I have 3 CSV files. Each has the first column as the (string) names of people, while all the other columns in each dataframe are attributes of that person.
How can I “join” together all three CSV documents to create a single CSV with each row having all the attributes for each unique value of the person’s string name?
The join() function in pandas specifies that I need a multiindex, but I’m confused about what a hierarchical indexing scheme has to do with making a join based on a single index.
