Postgresql+Python -tutorial?
by Olli Rajala Feb. 11, 2006

Feb. 11, 2006

Hi! I've been using MySQL up this day, but would like to convert my program to use Postgresql. There seems to be awful lots of tutorials for MySQL+Python, but not so many for Postgresql+Python. Where should I start? I'm not very good at database things, but have written some little programs with MySQL+Python/Php/Java. So, if you have some good tutorials or something else info, I'd be glad to know! Oh, I can install additional modules, but it would be great if Ubuntu had them... Thanks! -- Olli Rajala <>< Tampere, Finland http://www.students.tut.fi/~rajala37/ "In theory, Theory and Practice should be the same. But in practice, they aren't." - Murphy's Proverbs

Copy files
by David Holland Feb. 6, 2006

Feb. 6, 2006

I wrote a small program that compares files test1 and test2 to test3. If the files are different then it copies either test1 to test3 or the reverse. The problem is that the although the shutil.copy2 in thefunction change_files works without error it does not copy. Can anyone see what is wrong :- def compare_files(file_name1, file_name2): x = cmp (file_name1, file_name2) return x def open_files(file_name): file_is = open(file_name,'r') file_conts = file_is.read() return file_conts def change_files(file_1, file_2): yesorno = raw_input("Do you want them to be the same Y or N ") yesorno = string.upper(yesorno) if yesorno == 'Y': try: shutil.copy2(file_1, file_2) print "copy has been done " except: print "it did not work" #main file_name1 = open_files("test1.txt") file_name2 = open_files("test2.txt") file_name3 = open_files("test3.txt") import shutil import string x = compare_files(file_name3, file_name1) if x != 0: print "test1 and test3 are different" change_files("test1.txt", "text3.txt", file_name1) else: file_name1 = "test2.txt" print file_name1 x = compare_files(file_name3, file_name2) # print "x is " + str(x) if x != 0: print "test2 and test3 are different" change_files("test2.txt", "text3.txt") print "program finished" -------------------------------------------------------------------------------------------------------------------------------------- "Then you will know the truth, and the truth will set you free."

smtplib with yahoo smtp server
by Intercodes Feb. 2, 2006

Feb. 2, 2006

Hello everyone, I am working with a registration system for my website in mod_python. I needed to send mail to registered users for confirmation. Since I can't use my ISP's smtp server, I used yahoo's smtp server and my yahoo username and password to connect and send mail using this script (see below). But I get the following error. "Traceback (most recent call last): File "mail.py", line 12, in ? session = smtplib.SMTP(smtpserver) File "/usr/lib/python2.4/smtplib.py", line 255, in __init__ addr = socket.gethostbyname(socket.gethostname()) socket.gaierror: (-2, 'Name or service not known') " I got this script from some website I can't remember and just changed some values to get it to work. Is is possible to send mail like this? Is there any other easy way to do this? Thanks for your time. --------------------------- import smtplib smtpserver = 'smtp.mail.yahoo.com' AUTHREQUIRED = 1 smtpuser = 'intercodes@.[snip]..' ** smtppass = '[snip]' RECIPIENTS = ['intercodes@[snip]'] SENDER = 'intercodes@[snip]' mssg = "mod python" session = smtplib.SMTP(smtpserver)*if* AUTHREQUIRED: session.login(smtpuser, smtppass) smtpresult = session.sendmail(SENDER, RECIPIENTS, mssg)** -- Intercodes

Exit a child thread using threading.Thread() object
by Bernard Lebel Feb. 1, 2006

Feb. 1, 2006

A quick question. I have started a child thread using the threading.Thread class. Is there any way to cleanly exit the child thread? What I mean by "cleanly" is for example if you use the thread.start_new() function to create a child thread, the function running in the child thread can call thread.exit() to terminate the thread. I could not find anything comparable in the Thread object's documentation. Thanks Bernard

Newbie question re. Functions
by Jon Moore Feb. 1, 2006

Feb. 1, 2006

Hi, I am still working my way through my 'Python for absolute beginners book' and have hit a brick wall with one of the end of chapter exercises. The challenge says: Improve the function ask_number() so that the function can be called with a step value. Make the default value of step 1. The function looks like this: def ask_number(question, low, high): """Ask for a number within the range""" response = None while response not in range(low, high): response = int(raw_input(question)) return response The author has not eluded to 'step values' in anyway that I can see in the proceeding chapters! HELP! -- Best Regards Jon Moore

