I have 2 dataframes, say all_df and incomplete_df.

I need to compare these 2 dataframes across 3 columns (Fname,Lname, DoB) and find the rows in all_df that are NOT in incomplete_df. I need these rows to then be saved into new dataframe and from there exported to an excel spreadsheet.

This is my first journey into python so any help would be greatly appreciated
