I'm trying to create a python script to convert into exe which just deletes itself. When I run it as .py file it works. The code is this:

import os
os.remove(os.getcwd + "\\test.py")

I'm working in Windows that's why I'm using \\ and the file is obviously named test.py. But when I convert it into an exe file (I've tried both with py2exe and pyinstaller) it gives me access denied error. Does anyone know how to fix this?

PS: Yes, I've changed the name to test.exe if you're asking.

It won't be this simple. 1) When you are running the script actually it is the python.exe executing the statements and the script file (test.py) is free. In this way python.exe can delete the script. 2) When you convert convert your script to exe, it is the exe file itself executing, which means the file is 'busy', or said in other words - used by the process, and it cannot be deleted.

Find a way to start another process, which would delete the file after you exit the current process.

Edit(sample code): 


import sys
import ctypes
import platform
import subprocess


def execute(command, async=False):
    """
    if async=False Executes a shell command and waits until termination and

    returns process exit code
    if async=True Executes a shell command without waiting for its 
    termination and returns subprocess.Popen object
    On Windows, does not create a console window.
    """
    if async:
        call = subprocess.Popen
    else:
        call = subprocess.call



if platform.system() == 'Windows':
    # the following CREATE_NO_WINDOW flag runs the process without 
    # a console window
    # it is ignored if the application is not a console application
    return call(command, creationflags=0x08000000)
else:
    return call(command)




def main():


ctypes.windll.user32.MessageBoxA(0, __file__, 'Show path', 0)
ctypes.windll.user32.MessageBoxA(0, sys.executable, 'sys.executable', 0)

with open(r'D:\delete_me.py', 'w') as f:
    f.write('import os\n')
    f.write('import time\n')
    f.write('time.sleep(2)\n')
    f.write('os.remove(r"{}")'.format(sys.executable))

execute(r'C:\Python27\python.exe D:\delete_me.py', async=True)

if __name__ == '__main__': main()

And this was compiled with `pyinstaller.exe --onefile --windowed D:\self_delete.py

execute function is something we use to execute calls on both Linux and Windows and I just copied it. This is why the platform check is there. You can use some .bat file with timeout instead of sleep or whatever else you want if you can't execute delete_me.py
