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.

I think we need more information on what a "virtual environment folder" is. I do not know what that term means.

Hello, I found this simple script online but when I execute it I get the following error: "TypeError: 'list' object is not callable" Here is the code sample:import subprocess ls_output= subprocess.check_output(['dir']) I searched online and found a another similar code sample (http://www.opentechguides.com/how-to/article/python/57/python-ping-subnet.h…) but when I run it on my system I get the same error.Any feedback is very much appreciated. Thank you.

In entering five random number, how can I best sort it into ascending order, such as 0511414453? Using Linux 2.7.6 in Ubuntu 14.04.4. Thanks. number01 = "41" number02 = "11" number03 = "05" number04 = "53" number05 = "44" line = number01 + number02 + number03 + number04 + number05 print print line line.sort() print print line 4111055344 Traceback (most recent call last): File "Mega_Millions_01_Tickets_Entry_TEST_TEST.py", line 11, in <module> print line.sort() AttributeError: 'str' object has no attribute 'sort'

Issue with Code
by Olaoluwa Thomas April 30, 2016

April 30, 2016

Hi, I'm new to Python and programming in general. I came across a simple exercise that is used to compute gross pay when prompted to enter number of hours and hourly rate. I've attached the scripts in question (created via Notepad++). The 1st script I wrote worked perfectly. The 2nd script makes amendments to the 1st by increasing the hourly rate by 50% when number of hours is greater than 40. The problem with this script is that the "else" statement (which is equivalent to the 1st script) does not compute gross pay accurately as seen in the attached screenshot. I would appreciate a logical explanation for why the "else" statement in the 2nd script isn't working properly. I'm running Python v2.7.8 on a Windows 7 Ultimate VM via Command prompt and my scripts are created and edited via Notepad++ v6.7.3 *Warm regards,* *Olaoluwa O. Thomas,* *+2347068392705*

Re: [Tutor] Is there a library which has this object?
by Yeh April 30, 2016

April 30, 2016

> You need to post in plain text otherwise the mail system mangles your > code, as you can see. I'm sorry for it. :( my code is: import time import numpy as np start = input("please input the value of start: ") end = input("please input the value of end: ") dur = input("please input the value of dur: ") array = np.linspace(float(start),float(end),1000) dur = float(dur)/len(array) for i in array: print(float(i)) time.sleep(dur) and it worked, then, I was trying to make it as a function: def myFunction(start,end,dur): ........... for i in array: return i time.sleep(dur) there is no errors. because it just post the first number in the array, even I change the order of time.sleep() and return. I have checked the cycle(), and yes, that is what I'm searching! But, I got an other question, how to stop cycle() by manual? such as press "q", then break the cycle(). and has same question to make it be a function. Thanks Yeh Z

pytsk
by Tees, Peter (EthosEnergy) April 29, 2016

April 29, 2016

Hi folks I'm pretty new to Python and programming, I've done the first four modules of the Python course at Coursera.org to get started Now I want to put what I've learned to good use, based on the articles by David Cowen at the Hacking Exposed blog and in particular his series "Automating DFIR - How to series on programming libtsk with Python" (which is Python 2.7, same as Coursera.org) The very first thing to be done, after installing Python, is to grab a Windows installer for the pytsk library from here https://github.com/log2timeline/l2tbinaries/blob/master/win32/pytsk3-4.1.3-… But that link doesn't work (Page 404), and any other downloads I've seen so far refer either to binding to The Sleuthkit or refer to pytsk3 which I don't think is what I need Can anyone point me to a Windows 32-bit installer for a pytsk library that will work with Python 2.7?

Extracting bits from an array
by Colin Ross April 29, 2016

April 29, 2016

Hello, I have an array that takes on the following form: x = [1000,1001,1011,1111] The array elements are meant to be binary representation of integers. Goal: Access array elements and extract the first two bits. e.g. Final result would look something like this: x_new = [10,10,10,11] What I have tried: data_indices = range(4) # Set up array of values to loop over for idx in data_indices: f = x[idx] # Index into array of x values f_idx = f[:2] # Extract first two elements print f_idx I then receive the following error: IndexError: invalid index to scalar variable. Any help with accomplishing my outline dgoal would be greatly appreciated. Thank you. Colin
