Exercise

The organization of the classes is analog to the one of sheets.

X_Structure contains the to_str() method which writes the texts and answers of the Exercise to the output.

The instanciable Exercises should all be a copy of X_Model. They just need to reimplement __init__() (which first calls X_Structure.__init__() to set properly some fields) to define the Questions that will be embedded in the field questions_list.

Finally, each Exercise has also some global variables which should be defined. More details about them: (this should be checked again...)

• AVAILABLE_X_KIND_VALUES will define which kinds (and subkinds) of Exercises are handled by this class. Extract from the code:

  # Here the list of available values for the parameter x_kind='' and the
  # matching x_subkind values
  # Note : the bypass value allows to give the value of *x_subkind* directly to
  # the matching question Constructor, bypassing the action of the present class
  AVAILABLE_X_KIND_VALUES = \
      {'short_test' : ['x_subkind1', 'x_subkind2'],
       'preformatted' : [''],
       'bypass' : ['']
      }
  

• X_LAYOUT_UNIT: will define the unit used in X_LAYOUTS

• X_LAYOUTS: will define the layout of the Questions inside the Exercise

The instructions for use are all written in X_Model.py
