First off, full disclosure: This is going towards a uni assignment, so I don't want to receive code.  :).  I'm more looking for approaches; I'm very new to python, having read a book but not yet written any code.

            Hi all
I've just implemented some code that emails a bunch of our clients with a CSV file attachment.
Some (not many) have got back to us complaining that they don't get an attachment at all - just the CSV text inside the body of the email. Most however are fine.
I suspect that it's different mail clients that are treating the attachm...
            
           
          
            
            Dear all,
Does anyone have some advise how to read a comma separated data file into matlab? The simple solutions (like dlmread, fscanf) do not seem to work, as there are multiple (10) lines of header information. The closest I got to a solution is:
C=textscan(datafile)
G=cell2mat(C{1,1}(34:endoffile)}) //34 is the line the data starts

            Python provides csv.DictWriter for outputting CSV to a file.
What is the simplest way to output CSV to a string or to stdout?
For example, given a 2D array like this:
[["a b c", "1,2,3"],
 ["i \"comma-heart\" you", "i \",heart\" u, too"]]
return the following string:
"a b c, \"1, 2, 3\"\n\"i \"\"comma-heart\"\" you\", \"i \"\",heart...
            
           
          
            
            I'm trying to pick up Python. As part of the learning process I'm porting a project I wrote in Java to Python. I'm at a section now where I have a list of CSV headers of the form:
headers = [a, b, c, d, e, .....]
and separate lists of groups that these headers should be broken up into, e.g.:
headers_for_list_a = [b, c, e, ...]
header...
            
           
          
            
            Consider the following 2 by 2 array:
x = {{"a b c", "1,2,3"}, {"i \"comma-heart\" you", "i \",heart\" u, too"}}
If we Export that to CSV and then Import it again we don't get the same thing back:
Import[Export["tmp.csv", d]]
Looking at tmp.csv it's clear that the Export didn't work, since the quotes are not escaped properly.

I am dealing with a "large" measurement data, approximately 30K key-value
pairs. The measurements have number of iterations. After each iteration a
datafile (non-csv) with 30K kay-value pairs is created. I want to somehow
