Restarting a self-updating python script

Question

I have written a script that will keep itself up to date by downloading the latest version from a website and overwriting the running script.

I am not sure what the

Answer 1

You can use reload(module) to reload a module.

Answer 2

I think the best solution whould be something like this:

Your normal program:

...

# ... part that downloaded newest files and put it into the "newest" folder

from subprocess import Popen

Popen("/home/code/reloader.py", shell=True) # start reloader

exit("exit for updating all files")

The update script: (e.g.: home/code/reloader.py)

from shutil import copy2, rmtree
from sys import exit

# maybie you could do this automatic:
copy2("/home/code/newest/file1.py", "/home/code/") # copy file
copy2("/home/code/newest/file2.py", "/home/code/")
copy2("/home/code/newest/file3.py", "/home/code/")
...

rmtree('/home/code/newest') # will delete the folder itself

Popen("/home/code/program.py", shell=True) # go back to your program

exit("exit to restart the true program")

I hope this will help you.