Re: [Tutor] Getting Running File's Name
by Hans Dushanthakumar Jan. 31, 2006

Jan. 31, 2006

Under WinXP, the variable sys.argv[0] holds the script file name (including the path). Not sure, but it may work the same under Linux as well. -----Original Message----- From: tutor-bounces(a)python.org [mailto:tutor-bounces@python.org] On Behalf Of Bryan Carbonnell Sent: Tuesday, 31 January 2006 3:11 p.m. To: tutor(a)python.org Subject: [Tutor] Getting Running File's Name Can Python return the name of the current file's name? In other works, if I am running a Python file (MyPythonFile.py) is there a function that will return 'MyPythonFile.py'? This will be used in Linux if that matters.

Life after beginner
by Pat Martin Jan. 31, 2006

Jan. 31, 2006

Hello, I have been reading about and playing with programming in python for awhile now. I have most of the basics down. I know what a tuple is, I know how to load modules, and I understand a fair amount of beginning programming theory. I have written some scripts for both home and work and have become fairly proficient at reading python code. My question is, what next? Is there some intermediate tutorials or books out there that I can start learning some real meat in the language? Things that just writing a simple script I might miss. I really want to learn about in depth programming and programming style but I am far from an expert. But with all the languages I have learned (really touched on) C, C++ perl, and python I seem to get to this point and then I am not sure where to go from here. I want to be able to write large projects in python and carry that experience over to the other languages as well. So any insight would be welcome. Thank you. Pat

ANN: Rur-ple 0.95 has been released
by Andre Roberge Jan. 30, 2006

Jan. 30, 2006

RUR-PLE 0.95 has been released. A link to the download page can be found at http://rur-ple.sourceforge.net (The site is slightly out of date, and there is no plan to update it in the future as it provides an excellent idea of what RUR-PLE is about.) This new version contains a few bug fixes and it should now work properly on MacOS. wxPython 2.6+ is strongly recommmended. There has been a few minor changes in the robot instructions, and the lessons has undergone some major changes. RUR-PLE stands for Roberge's Used Robot: a Python Learning Environment. This learning environment contains four main elements: 1. A simple html browser to look at the documentation and, potentially, the lessons. However, the new lessons use cascading style sheets which cannot be interpreted correctly by the browser. Usage of an external browser (Firefox :-) is strongly recommended. 2. A "robot world" with a robot that can accomplish tasks through Python programs. 3. A built-in interpreter which can be used to play with Python 4. A built-in file editor which can be used for futher Python explorations. The interface is available in English, French and Spanish. Translations are welcome! Version 0.95 contains 36 complete lessons (English version only). The lessons are also available as a separate download. Version 1.0, which will aim to be a "complete" Python tutorial for people that have never programmed before, should have approximately 50 lessons. A few "bonus" lessons have been included. In particular, it is suggested that you have a look at "A Robotic Fairy Tale". ===== In 1981, Richard Pattis introduced "Karel the Robot" as a tool to teach computer programming. Reeborg is a robot built on the 1981 Pattis' model... and it is starting to show its age. It has an oil leak, which allows us to follow its trail. Its compass is broken; it only knows if it is facing north or not, unlike Karel who could determine its orientation with respect to all four cardinal points. Pattis' Karel the Robot was named after the author Karel Capek, who popularized the word robot in his play Rossum's Universal Robots (RUR). While RUR-PLE shares the basic RUR acronym, in this case it stands for Roberge's Used Robot. However, through the magic of Guido van Rossum's Python, you can learn how to fix it and design a better one, worthy of the name Rossum's Universal Robot. ==== If you've read this far... Version 0.95 contains a new feature, which has been made available as a separate download: lightning.py This is a cross between a Python editor and a Python interpreter. Just enter a script in the Editor window, press "run", and you get the result in the output window. It handles input() and raw_input() through dialogs. I like it so much, that I submitted a simplified version to the online Python cookbook.
