Accessing csv header white space and case insensitive

Question

I\'m overriding the csv.Dictreader.fieldnames property like the following to read all headers from csv files without white space and in lower case.

Answer 1

You'll have to do it in two steps:

1. Create your dict specialisation with a __getitem__ method that applies the .strip().lower() to the its key parameter.
2. Override __next__ on your MyDictReader specialised class to return one of your special dictionaries initialised with the dictionary returned by the csv.DictReader superclass's __next__ method.
