== Why is this an issue? Shared naming conventions allow teams to collaborate efficiently. This rule raises an issue when a method name does not match a provided regular expression. For example, with the default provided regular expression ``++^[a-z_][a-z0-9_]*$++``, the method: [source,python] ---- class MyClass: def MyMethod(a,b): # Noncompliant ... ---- should be renamed to [source,python] ---- class MyClass: def my_method(a,b): ... ---- ifdef::env-github,rspecator-view[] ''' == Implementation Specification (visible only on this page) include::../message.adoc[] === Parameters .format **** _STRING_ ---- ^[a-z_][a-z0-9_]*$ ---- Regular expression used to check the [method|function|subroutine] names against **** ''' == Comments And Links (visible only on this page) include::../comments-and-links.adoc[] endif::env-github,rspecator-view[]
