Answer 1

Change the line

inner_join = pd.merge(df1,df2,left_on='BILL_CONTROL_NUMBER',right_on='Control_number')

to this

inner_join = pd.merge(df1,df2[['Name','Control_number']],left_on='BILL_CONTROL_NUMBER',right_on='Control_number')

You can specify columns you want using [['column1','column2','etc..']]
