Differences between _, _ and _ xx _ in python"_" Single-underline Python does not have a real private method. To implement a private method similar to a method in c ++, you can add an underscore (_) before the method or attribute of the class, which means that the method or attribute should not be called and does not belong to the API. This problem often occurs when using property: class BaseForm (StrAndUnicode ):... def _ get_errors (self): "Returns
