CSVファイルを処理するには

When working with CSV files in Python, how can you efficiently convert the data into a format that allows you to access information by column names (like keys in a dictionary)?There's no direct way to achieve this; CSV files remain as lists of lists.You need to manually write code to loop through each row and create dictionaries yourself.The standard csv.reader function automatically converts CSV data into dictionaries.Use the csv.DictReader class from the csv module.
