adding python engine into c++ application
by griwes Jan. 1, 2010

Jan. 1, 2010

Hello, I am going to write an application in C++, application which should be easy to extend by scripts. I chose python for script language in this application. I'd like to have own API for python. And here the question arises: how do I implement a python engine within an application written in C++? Sory for any mistakes, english isn't my native language ;)

Not Incrementing
by Victor Subervi Jan. 1, 2010

Jan. 1, 2010

Hi; This "pseudo-code" snippet was given to me by Dennis on this list (whose last name escapes me): def printTree(allTrees, level=0): tree = [] for aTree in allTrees: for name in sorted(aTree.keys()): tree.append("%s%s" % ("\t" * level, name)) printTree(aTree[name], level + 1) return tree The code returns all the categories ("name") just fine. It doesn't, however, increment level. I know from my tests that printTree is only called twice (once for each store) and about half a dozen times recursively within one of those stores. Why doesn't this increment? Full code follows. TIA, beno #!/usr/bin/python import sys,os sys.path.append(os.getcwd()) import MySQLdb from login import login import re, string def printTree(allTrees, level=0): tree = [] for aTree in allTrees: for name in sorted(aTree.keys()): tree.append("%s%s" % ("\t" * level, name)) printTree(aTree[name], level + 1) print '1' return tree def expand(fetched): aDict = {} for (name, ) in fetched: aDict[name] = {} return aDict def getChildren(levelDict, store, level = 0): user, passwd, db, host = login() db = MySQLdb.connect(host, user, passwd, db) cursor = db.cursor() MAXLEVEL = 7 if level > MAXLEVEL: return #possibly the data has a cycle/loop for name, data in levelDict.iteritems(): sql = '''select * from categories%s as c inner join categoriesRelationships%s as r on c.ID = r.Child inner join categories%s as p on r.Parent = p.ID where p.Category = "%s"''' % (store[0].upper() + store[1:], store[0].upper() + store[1:], store[0].upper() + store[1:], name) cursor.execute(sql) levelDict[name] = expand(cursor.fetchall()) # recursive call to do next level getChildren(levelDict[name], level + 1) # no data return as we are mutating dictionaries in place def catTree(allStores): user, passwd, db, host = login() db = MySQLdb.connect(host, user, passwd, db) cursor = db.cursor() finalTrees = [] returnFlag = '' for store in allStores: allTrees = [] sql = 'create table if not exists categories%s (ID int(3) unsigned primary key auto_increment, Category varchar(40), Parent varchar(40));' % (store[0].upper() + store[1:]) cursor.execute(sql) sql = 'create table if not exists categoriesRelationships%s (ID integer auto_increment primary key, Parent integer not null, foreign key (Parent) references categories%s (ID), Child integer not null, foreign key (Child) references categories%s (ID), check (Parent <> Child) );' % (store[0].upper() + store[1:], store[0].upper() + store[1:], store[0].upper() + store[1:]) cursor.execute(sql) cursor.execute('select Category, Parent from categories%s;' % (store[0].upper() + store[1:])) data = cursor.fetchall() cursor.execute('select Category from categories%s order by Parent, ID;' % (store[0].upper() + store[1:])) Categories = [itm[0] for itm in cursor] #untuple single column if len(Categories) > 0: cursor.execute('select Parent from categories%s order by Parent, ID;' % (store[0].upper() + store[1:])) Parents = [itm[0] for itm in cursor] MAXLEVEL = 15 # get top level cursor.execute('select category from categories%s order by Category;' % (store[0].upper() + store[1:])) theTree = expand(cursor.fetchall()) getChildren(theTree, store) db.commit() allTrees.append(theTree) returnFlag = 'gotStuff' else: returnFlag = 'gotNoStuff' finalTrees.append(printTree(allTrees)) if returnFlag == 'gotStuff': return finalTrees else: return '' -- The Logos has come to bear http://logos.13gems.com/

Cookies
by Victor Subervi Dec. 31, 2009

Dec. 31, 2009

Hi; I have these lines: cookie = os.environ.get('HTTP_COOKIE') if not cookie: cookie = Cookie.SimpleCookie() cExpires, cPath, cComment, cDomain, cMaxAge, cVersion = myCookie() cookie['lastvisit'] = str(time.time()) cookie['lastvisit']['expires'] = cExpires cookie['lastvisit']['path'] = cPath cookie['lastvisit']['comment'] = cComment cookie['lastvisit']['domain'] = cDomain cookie['lastvisit']['max-age'] = cMaxAge cookie['lastvisit']['version'] = cVersion cookieFlag = 'new' else: cookie = Cookie.SimpleCookie(cookie) cookieFlag = 'old' print '''Content-Type: text/html\r\n <!DOCTYPE html PUBLIC "-//W3C//DTD HTML 4.01 Transitional//EN"> <html> ''' print cookieFlag cookieFlag prints 'new'. Every time. Even when I refresh. I've imported Cookie. I've followed the tutorials :-} I've already been through my problem with trying to find the cookies on this computer. The fact that I'm using gmail is proof that cookies are enabled. I have also tried: cookie = os.environ.has_key('HTTP_COOKIE') Please advise. beno

multiprocessing module
by makobu Dec. 31, 2009

Dec. 31, 2009

I have a function that makes two subprocess.Popen() calls on a file. I have 8 cores. I need 8 instances of that function running in parallel at any given time till all the files are worked on. Can the multiprocessing module do this? If so, whats the best method? A technical overview of how the multiprocessing module actually works would also be really helpful. regards, mak.

mod, modulo and % under 2.4 and 2.5
by W. eWatson Dec. 31, 2009

Dec. 31, 2009

About a year ago, I wrote a program that used mod() for modulo under 2.5. Apparently, % is also acceptable, but the program works quite well. I turned the program over to someone who is using 2.4, and apparently 2.4 knows nothing about mod(). Out of curiosity, what library is mod(a,b)(two args) in? It doesn't seem to be in numpy. It seems to be built-in. If so, why isn't it both 2.4 and 2.5?

Re: Dangerous behavior of list(generator)

You can provide a sentinel and test for that instead of using try...except: >>> from random import randrange >>> from functools import partial >>> def g(): ... return iter(partial(randrange, 3), 2) ... >>> next(g(), "empty") 1 >>> next(g(), "empty") 1 >>> next(g(), "empty") 'empty' >>> next(g(), "empty") 'empty' >>> next(g(), "empty") 'empty' >>> next(g(), "empty") 0 Peter
