Guido van Rossum aee5e26f4b Add warning that mutable argument defaults are evaluated only once; ... with examples and workaround. This keeps coming up, and I believe that this section in the tutorial may have been (in part) the source of the confusion. While it didn't show examples with [] for a default, it also didn't emphasize enough why that would be a bad idea, and while it did say that defaults are evaluated at the point of function definition, the example was not relevant for this issue.		1998-08-07 17:45:09 +00:00
