You can test your newfound knowledge by predicting the output of the following script: a = [1, ["x", "y"], 3] b = a[:] a[1][1] = "hello!" print(a) # [1, ['x', 'hello!'], 3] print(b) # what will that print? Think twice before you answer. What is copied, what is referenced? _______________________________________________ Tutor maillist - Tutor@python.org To unsubscribe or change subscription options: https://mail.python.org/mailman/listinfo/tutor
