=end)

现在，我要做的是将所有这些日期放入一个数据框，其中假期名称为一列，日期为另一列。 所以以我的例子

date           holiday
2012-01-01     New Years Day
2012-07-04     Fourth Of July
2012-11-22     Thanksgiving
....etc

Answer 1

我们可以使用cal.holidays(return_name=True)方法：

In [85]: holidays = cal.holidays(start=start, end=end, return_name=True)

In [86]: pd.options.display.max_rows = 20

In [87]: holidays
Out[87]:
2012-01-01     New Years Day
2012-07-04    Fourth Of July
2012-11-22      Thanksgiving
2012-11-23      Black Friday
2012-11-26      Cyber Monday
2012-12-25     Christmas Day
2013-01-01     New Years Day
2013-07-04    Fourth Of July
2013-11-22      Black Friday
2013-11-25      Cyber Monday
                   ...
2016-11-24      Thanksgiving
2016-11-25      Black Friday

2017-11-27      Cyber Monday
2017-12-25     Christmas Day

或您想要的格式：

In [88]: holidays.reset_index(name='holiday').rename(columns={'index':'date'})
Out[88]:
         date         holiday
0  2012-01-01   New Years Day
