Tuples & lists

I'm a new user and Python looks great.

Why both having tuples and lists? As far as I can see there're the same, but
tuples are read only..? Have I missed something in the tutorial?

Also, has anyone written a tcl/tk dialog/resource editor type thing so you
could save a form out as code? Could save a lot of time...

Thanks,
Nick.

There is probably something in the the FAQ. BAsically, tuples are stored
more compactly and can be used as dictionary keys (because they ARE
readonly).

Did an experiment on NT and lists and tuples took the same amount of space.
Humm ? Not what I expected.
