Hello all, Behold:
---------- a = [ 'Foo', 'Bar' ] b = [ 'Boo', 'Far' ] q = [ a, b ] print q[0][0] print q[1][1] a[0] = 'Snoo' b[1] = 'Gnuu' print q[0][0] print q[1][1] ---------- This will output: Foo Far Snoo Gnuu I assume it does so because q stores _references_ to a and b. How would do I do if I want to copy the list? I.e. I want the output from the code above to be: Foo Far Foo Far ..even if a[0] = 'Snoo' and b[1] = 'Gnuu' remain where they are. Or, better yet, how do I store a and b in q, and then tell Python that I want a and b to point to new lists, without touching the contents in q? C equivalent of what I want to do: ----------- a = calloc(n, size); prepare(a) q[0] = a; a = calloc(n, size); // new list; 'q' is unaffected if I change 'a' ----------- -- http://mail.python.org/mailman/listinfo/python-list
