I suggest adding a "Copy variable to clipboard" menu option to the edit menu of IDLE.

Sometimes I need to copy a variable to clipboard, but because the variable is so long, printing it in the IDLE window makes IDLE sluggish and then selecting and copying the printed value becomes a little cumbersome.

Of-coarse as it is suggested in [1], I can do copy the variable `v` using the following commands:

from Tkinter import Tk
r = Tk()
r.withdraw()
r.clipboard_clear()
r.clipboard_append(str(v))
r.destroy()

but I think it's too much and it would be nice to have such menu option that after clicking on it a dialog box appears asking for variable name and after entering the name causes the str content of the variable to be copied to the clipboard.
