Solve the following python programming problem given the following code:
def AssignmentExpression(traverser, node) : 
    traverser._debug ('ASSIGNMENT_EXPRESSION') 
    traverser.debug_level += 1 
    traverser._debug ('ASSIGNMENT>>PARSING RIGHT')

    traverser._debug ('ASSIGNMENT>>PARSING LEFT') 
    orig_left = left = traverser.traverse_node (node ['left']) 
    operator = node ['operator'] 
    def set_lvalue(value) : 
        node_left = node ['left'] 
        traverser._debug (('ASSIGNING:DIRECT(%s)' % node_left ['type'])) 
        global_overwrite = False 
        readonly_value = True

traverser._declare_variable (node_left ['name'], value, type_ = 'glob')

            if (node_left ['type'] == 'MemberExpression') : 
                member_object = MemberExpression (traverser, node_left ['object'], instantiate = True) 
                member_property = _get_member_exp_property (traverser, node_left) 
                traverser._debug (('ASSIGNMENT:MEMBER_PROPERTY(%s)' % member_property))
