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

Ezio Melotti <ezio.melotti@gmail.com> added the comment:

FWIW it's pretty much the only way of saying what it means.

However, even using "not deep" here would still be ambiguous. What's a deep copy? What's a non-deep copy? Using "shallow" might be a problem, but the real problem is that regardless of the wording, the reader might not know what this is all about. ---------- _______________________________________ Python tracker <report@bugs.python.org> <http://bugs.python.org/issue14112> _______________________________________
