I am trying to write a function that copies a string parameter to the clipboard. I intend to use this in a Python script that I\'ve been working on. This is what I have
I suppose that you're running on Linux with Gnome.
That's normal behavior on Gnome, as soon as the source of the copy vanishes e.g. closing the Browser Window you copied from, the clipboard data gets removed too. Workaround is to install the gnome-clipboard-daemon
which will preserve the Clipboard state like Windows and KDE do.
So, there's not much you can do when running under Gnome, besides leaving your script running.
