Question

我正在尝试跟踪一组交货的移动历史。我有两个数据框-第一个是历史记录开始之前每个交付物品的最后一个已知位置：

java.lang.IllegalStateException: Could not evaluate condition on org.springframework.boot.actuate.autoconfigure.EndpointWebMvcAutoConfiguration$EndpointWebMvcConfiguration due to org/springframework/web/servlet/config/annotation/AsyncSupportConfigurer not found. Make sure your own configuration does not rely on that class. This can also happen if you are @ComponentScanning a springframework package (e.g. if you put a @ComponentScan in the default package by mistake)

    etc...

接下来是交货历史记录：

prior_location = pd.DataFrame([
    {'Equip': 'A-1', 'Date': '2019-07-15', 'Location': '123 Main St.'},
    {'Equip': 'A-2', 'Date': '2019-07-17', 'Location': '15 First Ave.'}
])

我的目标是为每次交付生成一个带有deliveries = pd.DataFrame([ {'Equip': 'A-1', 'Date': '2019-08-01', 'DeliveredTo': '191 Long Rd.'}, {'Equip': 'A-1', 'Date': '2019-08-03', 'DeliveredTo': '582 Pleasant Court'}, {'Equip': 'A-1', 'Date': '2019-08-04', 'DeliveredTo': 'SHOP'}, {'Equip': 'A-2', 'Date': '2019-07-30', 'DeliveredTo': 'YARD'}, {'Equip': 'A-2', 'Date': '2019-08-01', 'DeliveredTo': '191 Long Rd.'}, {'Equip': 'A-2', 'Date': '2019-08-05', 'DeliveredTo': '15 Lake Drive'} ])和PickedUpFrom列的数据框。例如-最终数据框应类似于：

DeliveredTo

请注意，每台设备的第一个条目history = pd.DataFrame([ {'Equip': 'A-1', 'Date': '2019-08-01', 'PickedUpFrom': '123 Main St.', 'DeliveredTo': '191 Long Rd.'}, {'Equip': 'A-1', 'Date': '2019-08-03', 'PickedUpFrom': '191 Long Rd.', 'DeliveredTo': '582 Pleasant Court'}, {'Equip': 'A-1', 'Date': '2019-08-04', 'PickedUpFrom': '582 Pleasant Court', 'DeliveredTo': 'SHOP'}, {'Equip': 'A-2', 'Date': '2019-07-30', 'PickedUpFrom': '123 Main St.', 'DeliveredTo': 'YARD'}, {'Equip': 'A-2', 'Date': '2019-08-03', 'PickedUpFrom': 'YARD', 'DeliveredTo': '191 Long Rd.'}, {'Equip': 'A-2', 'Date': '2019-08-04', 'PickedUpFrom': '15 First Ave.', 'DeliveredTo': '15 Lake Drive'}, ])来自PickedUpFrom表，随后的是上一行（对于该设备）prior_location。 / p>

任何想办法做到这一点的方法（我的实际数据集有数千台设备）。

有两件事要注意-每个日期每台设备只有一次交货（因此DeliveredTo在给定日期仅在一个位置）。另外，保证A-1数据帧的位置在交货数据帧的第一个元素之前。

Answer 1

这里是首先groupby + shift，然后是fillna和prior_location的一种方式

deliveries['PickedUpFrom']=deliveries.groupby('Equip').DeliveredTo.shift()
s=prior_location.set_index('Equip')['Location'].reindex(deliveries.Equip).values
deliveries['PickedUpFrom'].fillna(pd.Series(s,index=deliveries.index),inplace=True)
deliveries
Out[51]: 
  Equip        Date         DeliveredTo        PickedUpFrom
0   A-1  2019-08-01        191 Long Rd.        123 Main St.
1   A-1  2019-08-03  582 Pleasant Court        191 Long Rd.
2   A-1  2019-08-04                SHOP  582 Pleasant Court
3   A-2  2019-07-30                YARD       15 First Ave.
4   A-2  2019-08-01        191 Long Rd.                YARD
5   A-2  2019-08-05       15 Lake Drive        191 Long Rd.
