Thank you David, for answering to all this question.
The program gwydump helped a lot too!
One precision, for example to change the max that is a double value one has
to do:
container.set_double_by_name<http://gwyddion.net/documentation/head/pygwy/gwy.Container-class.html#set_double_by_name>
("/0/max", value) .
As "/0/max" was a string I was trying to use
container.set_string_by_name<http://gwyddion.net/documentation/head/pygwy/gwy.Container-class.html#set_double_by_name>
("/0/max", value) .
