CSV files

CSV files might not be a go-to format for big data, but as a data scientist or developer working in machine learning, you are sure to encounter this format. You might need a mapping of zip codes to latitude/longitude and find this as a CSV file on the internet, or you may be given sales figures from your sales team in a CSV format. In any event, we need to understand how to parse these files.

The main package that we will utilize in parsing CSV files is encoding/csv from Go's standard library. However, we will also discuss a couple of packages that allow us to quickly manipulate or transform CSV data--github.com/kniren/gota/dataframe and go-hep.org/x/hep/csvutil.
