Python Combine multiple data frames

Question

I am trying to combine spreadsheets with a common column name (server/instance) however each spreadsheet doesn't have the same number of rows for the common field. Below I outlined the two data frames. I am trying to figure out if this can be output back to to an excel file or use some type of module to create a python GUI.

Data File 1

sever   database    still running
---------------------------------    
test    database1   TRUE
test    database2   TRUE
test2   database1   FALSE
test2   database3   TRUE

Data File 2 (instance is the same as server from DF1)

Instance app name contact
-------------------------
test     app1     harry
test     app2     sally
test     app3     sally
test2    app1     sally

Final output

server  database    still running   app name    contact
-------------------------------------------------------
test    database1   TRUE            app1        harry
test    database2   TRUE            app2        sally
test                                app3        sally
test2   database1   FALSE           app1        sally
test2   database3   TRUE

I did not understand your logic of merging these spreadsheets, but probably merge from pandas ( https://pandas.pydata.org/pandas-docs/stable/generated/pandas.DataFrame.merge.html ) may be useful. So, firstly you can read these spreadsheets using pandas.read_csv() , then perform merge and in the end save resulting dataframe using pandas.to_csv() .
