			0 ignored issues – show Coding Style introduced 2017-08-24 11:14 UTC by Report Bug Copy Issue Report Usage of the `global` statement should be avoided. Usage of `global` can make code hard to read and test, its usage is generally not recommended unless you are dealing with legacy code. Loading history... Coding Style Naming introduced 2017-08-24 11:14 UTC by Report Bug Copy Issue Report The name `settings` does not conform to the constant naming conventions (`(([A-Z_][A-Z0-9_])\|(__.__))$`).

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. Loading history...

Prefixing a member variable `_` is usually regarded as the equivalent of declaring it with protected visibility that exists in other languages. Consequentially, such a member should only be accessed from the same class or a child class: class MyParent: def __init__(self): self._x = 1; self.y = 2; class MyChild(MyParent): def some_method(self): return self._x # Ok, since accessed from a child class class AnotherClass: def some_method(self, instance_of_my_child): return instance_of_my_child._x # Would be flagged as AnotherClass is not # a child class of MyParent Loading history...
