Function still running after using os._exit() command

Python Help
1

I’m making a text-based rpg right now, and I have just gotten completely stumped from my main menu quit option just completely not working, and I cannot find a single reason why, I slammed it into chatgpt like 20 times to see if it could find the issue, and it said its unusual. It also specifically happens after you’ve gone through a battle atleast one time, but when you have yet to play the game once, it quits as intended. Also probably worth noting is that this is using the default python from replit.com

the loading_screen() function referenced in the main menu just uses the time.sleep() function to do a “…” after you enter the parameter for a quote

loading_screen() function, in case it finds itself being a problem

def loading_screen(seconds, quote):
  print(quote, end="", flush=True)
  for _ in range(seconds):
    time.sleep(0.5)
    print(".", end="", flush=True)
  print()

savegame() function

def savegame():
  global damageThisBattle
  global itemsUsed
  global playerExperience
  global experienceToNextLevel
  global currentLevel
  global ogresKilled
  global skeletonsKilled
  saveFile = open("savestates.txt", "r+")
  lines = saveFile.readlines()
  saveFile.seek(0)  
  # Move the cursor to the beginning of the file

  ogresKilled = ogresKilled + int(lines[0].strip())
  skeletonsKilled = skeletonsKilled + int(lines[1].strip())
  totalDamage = int(lines[2].strip()) + damageThisBattle
  totalItemsUsed = int(lines[3].strip()) + itemsUsed

  # Update the lines with the new values
  saveFile.write(str(ogresKilled) + "\n")
  saveFile.write(str(skeletonsKilled) + "\n")
  saveFile.write(str(totalDamage) + "\n")
  saveFile.write(str(totalItemsUsed) + "\n")
  saveFile.write(str(currentExperience) + "\n")
  saveFile.write(str(currentLevel) + "\n")

  # Truncate the file in case the new content is smaller     
  # than the old content
  saveFile.truncate()

  saveFile.close()

Main menu code ran in a loop where the other condition is (if inBattle == True:)

    while playInput not in validPlayInputs:
      printMainMenu()
      playInput=input("\n1. Play\n2. Check Save\n3. Wipe save"
                      "\n4. Quit\n")
      if playInput=="1":
        loadgame()
        if newGame==False:
          loading_screen(3,"Loading Save")
          loading_screen(3,"Starting game")
          print("")
          print("")
        else:

UPDATE:
I’ve run the code in PyCharm community edition as well to make sure it wasn’t replit.com causing the issue, and it happens on PyCharm as well. It is running python version: 3.11

UPDATE 2:
I believe I have solved the issue, and it was caused by the restart_program() function, which I’ve now updated to instead actually return the player to the main menu through breaking of the loop.

the new code in which the updated lines are relatively close to the bottom, before the main menu loop:

That’s your problem (also in your updated code - though I didn’t look at that carefully). First of all, starting a subprocess call of python inside a python script - that’s a big red flag. I cannot think of any scenario – in normal straight-forward programs like this – where this would ever be necessary. (Btw if you do call subprocess you should also at least check its exit code instead of ignoring that.) Second, calling os._exit is a yellow flag. If you want to exit, you should normally use sys.exit, since os._exit is a hard exit that doesn’t do any resource cleanup (even if really needed).
Then, the way the program exits is wrong when used in combination with restart:

elif playInput=="4":
        loading_screen(3,"Quitting")
        os._exit(0)

This will just exit from the subprocess, so the main python will keep running! You can debug and verify this by a skeleton version of your program:

import subprocess
import os
import sys

def restart():
    python = sys.executable
    subprocess.call([python] + sys.argv)

print("Running", os.getpid())

while True:
    cmd = input(">>> ")
    if cmd == "q":
        print("Exiting", os.getpid())
        sys.exit(0)
    else:
        restart()

Now, I can see why you added that restart function. The reason is that you have all those globals which need to be reset. Using such a ton of globals is also a pretty big red flag in the code.

So to fix I suggest:

  • get completely rid of restart
  • either: get rid of all globals, replace them by objects and object attributes(instances of custom classes like Player, Weapon, and attributes of given objects) that track the game state (objects can easily be re-created or reset when you want to restart); or keep the globals, but add a proper initiailization/reset function to reset them to defaults when a restart is needed; instead of restarting with a new process, you would then just reset the state – staying in the same process

Using an OO (object oriented)-approach (with custom classes) will make your script way more readable and maintainable and will also make it a lot easier to change it into a real multi-player kind of game for instance.

Here are a few assignments that you might try to improve the code. I think you’ll be very happy with the results; it should make the code much easier to follow and understand - and the user interface will look more consistent, too.

First, try using more functions to split up the work in the main loop. For example, try making a function for the entire while inBattle==True: loop, and figure out what information needs to be passed and returned to make that work. Try to use functions/arguments and the return value, instead of global variables.

Try making a different function to print whatever text for the menu header. Have it take two parameters: the middle text (here, that would be "Epic Battle Simulator"), and a box width (40 in this case). Hint: with the .format method to format strings, you can tell it to “center-justify” text within a field, and set a field width dynamically:

>>> '{:10}'.format('text') # the 10 is a width
'text      '
>>> '{:^10}'.format('text') # the ^ means to center
'   text   '
>>> '{:^{}}'.format('text', 10) # nest the {} to give the width separately
'   text   '

(Bonus: instead of just taking a string to center, have it take a list of strings, that will show up one per line. Keep in mind that the calling code will have to know how to handle that. You could also try passing the lines as separate arguments, using *args.)

Try making a function that creates a “generic” bar, by telling it a “label” as well as the current and maximum values. (You’re almost there with enemyStatusBar already). Try making it return the bar text, instead of printing it, and let the calling code do the printing instead. Use this three times to create the bars for playerStatusBars instead of repeating the logic, and have it return either a list of the bars to print, or a single string (joined up with newlines). Let the calling code do the printing for that, too.

Try making a generic function for a menu, like so (I’ve used comments and a docstring to explain what it needs to do):

def do_menu(header, options):
    """Repeatedly show the menu and ask for an input
    until something valid is chosen. Returns an integer for the choice.
    header -> a string to show before the options
    options -> a list of strings for menu options, without number labels
    """
    # Have an outer loop that will repeat until the input is valid
    # Your choice: show the header only once, or at the top of the loop
    # Have an inner loop that shows each option, one per line, and numbers them
    # Prompt for input and test it:
    # if it can be converted to an integer in range, return that
    # if it matches one of the options, return the corresponding integer
    # (hint: try using another inner loop to check the option text)
    # otherwise, keep trying

Then see about using that to replace the other parts of the code that handle menus.

(Bonus: if you made the box-printing function from above, try using it to put the header in a box always.)
