How to Compare 2 DataFrame which different Column Names( Columns are in same Sequence) in Python

Question

The requirement is to compare 2 dataframe(dataset) both having different header. Basically I am querying database(HANA) table and comparing its output with the output of a SQL code as data testing

Ex

df1:

customerNo  City   Amount
C1          ABC     100
C2          XYZ     50

df2:

customer   Place   Amount
C1          ABC     100
C2          PQR     40

Although column names are different but they are in the correct order. Is there a way to compare dataset just based on column orders?

I tried datacompy.Compare(df1,df2, on_index=True) but its not working.

Answer 1

Try renaming the columns and then running your compare tests. An example for renaming columns:

df2 = df2.rename(columns = {'customer':'customerNo','Place':'city','Amount':'Amount'})
