[docs] [issue14112] tutorial intro talks of "shallow copy" concept without explanation

Raymond Hettinger <raymond.hettinger@gmail.com> added the comment: How about we just like "shallow copy" to the copy module docs. That way, a person can follow-up with more detail if they're interested, yet still can read-on without interruption if they choose (this entry occurs *very* early in the tutorial). ---------- _______________________________________ Python tracker <report@bugs.python.org> <https://bugs.python.org/issue14112> _______________________________________
