使用csv中的pandas.dataframe创建字典

Question

import pandas as pd
#from pandas import DataFrame 

import datetime
import pandas.io.data
from pandas_datareader import data, wb

df = pd.read_csv('testfile.csv')
grouped = df.groupby(['Arrival','Date', 'Time'])
for name, group in grouped:
    print (name)
    print(group)

AuthorID    Arrival     Departure    Date            Time
1922        Paris       New York    09/12/10    10:00:00 AM
1002        Los Angeles California  02/12/09    09:00:00 AM
1901        Paris       Nigeria     02/09/09    10:00:00 AM
1922        Paris       New York    02/09/09    10:00:00 AM
1002        Paris       California  09/12/10    10:00:00 AM
1099        Paris       China       02/09/09    10:00:00 AM
1901        Los Angeles Paris       02/12/09    09:00:00 AM

我想使用到达和离开创建字典，然后查找作者ID，而不是在特定日期和时间具有相同的到达或离开。
