This also gives you a bit of control regarding how escaping is done, and
other knobs dials to twiddle if you need. Additionally, if you have more
than one string to process coming from an iterable source (such as a file),
you can just pass that iterator to csv.reader() instead of concocting a
one-element list.
Thx, I think this will work for what I want.

Hmm. When I put csv.reader in a class:
import csv
class IS_LIST():
def __init__(self, format='', error_message='must be a list!'):
self.format = format
self.error_message = error_message
def __call__(self, value):
try:
if value=='[]' or value=='':
value=[]
else:
no_brackets = value[1:-1] # s.strip(' \t[]')
c = csv.reader([no_brackets], quotechar=')
value=c.next()
return (value, None)
except:
return (value, self.error_message)
def formatter(self, value):
return value
I get an error (when I take the try out):
AttributeError: 'function' object has no attribute 'reader'
Why?

string to list when the contents is a list
I have been trying to create a list form a string. The string will be
a list (this is the contents will look like a list). i.e. [] or
['a','b']
The [] is simple since I can just check if value == [] then return []
But with ['a','b'] I have tried and get:
a=['a','b']
b=a[1:-1].split(',')
returns
[ 'a' , 'b' ]
when I want it to return ['a','b'].
How can I do this?
thx,

how to conditionally add a dict in-line

What a mess. How can you read it?
How do I do something like this:
vars={'_page':i, if request.vars._query not None then insert this
key/value pair ('_query':request.vars._query) else insert nothing }
vars = {'_page': i}
if request.vars._query is not None:
vars['_query'] = request.vars._query
Could this be:
vars = {'_page': i}
if request.vars._query:
vars['_query'] = request.vars._query
See how simple and clear things are when you give up the insistence on
making everything a one-liner?

parsing text from a file
If I read a windows registry file with a line like this:
{C15039B5-C47C-47BD-A698-A462F4148F52}=v2.0|Action=Allow|Active=TRUE|Dir=In|Protocol=6|Profile=Public|App=C:\\Program
Files\\LANDesk\\LDClient\\tmcsvc.exe|Name=LANDesk Targeted
Multicast|Edge=FALSE|
with this code:
f=open('fwrules.reg2.txt')
for s in f:
if s.find('LANDesk') 0:
print s,
LANDesk is not found.
Also this does not work:
for s in f:
try:
i=s.index('L')
print s[i:i+7]
except:
pass
all it prints is LAND
how do I find LANDesk in a string like this. is the \\ messing things up?
