The name
items_history_list does not conform to the constant naming conventions ((([A-Z_][A-Z0-9_]*)|(__.*__))$ ).
This check looks for invalid names for a range of different identifiers. You can set regular expressions to which the identifiers must conform if the defaults do not match your requirements. If your project includes a Pylint configuration file, the settings contained in that file take precedence. To find out more about Pylint, please refer to their site.
