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()

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 t

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

Thanks, Alan,
here is a create statement:
CREATE TABLE "test" ("name" TEXT)
And also I would like to thank you for you web page. Classes and OOP
seems to start to make sense to me now slowly after I am reading your
material.

Other than the very different timing characteristics! Python lists are
O(1) for reading or writing a value at an index, O(n) for inserting
and deleting. Linked lists ar

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 aga

Question 1:
format_code := '+' | '-' | '*' | '#'
I need to specify that a single, identical, format_code code may be
repeated.
Not that a there may be several one on a sequence.
format := (format_code)+
would catch '+-', which is wrong. I want only patterns such as '--',
'+++',...

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
'3.3.4'
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! :-)

OK, That looks fine.

Try putting the string variable in a tuple:
cur.execute("insert into test (name) values (?)", (sPath,) )
That seems to work
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 easil

I would guess you commonly choose a dict or set over a list when you
need fast tests for membership. Failure to choose dict when

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