Access constraints for Python object-oriented members
Source: Internet
Author: User
There are corresponding keywords in Java, C ++, and PHP, such as public, protected, and private, but these keywords are not used in Python to declare the access scope of class members. In Python, a naming system is used to identify the approximate access range.
Class MyObjec (object ):
Username = "developerworks" # public
_ Email = "developerworks #163 #. com" # protected
_ Tel = "1391119 ****" # private
The code shows some clever naming methods.
All idioms starting with letters in python are automatically recognized as public by the python naming system. members starting with a single underline are recognized as protected, and those starting with a double underline are recognized as private. This is why python is concise and elegant.
