I want to pickle (very long) strings and save them in a sqlite db.
Why?
Why not just store the string in the database?
If that turns out to be a problem then think about other
options - like splitting it into chunks say?
But until you know you have a problem don't
Ok -- realized my "solution" incorrectly strips white space from
multiword strings:

So here are some more gymnastics to get the correct result:
In [105]: newlist
Out[105]: ['a2345b.', '|', 'a45453b.', 'a325643b.', 'a435643b.', '|']
In [109]
As usual, Kent Johnson has swooped in an untangled the mess with a
clear explanation.
By the time a regex gets this complicated, I typically start thinking
of ways to simplify or avoid them altogether.
Below is the code I came up with. It goes through some gymnastics and
can surely stand improvem

Hi Vince
That's terrific! Once a string is compressed with gzip.zlib does it make a
difference whether it is stored it in a TEXT or BLOB column?

Hello, I am accessing a Pervasive SQL data source using odbc and I'm
having this trouble:
import dbi
import odbc
# the first execute works
pnumber = '09F153'
wh = '00'
qty = 3
myconn = odbc.odbc('DSN=MKPT01')

mycursor.execute("""

apologies -- I just reread your post and appears you also want to
capture the dot after each "b" ( "b." )
In that case, you need to update the pattern to match for the dot. But
because the dot is itself a metacharacter, you have to escape it with
a backslash:
In [23]: re.findall(r'a\w+b\.',text)

That helps a lot. It was stupid of me to not compare the output from
the two functions.
The second for loop is actually skiiping over some of the values and
hence it takes longer to run when the "plst" is generated.

Hi!
I am trying to split some lists out of a single text file, and I am
having a hard time. I have reduced the problem to the following one:
text = "a2345b. f325. a45453b. a325643b. a435643b. g234324b."
Of this line of text, I want to take out strings where all words start
with a, end with "b.".
Pickle is more for storing complex objects (arrays, dict, etc). pickling a
string makes it bigger.
I have stored large text chunks in text and/or blob columns compressed with
gzip.zlib.compress and extracted with gzip.zlib.decompress
Comparison:
import cPickle as Pickle
import gzip
x = "asdfasd
I want to pickle (very long) strings and save them in a sqlite db. The plan is
to use pickle dumps() to turn a string into a pickle object and store it in
sqlite. After reading the string back from the sqlite db, use pickle loads()
to turn back into original string.
