Update: [Jython-users] Importing csv.pyd in Jython

[Updike, C. <Cla...@jh...>]

Doh!  I forgot what the 'c' in csv stood for (I am always working 
with tab delimited formats sent from Excel via http).  In case it's not 
obvious, just replace the "\t" below with a "," and it will work 
for csv.

I do a lot of work with csv formats and have always just used plain 
old code to do it.  But here are some helper functions you can easily 
customize and use with files:

>>> def list2csv(l):
...    return "\n".join(["\t".join([str(cell) for cell in row]) for row in
l])
...
>>> def csv2list(csvString):
...    return [row.split("\t") for row in csvString.split("\n")]
...
>>> l = [[1,2,3],[4,5,6]]
>>> print list2csv(l)
1       2       3
4       5       6
>>> print csv2list(list2csv(l))
[['1', '2', '3'], ['4', '5', '6']]
>>> l = [['a','b','c'],['d','e','f']]
>>> csv2list(list2csv(l)) == l
1

list2csv is converting everything to strings which may be nugatory if you're

only working with lists of strings.  If list comprehension one-liners are 
bothersome to you, you can always unroll them into 
for loops.

Subject: [Jython-users] Importing csv.pyd in Jython

Hi

I wish to read csv files from within Jython.  Unfortunately, there is a csv 
module in Python 2.3 which Jython 2.1 does support.  Rock on Jython 2.2!

Meanwhile, I found a compiled csv python module from 
<http://www.object-craft.com.au/projects/csv>.  A precompiled csv.pyd 
file is available for download for Python 2.1 and for Python 2.2.  I have 
tried importing it in my Jython file, however, Jython does not 
appear to recognise it.

Any ideas?
