You should generally avoid CamelCase for function and instance names in Python code. CamelCase should be used for class names. PEP 8 is a good style reference: http://www.python.org/dev/peps/pep-0008/ > I use IPython for that purpose.

You most likely want to use __str__ and/or __unicode__. http://docs.python.org/reference/datamodel.html#object.__str__ I suggest reading this page: http://stackoverflow.com/questions/1307014/python-str-versus-unicode The Python documentation doesn't seem to cover __unicode__ very well... __repr__ may also be of interest. > When I print out for example a transaction i want to print out information of > objects that are nested into it.
