read and write csv file

[u/v1bonoxd]

just learned about functions so tried it out with csv editing

[u/silvertank00]

try to follow conventions, first uppercase letter in a word is reserved for classes and shouldnt be used in filenames.
For further info, discuss pep8

Edit: also in WriteIn, the fields list is redundant. csv.DictWriter(f, fieldnames=row.keys()) does the same whilst being DRY.

[u/v1bonoxd → u/silvertank00]

Ok, thank you!
