Мне нужно сравнить 2 разных источника и определить все несоответствия для всех IDs
Source_excel
таблица
+-----+-------------+------+----------+
| id | name | City | flag |
+-----+-------------+------+----------+
| 101 | Plate | NY | Ready |
| 102 | Back washer | NY | Sold |
| 103 | Ring | MC | Planning |
| 104 | Glass | NMC | Ready |
| 107 | Cover | PR | Ready |
+-----+-------------+------+----------+
Source_dw
таблица
+-----+----------+------+----------+
| id | name | City | flag |
+-----+----------+------+----------+
| 101 | Plate | NY | Planning |
| 102 | Nut | TN | Expired |
| 103 | Ring | MC | Planning |
| 104 | Top Wire | NY | Ready |
| 105 | Bolt | MC | Expired |
+-----+----------+------+----------+
Ожидаемый результат
+-----+-------------+----------+------------+----------+------------+---------+------------------+
| ID | excel_name | dw_name | excel_flag | dw_flag | excel_city | dw_city | RESULT |
+-----+-------------+----------+------------+----------+------------+---------+------------------+
| 101 | Plate | Plate | Ready | Planning | NY | NY | FLAG_MISMATCH |
| 102 | Back washer | Nut | Sold | Expired | NY | TN | NAME_MISMATCH |
| 102 | Back washer | Nut | Sold | Expired | NY | TN | FLAG_MISMATCH |
| 102 | Back washer | Nut | Sold | Expired | NY | TN | CITY_MISMATCH |
| 103 | Ring | Ring | Planning | Planning | MC | MC | ALL_MATCH |
| 104 | Glass | Top Wire | Ready | Ready | NMC | NY | NAME_MISMATCH |
| 104 | Glass | Top Wire | Ready | Ready | NMC | NY | CITY_MISMATCH |
| 107 | Cover | | Ready | | PR | | MISSING IN DW |
| 105 | | Bolt | | Expired | | MC | MISSING IN EXCEL |
+-----+-------------+----------+------------+----------+------------+---------+------------------+
Я новичок в python, и я пробовал запрос ниже, но он не дал ожидаемого результата.
import pandas as pd
source_excel = pd.read_csv('C:/Mypython/Newyork/excel.csv',encoding = "ISO-8859-1")
source_dw = pd.read_csv('C:/Mypython/Newyork/dw.csv',encoding = "ISO-8859-1")
comparison_result = pd.merge(source_excel,source_dw,on='ID',how='outer',indicator=True)
comparison_result.loc[(comparison_result['_merge'] == 'both') & (name_x != name_y), 'Result'] = 'NAME_MISMATCH'
comparison_result.loc[(comparison_result['_merge'] == 'both') & (city_x != city_y), 'Result'] = 'CITY_MISMATCH'
comparison_result.loc[(comparison_result['_merge'] == 'both') & (flag_x != flag_y), 'Result'] = 'FLAG_MISMATCH'
comparison_result.loc[comparison_result['_merge'] == 'left_only', 'Result'] = 'Missing in dw'
comparison_result.loc[comparison_result['_merge'] == 'right_only', 'Result'] = 'Missing in excel'
comparison_result.loc[comparison_result['_merge'] == 'both', 'Result'] = 'ALL_Match'
csv_column = comparison_result[['ID','name_x','name_y','city_x','city_y','flag_x','flag_y','Result']]
print(csv_column)
Есть ли другой способ Я могу проверить все условия и указать каждое в отдельной строке. Если отдельная строка невозможна, по крайней мере, мне нужен тот же столбец, разделенный всеми несоответствиями. что-то вроде FLAG_MISMATCH,CITY_MISMATCH
