Dear Tutors,
I am looking for some advice. I have some data that has three dimensions to
it. I would like to store it such that one could manipulate (query/ update/
etc.) by dimension - so it would be feasible to ask for all of the data
that shares a value in d1, or iterate over all of the values

This is a problem I have come up against often, and I don't think I have a
good answer, so if anyone else does, I would be glad to hear it!
I would be tempted to generate a 'test data.CSV" file, and run the tests on

Personally I would start with Python 2.7, and start with simple scripts.

understanding of what is already there is very useful.
As to GUI/ Web/ etc. - I think it depends on what you want to do. However,
you will need the basics befo

This caught me out as well for a long time.
As I understand it, csv.reader is a file-reader, which iterates ONCE
over the file. There may be more elegant solutions, but I do:

ifile = open('test.csv', "r")
reader = csv.reader(ifile)
inData = []
