The name
NAME does not conform to the attribute naming conventions ((([a-z][a-z0-9_]{2,30})|(_[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.

Escape sequences in Python are generally interpreted according to rules similar to standard C. Only if strings are prefixed with
r
orR
are they interpreted as regular expressions.The escape sequence that was used indicates that you might have intended to write a regular expression.
Learn more about the available escape sequences. in the Python documentation.
