Hello,
I am getting frustrated.
I have been successfully inserting, deleting, etc records with python
and sqlite no problem.
Suddenly the following very simple scrip does not work:
import sqlite3
sPath=r'e:\pythonexamples\aivars2.db'
con=sqlite3.connect(sPath)
cur=con.cursor()

Thats because these are abstract theoretical concepts
at the root of programming but not used much in practice in

Yes it seems you are right. The ActiveState python version I have
installed have sqlite 2.3.2 only. I find it strange.
Why? SQLite is a separate product. Python bundled the then
current version in its standard distribution, but time has moved on.

Hello, Denis,
Please try what sqlite3.version shows on your machine?
Thanks

Hello,
I'm learning to use parsers: trying pyParsing, construct and simpleparse to
have a better overview. I know a bit regular expressions and rather used to
BNF-like formats such as used for specification of languages. But I have never
really employed them personly, so the following may be

The second argument to execute() is a *sequence* of parameter values.

That did the trick! It's worth to remeber.

Kent,
Thanks for the lead. I eventually did something like the Strategy Pattern you
sent. It was so much simpler when I just inherited the functions. I think I
need to redesign the code but for now it works and my boss will be happy.
Thanks

Question 1:

I need to specify that a single, identical, format_code code may be

Not that a there may be several one on a sequence.

Maybe because he *is* the guy who develops pyparsing? ;-)

I also have ActiveState's python (mainly for its very good doc) and
I get:

sqlite3.sqlite_version

Me too with Python 2.5.1 from Activestate.

True, but its pretty rare that timing issues are a reason
for me to choose a data structure - especially if I need
to hand code it! :-)
CREATE TABLE test (name TEXT)
OK, That looks fine.
con=sqlite3.connect(sPath)
cur=con.cursor()
cur.execute(insert into test (name) values (?),sPath)
Try putting the string variable in a tuple:
cur.execute(insert into test (name) values (?), (sPath,) )
That seems to work for me...
Hello tutors,
I'm trying to generate a plot using gnuplot from within a python gui. In
Windows, if after the plot is drawn I use a raw_input string demanding a
'RETURN' be hit, the plot will persist on the screen until the 'RETURN' is
pressed. In *nix, one can use the 'persist' switch to

need fast tests for membership. Failure to choose dict when

When you say crash, what do you mean, exactly?
