1. FILE HANDLING Class 12_CSc How to iterate through a CSV file in Python? csvreader is an iterable object. Hence, .next () method returns the current row and advances the iterator to the next row. Since the first row of our csv file contains the headers (or field names), we save them in a list called fields. Now, we iterate through remaining rows using a for loop. Each row is appended to a list called rows.
