Python download updated code and apply it to itself (zip)

[Joveice]

How can I make a python program download a new version of itself and apply it? I thought about just downloading the zip file and overwriting itself, but this will fail as it's already running the .exe file right?

 

So whats the best way to do this where the user to select "download now" and it overwrites everything with the new code and then etc restarts or something.

You can download a new version, extract it somewhere and trigger a restart of the app so that on launch it would see/check for newer files.

Most apps that have an automatic updater usually have a separate app built for the updating process. This update app would compare the installed version to the newest one available, and if there was an update it would close out the app in question, download the newest version, overwrite the current files with the newer ones, then restart that app.

If it's in Python, you would write a Python script to be called when the user checks for an update, which would kill the original app and do as I described above.

Thanks, I like this approach.
