Probably not a good one though. The CSV module is a better approach
since it can take account of all the complexities of CSV files which
your approach would fail on.
For example how do you handle an embedded text field with commas in it?
Or newlines? Or a quoted field containing quotes?
When a module exists in the standard library its nearly always worth
using it. Somebody has taken the time to write it, test it and submit it
precisely because the simple approach doesn't work reliably.
