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

Questions about the deprecation of standard library modules
by boB Stepp April 2, 2019

April 2, 2019

While reading in chapter 3 of "Learning Python, 5th ed." by Mark Lutz, I was playing around with reload() in the imp module. In the interpreter I did a "from imp import reload" and then help(reload). This had a warning that it was deprecated. After a search online I found that the entire imp library was deprecated since Python 3.4. The aforementioned book covers through Python 3.3. This got me to wondering when the imp module would be removed from Python 3, which led me to finding PEP 4. In it it says: Module name: imp Rationale: Replaced by the importlib module. Date: 2013-02-10 Documentation: Deprecated as of Python 3.4. There is no mention as to _when_ the module might be removed. PEP 4 says that a deprecated module may be removed as early as the next Python release after it becomes deprecated. Also the PEP states that if a module exists in both Python 2.7 and Python 3.5, it will not be removed until Python 2.7 is no longer supported, which, I suppose, means next year. So my main question is how does one know in which Python version a deprecated module will be removed? I'm not too concerned about the imp module, but _do_ want to know how the removal process works for deprecated standard library modules that I might be interested in. -- boB

Python Django Query

Hi Everyone, I need some guidance / corrections to my code. I hosted a demo site on pythonanywhere.com and to test the initial pages I wrote some test code. Good news, put in 10 hrs, tried so many suggestion given on the net, yet non worked. So finally mailing the list. Objective : display main page with multiple links to other pages. Use jQuery plugins, click the link on main page and open other pages. The following path and pages are posted below. Thanks Nitin Chandra ------------------------------------------------------------ ERROR When I click on 'Table' link on 'home' page, the following error is displayed http://selftech.pythonanywhere.com/table.html Page not found (404) Request Method:GET Request URL:http://selftech.pythonanywhere.com/table.html Using the URLconf defined in eduinfra.urls, Django tried these URL patterns, in this order: admin/ [name='home.html'] The current path, table.html, didn't match any of these. You're seeing this error because you have DEBUG = True in your Django settings file.

operate on files based on comparing filenames to today's date
by Matthew Herzog March 28, 2019

March 28, 2019

I have cobbled together this code which gives me regex matches of files whose names either begin with either YYYYMMDD_? or erased_YYMMDD_? and whose extensions are exml or ewav. Now I need to compare the date string (regex match) in the filename to today's date. If the result of the comparison results in YYYMMDD being older than 180 days, I should print something to indicate this. If not, nothing need be done. Should I write another function to compare each matched regex to today's date or is that overkill? Thanks. todaystring = date.today().strftime("%Y%m%d") oldest = date.today() - timedelta(days=180) def get_files(extensions): all_files = [] for ext in extensions: all_files.extend(Path('/Users/msh/Python/calls').glob(ext)) return all_files for file in get_files(('*.ewav', '*.exml')): print(re.match("[0-9]{8}|erased_",file.name)) -- The plural of anecdote is not "data."

Hello, I'm having issues running python and sublime on my computer. Every time I try to run either one I get an error message that looks something like this: "Traceback (most recent call last): File "<pyshell#0>", line 1, in <module> python NameError: name 'python' is not defined I think I need to edit my path but I'm not sure how to do that correctly so any help would be greatly appreciated.

(no subject)
by Matthew Herzog March 26, 2019

March 26, 2019

I have a Python3 script that reads the first eight characters of every filename in a directory in order to determine whether the file was created before or after 180 days ago based on each file's name. The file names all begin with YYYYMMDD or erased_YYYYMMDD_etc.xls. I can collect all these filenames already. I need to tell my script to ignore any filename that does not conform to the standard eight leading numerical characters, example: 20180922 or erased_20171207_1oIkZf.so. Here is my code. if name.startswith('scrubbed_'): fileDate = datetime.strptime(name[9:17], DATEFMT).date() else: fileDate = datetime.strptime(name[0:8], DATEFMT).date() I need logic to prevent the script from 'choking' on files that don't fit these patterns. The script needs to carry on with its work and forget about non-conformant filenames. Do I need to add code that causes an exception or just add an elif block? Thanks. -- The plural of anecdote is not "data."

Re: [Tutor] How to store scores of a race's players

A good mailing list to use instead of the main python list is tutor(a)python.org. I'm including that list in the reply addresses; please use that address in the future and always reply all so a copy goes to that list. This looks like a homework assignment. Be advised we won't write code for you but we will help you when you get stuck and provide some guidance. I'm personally curious as to who wrote that specification, since it is not well written. One of the questions that fails to address is what if two or more players have the same high score? It's also a little hard to guide you since we don't know what you've already learned. One of the fundamental concepts in computer programming is that of a loop. Since the requirements indicate there will be more than one race that requires a loop. The simplest python construction for a loop is a while. Within that Loop you write the code once rather than rewriting it as you have done. I hope that is enough to get you started. Please apply that advice as best you can and come back with a revised program. > p1 = int (input ("Insert score of the first player: ")) > p2 = int (input ("Insert score of the second player: ")) > p3 = int (input ("Insert score of the third player: ")) > > race = str (input ("Is the competition finished?")) > > totalp1 = 0 > totalp2 = 0 > totalp3 = 0 > > winner = 0 > > if p1 > p2 and p1 > p3: > winner = c1 > elif p2 > p1 and p2 > p3: > winner = p2 > else: > winner = p3 > > if "yes" in race: > print("The winner is:",winner) > else: > p1 = int (input ("Insert score of the first player: ")) > p2 = int (input ("Insert score of the second player: ")) > p3 = int (input ("Insert score of the third player: ")) > > race = str (input ("Is the competition finished?")) > > You read above just my toughts, is there someone who could help me to understand how to solve it? > > Regards. > ^Bart > -- > https://mail.python.org/mailman/listinfo/python-list
