Nice tutorial, thanks for the info. Can you run through this process with more than 2 separate files?

[@learnerea]

Thanks for the kind words George To answer your question, consider you have three dataframes namely - cust, tranTime and tranValue To join all these three(here I'm doing the default join which is inner but you can change that as suggested in the video), you can use the below syntax - merged = pd.merge(cust,tranTime,on='Invoice ID').merge(tranVal,on='Invoice ID')
