Hi,

Most of the tasks you have to do can be achieved quite easily with the
standard library (except the plotting).

well, the csv module[2] apparently is a good choice for that,

you maybe want to use collections.counter for that[3]. Anyways, I
think matplotlib can handle the counting for you…

this is just iteration over the csv instance you created with your file

I use matplotlib for this purpose, have a look at their gallery[4] to
decide what kind of plot best fits your needs.


I'd recommend to install ipython and start playing around with the
modules I just told you. If you are stuck somewhere read the
documentation properly (it's actually all in there) and come back
again if you cannot come up with a solution.


Hope this helps,
