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

guess my number game (reversed)
by chiara pascucci Oct. 6, 2018

Oct. 6, 2018

Hello. I am very new to learning Python, and I would need some help with a little game I am trying to write. I am trying to write a game where the user is asked to think of a number from 1 to a 100, and the computer tries to guess it. Now, after every guess I would want the programme to ask whether its guess is right, too low, or too high, and then take another guess based on the user's input. The programme works fine if the it guesses the number right on its first try, but when the users inputs "too low" or "too high" an infinite loop is returned. I thinkI have done something wrong in my while loop and that my sentry variable is somehow wrong -but I can't seem to be able to fix it! Any help or commments would be very appreciated. Below is the code written so far Many thanks Chiara print("think of a number from 1 to 100") print("I will try and guess it!") import random number = random.randint(1,100) print(number) answer = input("is this right, too high, or too low?") while answer != "right": if answer == "too high": number2 = random.randint(1,number) print(number2) elif answer == "too low": number3 = random.randint(number,100) print(number3) print("I finally guessed your number. Thank you for playing") input("\n\nPress enter key to exit")

Hello, I'm new to Python and I've been having a frustrating time with python because I'm trying to import tkinter and it's saying that tkinter is not defined, that it doesn't exist and now i'm not able to run some of my programs since it states that there is no module named tkinter. If you could help that would be great! Sincerely, Jorge Herrera jorgherrera96(a)gmail.com

Best solution to modifying code within a distributed library
by Chip Wachob Sept. 29, 2018

Sept. 29, 2018

Hello once again, I'm sure this is probably way outside my 'pay grade' but I would like to try an experiment and I'm not sure how to go about it. I'm using the Adafruit FT232 libraries found here: https://github.com/adafruit/Adafruit_Python_GPIO/blob/master/Adafruit_GPIO/… I'm experiencing some wiggling of the IO lines when I configure the IO pin direction. I've looked through the code in the FT232H.py file and found what I believe to be the culprit. I would like to comment out line 340 (self.mpsse_write_gpio()) to prove that this is what is causing glitches that I do not want. Using the .__file__ inside the interpreter I learned that the file is located here on my machine: /usr/local/lib/python2.7/dist-packages/Adafruit_GPIO-1.0.3-py2.7.egg/Adafruit_GPIO/FT232H.pyc But obviously, this is a binary file. If I understand enough about Python, I believe that I need to edit the FT232H.py file in the .egg file to implement the change. There is also likely some sort of compilation that needs to be done once the change is made... BUT As I've also learned from our friend Google, one should not be editing .egg files, etc. So, can the experts out there point me to the proper method of implementing the change? IF, this ends up resolving my issues, then I presume that I will need to create my own .egg file. Is this accurate? As always thank you in advance for your time,

Python programming help!
by V E G E T A L Sept. 23, 2018

Sept. 23, 2018

Hello folks! So, I'm pretty much a noob still experimenting with basic commands. I wanted to make a code that checks if the value of one variable is less, equal or greater than the other. Pretty simple right? But then, this problem emerged. I would really love some help, since I'm stuck and can't figure out what I've done wrong. PS: I'm using Anaconda and JupyterNotebook.

Fwd: How to roughly associate the values of two numpy arrays, or python lists if necessary
by Alan Gauld Sept. 23, 2018

Sept. 23, 2018

Forwarded to list.... ---------------------------- I have, I suspect, an elementary problem that I am too inexperienced to resolve. I have two numpy arrays, each representing the values of a specific property of a set of cells. Now, I want to associate the two values for each cell, that is for each index of the numpy array. But I want to associate them ROUGHLY, that means, APPROXIMATELY, so that there is a weak, linear correlation between the values representing one property and the values representing the second property of each individual cell. Up to now I have used the following procedure. I have divided each population of values into four segments based on the value of the standard deviation thus. 1. values > mean + 1 std (sigma) 2. values > mean but < mean + 1 std (sigma) 3. values < mean but > mean + 1 std (sigma) 4. values < mean + 1 std (sigma). Then I randomly select a value from group 1 for the first property and I associate it with a randomly selected sample of the second property from its group 1. And so on through the total population. This gave me a very rough linear association between the two properties, but I am wondering whether I can do it in a simpler and better way. -- Sydney _________ Professor Sydney Shall Department of Haematology/Oncology Phone: +(0)2078489200 E-Mail: sydney.shall [Correspondents outside the College should add @kcl.ac.uk]

Help understanding base64 decoding
by Ryan Smith Sept. 13, 2018

Sept. 13, 2018

Hello All, I am currently working on a small utility that finds any base64 encoded strings in files and decodes them. I am having issue understanding how the Base64 module actually works. The regular expression that I am using correctly matches on the encoded strings. I simply want to be able to convert the match of the encoded ascii string to it's decoded ascii equivalent. For example the base64 encoded ascii string 'UwB5AHMAdABlAG0ALgBkAGwAbAA=' will decode to 'System.dll' if I use an online base64 decoder. However I get a completely different output when trying to codify this using python 3.6.5: >>>import base64 >>>import binascii >>>test_str = 'UwB5AHMAdABlAG0ALgBkAGwAbAA=' >>> base64.b64decode(test_str) b'S\x00y\x00s\x00t\x00e\x00m\x00.\x00d\x00l\x00l\x00' >>>temp = base64.b64decode(test_str) >>>binascii.b2a_base64(temp) b'UwB5AHMAdABlAG0ALgBkAGwAbAA=\n' I understand that when decoding and encoding you have to use bytes objects but what I don't understand is why I can't get the proper conversion of the original ascii string. Can someone please point me in the right direction? Thank you, Ryan

IDLE
by Roger Lea Scherer Sept. 11, 2018

Sept. 11, 2018

Can you direct me to where or how to update from Python 3.6.5 Shell, I think it is also called IDLE 3.6.5, to Python 3.7 Shell? I looked at the documentation which seems like there is another one, slightly improved. I've downloaded Python 3.7, but can't figure out how to upgrade the IDLE/Shell. And I can't for the life of me remember how I originally got the Python 3.6.5 Shell. Thank you -- Roger Lea Scherer 623.255.7719 *Strengths:* Input, Strategic, Responsibility, Learner, Ideation
