Curses could not find terminal

[Gribouillis]

You have launched a fork bomb. You'd better shutdown and reboot. It's not the three lines you just posted that open and close many terminals. Can you post the real code?

Here is a full code that works for me in linux, but the terminal application is konsole, which has its own options

import argparse
import subprocess
import sys

def main_work(args):
    print('Hello from term-example')

def main():
    parser = argparse.ArgumentParser()
    parser.add_argument(
        '--noterminal',
        help="don't start a new terminal'",
        action='store_true')
    ns = parser.parse_args()
    try:
        sys.stdout.fileno()
    except Exception:
        # not a terminal for sure
        if ns.noterminal:
            raise RuntimeError('Need a terminal to run.')
        else:
            subprocess.call(['konsole', '--noclose', '-e', sys.executable, __file__, '--noterminal'])
    else:
        main_work(ns)

    
if __name__ == '__main__':
    main()

When I run this code in a terminal, it simply executes the code in main_work(). When I run it from IDLE3 by pressing the F5 key, it launches a new console and executes the code from main_work() in this console.

The konsole command has an option --noclose so that it stays here after the execution of
the code. An alternative is to add a command that waits at the end, such as if ns.noterminal: input()
