Explanation:
Classes for reading and writing tabular data in CSV format are implemented in the csv module. Without being aware of the specifics of the CSV format that Excel uses, it enables programmers to say things like, "put this data in the format favoured by Excel," or "read data from this file which was generated by Excel." The file is read using the csv. reader() function, which produces an iterable reader object. The contents of each row are then printed using an iterative for loop on the reader object. We are utilizing the csv in the aforementioned example. The file is then read using the csv. reader() method, which produces an iterable reader object. The contents of each row are then printed using an iterative for loop on the reader object.
Thus, the documentation for the csv reader states that a list of strings is returned for each row that was read from the csv file.
