我有一個資料框，我想將假期作為二進制檔案。但是，我可以將它們放在字串中。此外，似乎在某些日子里，有一個錯誤。比如，2019-01-01 應該是假期。這是我的資料示例。你能幫我解決這個問題嗎？
import pandas as pd
import numpy as np
from pandas.tseries.holiday import USFederalHolidayCalendar as calendar
df = pd.DataFrame()
df['date'] = [ '2019-01-01', '2015-07-03', '2019-01-12', '2019-01-13']
df['c1'] = [ 4, 3, 8, 5]
df['c2'] = [1 , 3, 11, 2]
df
cal = calendar()
holidays = cal.holidays(start=df['date'].min(), end=df['date'].max())
df['Holiday'] = df['date'].isin(holidays)
df
uj5u.com熱心網友回復：
只需將行更改為：
df['Holiday'] = df.index.get_level_values(0).isin(holidays).astype(int)
