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

Re: [Tutor] Module (.py file) that behaves like package

Hi Alan, > That depends on whether you can foresee a use for importlib in > your code. Slightly disagreeing here. I think reading importlib source is a great way of understanding how the python import system works (if you don't want to read C, that is). I think a learnt a lot and it helped me to understand some frustrating errors I encountered in my day to day programming, for example regarding module reloading (e.g. using autoreload in ipython). I was more wondering if the example I pointed out was really contrived or if this inconsistency in behavior could be an issue to fix. > "Did I really spend a week of my > life investigating importlib?" > To quote Ella Fitzgerald: "It's ain't what you do, it's the wat that you do it" ;) FWIW In 20 years of using Python I've never used > importlib in any of my real-world programs... > I'm sure somebody has, but not me.

Module (.py file) that behaves like package
by Quentin Agren Oct. 29, 2018

Oct. 29, 2018

Hi, By playing around with importlib I noticed that if you define `__path__ = [os.path.dirname(__file__)]` in a module named spam.py, then you could `import spam.spam.spam` or `from spam import spam`. In other words, spam.py behaves like a package although its loader, if asked, tells that it is not, and that accordingly you cannot `from . import spam` (in the same file, after setting `__path__`) Is this intended behavior? (Maybe I should just get out more...) Thanks! Quentin

Problem with task, please help!

Hello, I am an engineering student and we have to use Python. We don't have lessons so we all have to learn it on our own. We got a task and I am stuck on this: "Count the number of parcels for forrest ground and count the number of parcels for orchard ground". I think I have to use the for-loop but I don't know how. This is what i already have: import numpy as np import csv from matplotlib import pyplot as plt def getlanduse(): with open('LandUse.csv', encoding='latin-1') as csvfile: readCSV = csv.DictReader(csvfile, delimiter=';') return list(readCSV) In the file i renamed the things we need from dutch to english :) Thank you very much!

I have the following gathering dust on my shelf: The Python Standard Library by Example by Doug Hellmann 3rd printing May 2012 Dive Into Python by Mark Pilgrim 2004 Learn Python the Hard Way (2nd Edition) by Zed A. Shaw June 2011 If anyone wants any or all of them, I'm happy to send them on for what ever it costs to mail. I could mail from either the US (94924 area code) or from Canada (V9L 6T2)- which ever works out cheapest (which may depend on the destination although in general I believe costs are cheaper in the States.) -- Alex Kleider (sent from my current gizmo)

Python 3.6 update?
by Jim Oct. 27, 2018

Oct. 27, 2018

Mint 18.1 Default python3 = 3.5 Python 3.6 installed for use by a virtual environment. Update manager just informed me of an update for python 3.6 to 3.6.7-1. When I started to install it, I got a dialog saying: this upgrade will trigger additional changes. The following 2 packages will be removed python3-dev & python3-venv. I am wondering what will happen to the virtual environment I have installed that uses python 3.6. Will the 2 packages be replaced and the virtual environment continue to work or is there some other steps I will need to take. Regards, Jim

Hi there I need to draw a patten with turtle in python 3.7 but I cant get it to work here are the specs of the pattern and my code so far can you please help • Specifications of the pattern o The radius of the three heads is 10. o The length of legs is 30. o The length of the sizes of the two triangles (the body of runner-up and third-place) is 40. They are all equal-size triangles. The winner’s body is a 40x40 square. o The width of the three blocks of the podium is 60. The heights are 90, 60, and 40 respectively.

Hi All , I found a logic : 1.initialize print flag to false 2. Save starting and ending times in variables 3. loop to read or process sequential lines in the file a. See if line contains time b. If it does, extract time c. Compare time in line to starting time d. If line time is greater than or equal to start time, set print flag to true e. If line time is greater than ending time, set print flag to false f. If print flag is true print line g. End of loop — process next line start_time = 2018-10-22 10:21:15 end_time = 2018-10-22 10:21:25 f4 = open ( r"logC11.txt", 'r' ) for line in f4.readlines(): a = re.findall( r'\d\d/\d\d/\d\d\s[012][0-9]:[0-5][0-9]:[0-5][0-9]', line ) print a #b = a.group(0) newtime = datetime.datetime.strptime ( a[0], '%m/%d/%y %H:%M:%S' ) print newtime if newtime > y and newtime < k: flag = True else: flag = False if flag : print line else : continue But it errors out : C:\Python27\python.exe D:/QI/test_qopatch.py Traceback (most recent call last): 2018-10-22 10:21:15 File "D:/QI/test_qopatch.py", line 32, in <module> 2018-10-22 10:21:25 newtime = datetime.datetime.strptime ( a[0], '%m/%d/%y %H:%M:%S' ) ['04/26/18 06:11:52'] 2018-04-26 06:11:52 [] IndexError: list index out of range Process finished with exit code 1 Please provide the code Thanks, On Sat, Oct 27, 2018 at 1:35 PM <tutor-request(a)python.org> wrote: > Send Tutor mailing list submissions to > tutor(a)python.org > > To subscribe or unsubscribe via the World Wide Web, visit > https://mail.python.org/mailman/listinfo/tutor > or, via email, send a message with subject or body 'help' to > tutor-request(a)python.org > > You can reach the person managing the list at > tutor-owner(a)python.org > > When replying, please edit your Subject line so it is more specific > than "Re: Contents of Tutor digest..." > Today's Topics: > > 1.

I need to change the code according to my requirement . My requirement is to start(y) and end timestamp (k) from logA.txt which the code is getting now correctly then open logC11.txt see the timestamp nearest to start(y) which its doing now 2018-10-22 10:21:23 and then look for errors(ERR-2 and ERR-3) in the lines in logC11.txt starting from 2018-10-22 10:21:23 and before the timestamp (k) ==> here i need help my code is searching for ERR-2 and ERR-3 occurance in logC11.txt anywhere in the file I want it to search in a specific window of 2018-10-22 10:21:23 and less than timestamp (k) so the my present coded has printed the output : *Install patch1 - wrong solution This it will print if it executes the following block : if re.search ( "ERR-2", newst ): a = re.findall ( "\d\d/\d\d/\d\d\s[012][0-9]:[0-5][0-9]:[0-5][0-9]", newst ) for i in range ( len ( a ) ): newtime = datetime.datetime.strptime ( a[i], '%m/%d/%y %H:%M:%S' ) if newtime > y and newtime < k: print "Install patch1 Now if you see ERR -2 in logC11.txt it occured at 26th april instead it should have ignored it because the time windows received from logA.txt y (2018-10-22 10:21:15) and k (2018-10-22 10:21:25) : LOG file opened at 04/26/18 06:11:52 ERR-2: OS message: No child processes operation "wait", location "skudmi:prp:6" In short I would like to only search in lines : LOG file opened at 10/22/18 10:21:23 ERR-3: patchObjectPossible causes are:" Trim whitespace same as SQL Loader How do I acheive this ?
