    Hi I have 3 csv files with a list of 5 items in each.
    rainfall in mm, duration time,time of day,wind speed, date.
    I am trying to compare the files. cutting out items in list list. ie:-
    first file (rainfall2012.csv)rainfall, duration,time of day,wind speed,date.
    first file (rainfall2013.csv)rainfall, duration,time of day,wind speed,date.
    I would like to pick out maybe rainfalls and duration's and measure against say years.
    I would like to very the items from the rows.
    could you please advise me where i can find such information. or book, textbook.

  2. Hi I have 3 csv files with a list of 5 items in each.
    How about we help you here..

    So if you want to compare by year, you want to read all the rows in and perform
    some math, because I can't help myself, I push this into sqlite at least but that's
    probably overkill for you (besides the limitless benefits:)). You want to store some
    state while you iterate over each row in the csv, appending data, then finally performing
    some statistical math on the collection.

    You will do this for each file, then finally aggregate your results.

    How is this a Python question?

    There is a standard module included with Python for reading CSV files.
    Would you like to know how to use that? You can find documentation on
    it here:
