What is the difference between reader and DictReader function?

What is the difference between reader() and DictReader() function?…Solution.

csv. Reader() allows you to access CSV data using indexes and is ideal for simple CSV files. csv. DictReader() on the other hand is friendlier and easy to use, especially when working with large CSV files.
