Python to C++ in a pickle
by Larry Whitley April 2, 2015

April 2, 2015

I'd like to pickle an object in python and unpickle it in C++. The object in question is a python dictionary so it will have to go into a C++ map. Has someone done this and is willing to share? Or, is the cPickle source available on the web somewhere? Larry

Creating interactive command-line Python app?
by planetthoughtful Dec. 18, 2014

Dec. 18, 2014

Hello All, Newbie to Python, and I'm wondering if it's possible to create a Python console app that prompts for further input on the command line when run (in Windows XP, if that's important)? I've tried Googling, but the results are overwhelmingly about interactive Python environments (IPython etc etc), instead of how to achieve prompting at the command line when running your own Python app. Any help appreciated! Much warmth, planetthoughtful

New B question -- Need help with win32net.NetGroupAddUser. I used Mark Hammond sample code to create a new user from his book Python Programming on Win32. I then added one line to add the newuser to a group. def CreateUserAndShare(userName, fullName): homeDir = "%s\\%s" % (serverName, userName) # Create user data in information level 3 (PyUSER_INFO_3) format. userData = {} userData['name'] = userName userData['full_name'] = fullName userData['password'] = userName userData['flags'] = win32netcon.UF_NORMAL_ACCOUNT | win32netcon.UF_SCRIPT userData['priv'] = win32netcon.USER_PRIV_USER userData['home_dir'] = homeDir userData['home_dir_drive'] = "P:" userData['primary_group_id'] = ntsecuritycon.DOMAIN_GROUP_RID_USERS userData['password_expired'] = 1 # User must change password next logon. # Create the user win32net.NetUserAdd(serverName, 3, userData) win32net.NetGroupAddUser(serverName, "Administrator", userName) This is my error: pywintypes.api_error: (2220, 'NetGroupAddUser', 'The group name could not be found.') What should I be using for the groupname parameter, I've tried them all, Administrator, Guests, Users ext.... Any help will be greatly appreciated. Thanks, kc

President Bush Meets Pope Before Heading to Paris
by vaticans.org Nov. 2, 2014

Nov. 2, 2014

U.S. President George Bush has met with Pope Benedict at the Vatican, as he continues his week-long European trip. After his talks with the pontiff, Mr. Bush was traveling to Paris, France, where he is to give a speech later Friday on the strong relationship between the U.S. and Europe. U.S. National Security Advisor Stephen Hadley said Mr. Bush will urge European leaders to work even more closely with the U.S. to help bring peace to the Middle East. Mr. Hadley said the trans-Atlantic relationship has been strengthened by the current leaders in Italy, Britain, Germany, and France. The White House says Mr. Bush's speech will also commemorate the 60th anniversary of the Marshall Plan - the U.S. aid program that helped rebuild Europe after the devastation caused by World War II. The president and Mrs. Bush are then scheduled to have dinner with the French president and Mrs. Sarkozy at the Elysee Palace. Mr. Bush and Mr. Sarkozy hold formal talks on Saturday. On Thursday President Bush met with Italian Prime Minister Silvio Berlusconi and the two leaders agreed to to work together on trying to convince Iran to give up its uranium enrichment program. Mr. Berlusconi said Italy has a trading relation with Iran and knows that country from the inside. President Bush said he will consider Italy's request to join the five permanent U.N. Security Council members and Germany in working on the Iran nuclear issue. But Mr. Hadley said it is always a problem when a country's commercial ties clashes with its national security requirements. Mr. Bush's European trip will also take him to Britain and Northern Ireland. Earlier, he stopped in Germany and attended the annual U.S.- European Union summit in Slovenia. http://www.vaticans.org/index.php?/archives/1175-Pope-Benedict-XVI-hosted-U…

Perl Template Toolkit: Now in spicy new Python flavor
by eefacm＠gmail.com Oct. 8, 2014

Oct. 8, 2014

I'd like to inform the Python community that the powerful and popular Template Toolkit system, previously available only in its original Perl implementation, is now also available in a beta Python implementation: http://tt2.org/python/index.html I created this port both as a fun programming project, and for use in environments where Perl is not available, for reasons technical, cultural, or otherwise. The extensive Perl test suites have also been ported, and most templates require no or very little modification. Discussion of the Python implementation should be conducted on the main Template Toolkit developer mailing list; see the site above for details.

Just had to change ´file´ to ´open´ for my Python 2.1. Adding the method ´flush(self)´ to Writer helped to get my ´sys.stdout.flush()´ to work. Thanks also to two inches (previous post). Mike

Python OPC -wrapper for data collection, anyone seen it ?
by pekka niiranen March 24, 2014

March 24, 2014

Has anybody seen OPC -wrapper done in python ? In industry OPC -servers are breaking thru. It is a microsoft based technoloqy to gather process information. Many Control System manufacturers have their own OPC -servers. There exists a visual basic wrapper -library so that one write VB - programs to enquire data from OPC -server.Wrapper done to python would be cool. Mark Hammond was not interested, but I am not giving up yet... -pekka-
