Restart python script itsself (run again).md

Inspired from https://blog.petrzemek.net/2014/03/23/restarting-a-python-script-within-itself/

def restart():
        import sys
        print("argv was",sys.argv)
        print("sys.executable was", sys.executable)
        print("restart now")

        import os
        os.execv(sys.executable, ['python'] + sys.argv)

Works like a charm (--a pycharm?)! I am running a discord bot that I quite frequently manage, and having a command like this is extremely helpful! I've looked everywhere and this is the only one that's worked so far! One thing that I'd change just for optimization's sake:
['python'] + sys.argv -> ['python', sys.argv] as the + operator is not optimized for this purpose in python...
nevermind, it doesn't work if you do that... Do you know why that happens @plieningerweb?

@Techtiger255 Because that's not how you concatenate lists in python:

>>> my_list = ['foo', 'bar']

>>> print(['spam', my_list])
['spam', ['foo', 'bar']]

>>> print(['spam'] + my_list)
['spam', 'foo', 'bar']

>>> ['spam', my_list] == ['spam'] + my_list
False

Alternatively, you could do my_list.extend(['spam']), however this modifies my_list and might not be what you want.

I'm getting connectionRefusedError: [WInError 10061], anyone know why?

Thank you for this!

thanks for this information dude! it's working for my project, thanks again.

Amazing, thank you!

Seems like the input function is broken with it tho...

if you want to run/restart your script with -i its not working

Wouldn't it make more sense to not hardcode the executable name?

import os, sys
def restart():
    os.execv(sys.executable, [os.path.basename(sys.executable)] + sys.argv)

Thanks! Works great!
