The script used to run normally at startup but have failed since I added the

random

function to randomise script launching from Luma Examples.

Here's the part from the script that is failing

def run_ext():     i = 0     while True:         try:             # Command to run "OTHER".py             ####random_file=random.choice(os.listdir())             Local_List = [each for i, each in enumerate(os.listdir(current_working_directory)) if each.endswith('1.py')]             random_py = random.choice(Local_List)             random_py = current_working_directory + '/' + str(random_py)             print(random_py)             sp.run(random_py, timeout=10)         except sp.TimeoutExpired:             break  

When introducing i to

random_py = random.choice(Local_List[i])

, I get this following error:

Can someone teach me how to fix this issue and what's the best way to have this script work as expected: pick a random example from the Luma Examples folder and run it for x seconds then go on with the rest of the main(). Worth noting that this same script run normally without error when lunched from Geany.
