如何比較python中的兩個excel工作簿？

Question

我有一個 excel 工作簿 - sheet1 的值：

Names
--------
Aaron  |
Bob    |
Carl   |
Daron  |
Elle   |

我有另一個 excel 工作簿 - sheet2 的值：

Names       Marks
-------------------
Aaron    |   90
Bob      |   89

我希望使用 python 在“標記”列中使用“無標記”將缺失的名稱附加到 sheet2 的工作簿 2 中。

任何人都可以幫忙嗎？

先感謝您

嘗試這個

import pandas as pd

df_list_1 = pd.read_excel (r'data\excel\excel_1.xlsx', sheet_name='Sheet1') # Excel with names
df_list_2 = pd.read_excel (r'data\excel\excel_2.xlsx', sheet_name='Sheet1') # Excel with names and marks

df_list_1 = df_list_1.reset_index()
df_list_2 = df_list_2.reset_index()

df_diff = df_list_1[~df_list_1['Names'].isin(df_list_2['Names'])] # All names not in the second excel with the marks
df_diff = df_diff.fillna("No Marks") # Fill NA with 'no marks', marks on the second excel will be retained
df_list_final = df_list_2.append(df_diff) # Add all names that did not match
df_list_final = df_list_final.drop(['index'], axis=1).reset_index(drop=True) # Remove index column and reindex

print(df_list_final)

輸出

     Names         A         B         C         D
0  Lambrie        90        85       NaN       NaN
1     Wade        70        50       NaN       NaN
2  Jurgens  No Marks  No Marks  No Marks  No Marks
3   Magdel  No Marks  No Marks  No Marks  No Marks
4     Liam        60        50        10        50
