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

Regular User defined functions Vs Generator functions
by Manprit Singh Nov. 1, 2020

Nov. 1, 2020

Dear sir , I have a question , why not to prefer generator functions instead of regular user defined functions, where i have problem like as that given below : I have to write a function that can return index of each and every occurrence of substring w in string st1, st1 & w given below: st1 = "I am a boy, i am an engineer, i am a genius" w = "am" If i have to write a function to solve this problem, i feel generator function is more good( as compared to regular user defined function), that i have written below : def ind_word(st, w): n = 0 while True: n = st.find(w, n) if n != -1: yield n else: break n += 1 st1 = "I am a boy, i am an engineer, i am a genius" w = "am" print(*ind_word(st1, w)) will give result 2 14 32 Need your suggestions. Regards Manprit Singh

Please tell me some suggestions for this problem, I have tried this code but it is not giving me the correct output..... *Problem*: Use Python to calculate how many different passwords can be formed with 6 lower case English letters. For a 1 letter password, there would be 26 possibilities. For a 2 letter password, each letter is independent of the other, so there would be 26 times 26 possibilities. Using this information, print the amount of possible passwords that can be formed with 6 letters. pass_proability = 1 for i in range(1,7): pass_proability = pass_proability * i * 26 # print(pass_proability) print(pass_proability) *Please consider the environment before printing this e-mail.

by Manprit Singh Oct. 31, 2020

Oct. 31, 2020

Dear sir , Consider a string st1 = "I am a boy, i am an engineer, i am a genius" i have to find the index of every occurrence word "am" in the string st1. i have written a program below: st1 = "I am a boy, i am an engineer, i am a genius" w ="am" for i in range(len(st1)): if st1.find(w, i, i + len(w)) != -1: print(i) need to know, if this problem can be done in a more clean way ? Kindly give some hints so that i can rewrite it in a more clean and clear way . Regards Manprit Singh

Confusion about definition of proper subset in python set
by Manprit Singh Oct. 30, 2020

Oct. 30, 2020

Dear sir , Consider explanation given about set < other in python official documentation Test whether the set is a proper subset of *other*, that is, set <= other and set != other. This confuses me actually. set <= other and set != other , how it is possible at same time ? As far as i know, if S is a set and ss is its proper subset, then ss is strictly contained in S and necessarily excludes at least one member of S. Need some light on it. Regards Manprit Singh

Pip Issue
by Elliot Lee Oct. 28, 2020

Oct. 28, 2020

I think this is probably just a beginner’s issue and should be able to be fixed quickly, I’m just not sure how to do it. I was watching a tutorial about hosting a Discord Python bot on Heroku, but I’ve hit a problem where I can’t use the command “pip install pipreqs”. This error results: I searched online for answers and it asked me to look for Python on the C local disk, but I cannot find it in there. I know I have Python installed, so I assumed I had to move my folder (with material for the bot) into that folder in order to access pip commands. What am I doing wrong? Thanks.

Hello, I have been using python for a while and I have a question for my code. How do I write a program that returns a multiplication table of a number up to 12. For example multiplication_table(6) would return "6 12 18 24 30 36 42 48 54 60 66 72 "

Re-Project Vector Datasets
by Steven Douglas Oct. 28, 2020

Oct. 28, 2020

I am writing a script that re-projects vector datasets in a folder. From this, it will then create a script tool. The final script tool will have only two textboxes for input. The first will be to input the target data folder and the second calls for a shape file or featureclass that calls for the target projection dataset. In short, it will re-project the shapefile vector datasets in the folder to match the target dataset's projection. ***************** The script will not contain any hard-coded values such as dataset, path, or projection names. Here's what I've got so far (error mentioned afterwards below): import arcpy #set up the paths targetFC = "C:\\GISData\\CountyLines.shp" folderEnvironment = "C:\\GISData" #get spatial reference for the target feature class targetDescribe = arcpy.Describe(targetFC) targetSR = targetDescribe.SpatialReference targetSRName = targetSR.Name # Get a list of my feature classes arcpy.env.workspace = folderEnvironment listOfFCs = arcpy.ListFeatureClasses() #Loop through the list of FCs for currentFC in listOfFCs: #Read the spatial reference of the current one currentFCDescribe = arcpy.Describe(currentFC) currentFCSR = currentFCDescribe.SpatialReference currentFCSRName = currentFCSR.Name if currentFCSRName != targetSRName: print ("Spatial references don't match") else: print ("Spatial references do match") if currentFCSRName == targetSRName: else: # Determine the new output feature class path and name outCS = currentFC[:-4] +"_projected.shp" arcpy.Project_management(currentFC, outCS, targetSR) rootName = currentFC[:-4] print (rootName) print (rootName +"_projected.shp") ***************** Error: IndentationError: expected an Indented block -- on line 36 (the last "else:" It's not working. Please help!
