[docs] [issue30826] More details in reference 'Looping through a list in Python and modifying it'

Terry J. Reedy added the comment: I agree that the tutorial For section needs be updated to include non-sequences. A dict example will help with that. I agree that the unrealistic insert mis-directs attention and like Raymond's replacement. ['users.copy()' should be 'users.copy().items'] ---------- versions: +Python 3.7 _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue30826> _______________________________________
