What part of "CPython implementation detail" was too difficult for you to understand? id() is not an addressof function. It returns, and I quote: "an integer which is guaranteed to be unique and constant for this object during its lifetime" which is *not the case for memory addresses*. Here are the IDs of a few objects in Python: steve@orac:~$ jython -c "print id(None); import sys; print id(sys)" 1 2 steve@orac:~$ ipy -c "print id(None); import sys; print id(sys)" 0 43 Are you going to argue that these are memory addresses? If not, what relevance do you think the id() function has here? Note: when I write my own Python implementation, all IDs will be negative odd numbers. -- Steven -- https://mail.python.org/mailman/listinfo/python-list
