Hey @IR21-cyber, thanks for reporting. Could you post the script you're running which fails to produce output? In case it's too complex, please post the simplest version you can of it.

That will help us to reproduce your problem on our side. Otherwise we won't be able to help you.

Hi @ccordoba12, thank you for your reply. Actually I figured it out yesterday. I had these lines at the beginning of my script:

try:
s = sys.winver
os.system("cls")
except:
os.system("clear")

and after I disabled them, everything worked. But I think it is a little bit weird, that the output on the console was cleared after running the script since the lines were placed at its beginning.

Can you give any advice how am I supposed to clear the console before running the script?

@IR21-cyber, ok, I understand better your problem now. You said:

Can you give any advice how am I supposed to clear the console before running the script?

The mechanism we offer for that is to run the script in a dedicated console. To do that, you need to go to the menu

Run > Configuration per file

and select Run file with custom configuration and then Execute in a dedicated console. That will always clear the console before running your code.

That should solve your problem, but let us know if it is what you're looking for.
