Scripting Calligra sheets with Python
by Jim Byrnes Jan. 31, 2022

Jan. 31, 2022

I am trying to script Calligra Sheets (formerly KSpread) with python. I have gotten some of the included example scripts to run so I know python scripting is running. I found the following snippet on their website: import KSpread sheet = KSpread.view().sheet() # swap text of B5 and C6 t1 = sheet.text("B5") t2 = sheet.text(6,3) sheet.setText("B5", t2) sheet.setText(6, 3, t1) # swap value of D7 and E8 v1 = sheet.value("D7") v2 = sheet.value(8,5) sheet.setValue("D7", v2) sheet.setValue(8, 5, v1) Error: 'str' object has no attribute 'text' File "file:///usr/share/kde4/apps/sheets/scripts/extensions/myswap.py", line 4, in <module> This error message appeared in a dialog box. I've taught myself some Python but I don't understand what is happening here. Shouldn't t1 be a sheet object? What would cause it to be a str instead? Thanks, Jim

Desktop Notifications on Linux
by Dharmit Shah June 29, 2017

June 29, 2017

Hi all, I am trying to create a script that will go through the /var/log/secure file on a Linux system and provide desktop notifications for failed login attempts. Here is the code - http://pastebin.com/MXP8Yd91 And here's notification.py - http://pastebin.com/BhsSTP6H I am facing issue in the function "new_attempts_from_last". I am not able to raise a desktop notification from this function. It always fails with this traceback - http://pastebin.com/cgHMScv3 I see this error only when I try to raise a notification from the aforementioned function. If I run test examples under /usr/share/doc/notify-python/examples, it works just fine. Also, if I try to raise a notification from under if __name__ == "__main__":, it works without any issues. So I don't think there's any issue with OS's notification daemon. Running from python shell like below also works fine: In [1]: import notification In [2]: notification.notification("Hey") What am I missing or doing wrong here? If it matters, I am running Fedora 20, python 2.7 and Cinnamon desktop environment. For readability purposes, I have provided pastebin links. Let me know if this is not the correct way. Regards, Dharmit.

by fabu desay March 8, 2016

March 8, 2016

If I got the problem correctly,you can equally create + open a file file = open(filename,+wr) The file should have the HTML extension You can now pace your web contents in the file.html you created that should work by trigering the python file you programed in and it inturn creates the website or pages of your choice an example like this could help webpage = open('index.html', 'w+') webpage.write("<html><head><title>My web page</title></head>"); webpage.write("<body>This the body</body></html>"); webpage.close()

HELP I need help with Python Setup or to reach Marilyn Davis
by carolynn fryer July 11, 2015

July 11, 2015

I am at the point where I am just spinning my wheels. I tried to get help with logging on but so far I am just getting frustrated. I have a problem that I brought up the first night in class but couldn't seem to get help then. Sorry if I am at the point where I am totally frustrated and I need HELP. PLEASE. I did not turn in homework because of the fact that I can not run anything without getting a syntax error. I tried setting up a path for python environment variables and a few other things but I am getting no where. Can you give me some suggestions why I can't run anything. I have windows 7 on my home computer, and windows 8 on my laptop and they are both doing the same thing. So it has to be something I am doing or not doing. I really do not like being behind/late in anything so that is making me even more frustrated. I suppose I am even more frustrated and afraid to ask because I kink of got a slap in the face last time I took a course here and the instructor would not help. But that was a way different situation, I simply could not understand his English and then he told me he did not have any patience. Excuse me but I just about died when he, an INSTRUCTOR told me that. I worked at Stanford for 25 years and to hear an instructor say those words was unthinkable. Anyway you can maybe understand my reluctance to ask for help but I need help. Any suggestions?? When I use one of the computers at school everything works just fine. Except I can not get my own computer to log on when I am there. So again that is why I said it is my system and something in my set up that I don't have. Sorry for the long note, I was just letting out a little frustration. LOL Thx for any suggestions, Carolynn Fryer ps: I know this is not the proper way to get ahold of you but I could not find nor have time to find any other way. The UCSC system is not very user friendly

Wave module

Hello, I'm trying to join two .wav files with the wave module. But when I try to use wave.open(filename, "rb") I receive the following error: Traceback (most recent call last): File "<stdin>", line 1, in <module> File "F:\PortablePython1.0\lib\wave.py", line 483, in open return Wave_read(f) File "F:\PortablePython1.0\lib\wave.py", line 162, in __init__ self.initfp(f) File "F:\PortablePython1.0\lib\wave.py", line 143, in initfp self._read_fmt_chunk(chunk) File "F:\PortablePython1.0\lib\wave.py", line 264, in _read_fmt_chunk raise Error, 'unknown format: %r' % (wFormatTag,) wave.Error: unknown format: 85 I read somewhere that there are various wave formats, only some supported by Python. Is this true? If so, is there any way I can convert my wave files into a supported kind? Thanks!

Umm.. I need help on changing Global Variables.
by Tallen Grey Smith Jan. 31, 2015

Jan. 31, 2015

So, I’m trying to make a very simple game that involves time management properly, but I’m having an issue. level = 1 player_health = 100 enemy_health = 100 steps = 10 civilians = 20 charge = 0 name_2 = 'Bob' def game(): global level global player_health global enemy_health global steps global civilians global charge print "\n" * 80 print "Level " + str(level) print name_2 +": " + str(player_health) +" HP" print "Centurion: " + str(enemy_health) + " HP" print "Distance: " + str(steps) + " feet" print "Weapon Charge: " + str(charge) print "Civilians Remaining: " + str(civilians) print "A Centurion lands near the gate! Prepare the Laser!" action_1 = raw_input("Do you want to charge the laser or fire?") action_2 = action_1.lower() if action_2 == "charge": charge == charge+10 steps == steps-1 civilians == civilians -1 charge_1() def charge_1(): level player_health enemy_health steps civilians charge print "\n" * 80 print "Level " + str(level) print name_2 +": " + str(player_health) +" HP" print "Centurion: " + str(enemy_health) + " HP" print "Distance: " + str(steps) + " feet" print "Weapon Charge: " + str(charge) print "Civilians Remaining: " + str(civilians) print "The Centurion moves closer! Hurry!" action_1 = raw_input("Do you want to charge the laser or fire?") action_2 = action_1.lower() if action_2 == "charge": charge = charge+10 steps = steps-1 civilians = civilians -1 charge_1() game() thats my code, and I want it to where if I type charge it’ll make my charge go up 10, my steps go down 1, my divs going down 1, and it to go to my charge_1 function, which should do the same thing but with a tweaked dialog box. But no matter how hard i try, once it gets to the charge_1, it always says that the variables that I changed where referenced in previous functions and it can’t pull them. How can I change this to get a variable that when changed in my If statement, would be useable in other functions? Thanks.

Jan. 31, 2015

While managing the moderation queue I saw a message about using Python for serial comms using a RaspberryPi. It came from a C/C++ programmer wanting to use python. I think I accidentally hit reject instead of accept. If you recognise what I'm talking about please resend your post.
