Python offers mutable (can be changed) and immutable (can't) objects (remember: 'everything is an object'): https://docs.python.org/3/reference/datamodel.html?highlight=mutable%20data
While that's true, it's actually irrelevant to this situation.
$ a = "bob" $ b = a $ b = "bert" $ a 'bob'
Here, you're not even attempting to modify the object that is bound to b; instead, you're rebinding the name b to a different object. Whether the object to which b was previously bound is mutable or not makes no difference. You can see this if you do the equivalent thing with lists: >>> a = ["alice", "bob", "carol"] >>> b = a >>> b ['alice', 'bob', 'carol'] >>> b = ['dave', 'edward', 'felicity'] >>> a ['alice', 'bob', 'carol'] >>> b ['dave', 'edward', 'felicity'] -- Greg -- https://mail.python.org/mailman/listinfo/python-list
