How to prevent python from auto closing the terminal


I created a CLI with python and built it as a exe with pyinstaller. When I double click the exe the terminal opens and if my code encounters few condition it will display some warning message and do sys.exit(). on sys.exit() the terminal closes automatically. So I cant even read that warning message. It also happens with os.system('cls'). But when I open an empty terminal and then run my exe (/my_app>./my_app.exe) it works fine and os.system('cls') works too. It only happens when I double click the exe to run

if some_condition == False:
    sys.exit()

Solution

  • You can modify your code to pause before exiting. This will allow you to see any messages before the terminal window closes.

    # ... your existing code ...
    
    if some_condition == False:
        print("Your warning message here")  # Display your warning message
        input("Press Enter to exit...")     # Wait for user input before exiting
        sys.exit()
    
    # ... rest of your code ...
