Possible thonny 4.1.4 error

[MikeGreen99]

I have encountered an error in how the thonny ide executes my program. The program reacts differently in the thonny environment if I remove a 'print' statement.

However, If I run the program in ubuntu 22.04 Terminal, it will always execute correctly.

I would like to attach the program and a text file to simulate the error, but I do not know how to do so.

Is there a way to contact thonny.org via email ?

Thanks,
MG...

Try to create a minimal program that demonstrates the error and post it here.

Hi. Thanks for your prompt response. I have attached a simple program and a small test file. The program will run fine, reading every record to eof. However, if I remove the "print (Data[1:6])" on line 18, the program does not read to eof. Note: In case you are having trouble reading the attached ascii file CARSCODE.FIL, I have made a copy of it to CARSCODE.txt. (I am using python 3.10.12 on ubuntu 22.04). If you require any more info, please do not hesitate to ask. Thanks, M.... Sent with [Proton Mail](https://proton.me/) secure email.

I don't think anyone here has time for debugging this program.

If you think Thonny is faulty, you need to construct a much simpler program for demonstrating this.

Hi. Thanks for your prompt response. I'm not asking you to debug the program - it works just fine. However, it reacts differently when I comment out a print statement. In ubuntu Terminal, the program runs identical, with or without the print statement. The program is below - just 8 lines of code. I did attach the file that is being read. You will have to change the file path in the program. # ErrorThonny.py MG Feb.06.2024 # ubuntu 22.04 Thonny 4.1.4 python 3.10.12 # This program works fine - it read all records to eof. # HOWEVER, IF I REMOVE the "print (Data[1:6])" on line 18, # THAN EOF IS NOT REACHED print ("Begin") SubCodeFile= "/media/mg/DProgs/CarSystem/CARSCODE.FIL" f = open(SubCodeFile, "rt") while (Data := f.readline()): #Read to EOF print(Data) print (Data[1:6]) # TRY REMOVING THIS STATEMENT print ("eof") f.close() M....

In your second message I don't see any program. In your third message, there is something that looks like a Python program, but has syntax errors in it, possibly because your e-mail program lost the indents. I don't know whether print (Data[1:6]) # TRY REMOVING THIS STATEMENT should be under while or not.

Hi. Problem has been resolved. The file had a bad record. However, just to note, the output in ubuntu Terminal was different to thonny when a print statement was removed. Not to worry, it's all good now. Thanks for you help, M.... Sent with [Proton Mail](https://proton.me/) secure email.
