Comparing two excel files with Python based on changes

+3
−1

I have two tables:

Table1:

Name Description Amount
123 Description123 123
456 Description456 456
789 Description789 666
101 Description777 101
133 Description133 133

Table2:

Name Description Amount
456 Description456 456
789 Description789 789
101 Description101 101
123 Description123 123
102 Description102 102

I need to find the difference in Table1 compared it from Table2. The connection between these 2 excel files will be the column Name. Expected output is if something is changed in Table 2 the data must be used from Table 2 and if there is new rows from Table 2 they must be added to the final result. If nothing is also changed or Table 2 doesn't have any data for specific Name from Table 1 like 133 the rows also need to be added to the final result.

Expected output:

Name Description Amount
123 Description123 123
456 Description456 456
789 Description789 789
101 Description101 101
102 Description102 102
133 Description133 133

Thanks in advance!

Edit1: I struggle to find the solution. I understand how to compare each rows in the excel files, but they need to have exactly the same order in Name column. I don't know how to do it if there is no order like this specific case above.
