If a container defines __str__, it can do whatever it wants with items inside itself. If the container doesn't define __str__ (or defines it as an alias to __repr__), then __repr__ will be used, and the only sensible thing to do is call repr() on the elements inside it. If you want containers to have a 'prettier' format when passed to str(), give them a __str__ that does the pretty thing. Me, I don't see the point of having a 'pretty' format for lists that is ambiguous. If I want to print a list, 'repr' does what I expect. Or, I loop over the list and print each element how I expect it to print. I don't see the value in str(['1', 1, '1, [1]', '1]', '\n[1']) giving hard to understand output. -- Thomas Wouters <[EMAIL PROTECTED]> Hi!
