Thank you everybody for the contributions and sorry if I reawoke the recurring "is vs ==" issue. I -think- I understand how Python's object model works, but clearly I'm still missing something. Let me reiterate my original example without the distracting aspect of the "==" comparisons and the four variables:
>>> a = "a" >>> b = "a" >>> a is b True >>> a = "/a" <- same as above, except the forward slashes! >>> b = "/a" <- same as above, except the forward slashes! >>> a is b False So, it appears that in the first case a and b are names to the same string object, while in the second case they are to two separate objects. Why? What's so special about the forward slash that cause the two "/a" strings to create two separate objects? Is this an implementation-specific issue?
