Union in more than 2 pandas dataframe

Question

select * from table 1 
union
select * from table 2
union 
select * from table 3
un         


        

Answer 1

If I understand well the issue, you are looking for the concat function.

pandas.concat([df1, df2, df3, df4]) should work correctly if the column names are the same for both dataframes.
