How to make Python restart its own process?

To reboot its own process in Python, you can use the os.execv() function. This function replaces the current process with the specified program and does not return.

Here is a sample code demonstrating how to restart a Python process using the os.execv() function.

import os
import sys

def restart_program():
    python = sys.executable
    os.execl(python, python, *sys.argv)

if __name__ == "__main__":
    restart_program()

In the above code, the function restart_program() uses sys.executable to get the path of the current Python interpreter, and then uses os.execl() to replace the current process with a new Python process. Since os.execl() replaces the current process, any code after it will not be executed.

Please make sure you have handled all the data that needs to be saved before calling the restart_program() function, as restarting the process will result in the loss of all current data and state.
