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.

March 9, 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()

Hello, This below given code is giving a race condition, i.e. sometimes gives the result as expected, sometimes gives error, sometimes just does nothing. It is part of a subclassed qt form which i am using as main dialog. This behaviour occurs when i close the dialog whereby ending the application. what i want to achieve is that when the dialog is closed if any unsaved data, prompt the user.

Missing Standard Libraries on Python 3.5 for Mac
by Andrew Machen Feb. 29, 2016

Feb. 29, 2016

Hi, I am new to Python, and I am trying to use a Python Standard Library, namely ‘unicodedata’, however it appears to be missing (others are also missing) from the built-in libraries that come with Python 3.5 for Mac. I have searched the following directory, but have not found the library: /Library/Frameworks/Python.framework/Versions/3.5/lib/python3.5 I have tried reinstalling Python 3.5 and also tried Python 3.4.3, and neither install the ‘unicodedata’ library. Is there anyway to install it manually? The library is present in the Python 2.7 version provided by Apple, however I was hoping to learn and use Python 3. The library is present in the Linux version of Python 3.5 that I have tried. Your help is greatly appreciated. -Andrew

Py/selenium bindings
by bruce Feb. 29, 2016

Feb. 29, 2016

Hi. This might be a bit beyond the group, but I figured no harm/no foul. I'm looking to access a site that's generated via javascript. The jscript of the site is invoked via the browser, generating the displayed content. I'm testing using py/selenium bindings as docs indicate that the py/selenium/PhantomJS browser (headless) combination should invoke the jscript, and result in the required content. However, I can't seem to generte anything other than the initial encrypted page/content. Any thoughts/comments would be useful. The test script is: #!/usr/bin/python #------------------------------------------------------------- # # FileName: # udel_sel.py # # #------------------------------------------------------------- #test python script import subprocess import re import libxml2dom import urllib import urllib2 import sys, string import time import os import os.path from hashlib import sha1 from libxml2dom import Node from libxml2dom import NodeList import hashlib import pycurl import StringIO import uuid import simplejson import copy from selenium import webdriver #---------------------------------------- if __name__ == "__main__": # main app url=" http://udel.bncollege.com/webapp/wcs/stores/servlet/TBListView?storeId=3755… " driver = webdriver.PhantomJS() driver.get(url) xx=driver.page_source print xx sys.exit() ---------------------------------------------------------------------------

Convert structured 1D array to 2D array
by Ek Esawi Feb. 28, 2016

Feb. 28, 2016

Hi All— I used genfromtxt to read a file with multiple data types. The result was a 1D array of tuples; for example [(1, 2, 3), (‘a’, b’, ’c’), (‘12/12/2009’, ’2/4/2014’, ‘3/4/200)’] I am trying to convert this structured array to a 2D array. Is this possible where the data types in the 1D array are preserved? Thanks in advance-EKE

by CMG Thrissur Feb. 28, 2016

Feb. 28, 2016

Hello, I just wanted an opinion on the subject, asyncio and threading both seam to do the same job, but i feel threading is better because of the multiple ways i can control it. Just want get the groups opinion based on there experience in using asyncio or threading in real life problems. thanks George
