Right. I was wondering what would happen in this case: s=[1,2,3] t=s s.clear() t # [] or [1,2,3]?? If you know your basic python it is "obvious" what would happen if you do s=[] or s[:]=[] instead of s.clear() and I guess it is equally "obvious" which one s.clear() must mimic. I'm still not used to dealing with mutable lists. Alan -- Defendit numerus -- http://mail.python.org/mailman/listinfo/python-list
