Coding problemsBecause it involves Chinese, it inevitably involves the problem of coding, this time to take this opportunity to be thoroughly understood.The problem is to start with the encoding of the text. The original English code is only 0~255, just 8-digit 1 bytes. In order to express a variety of different languages, it is natural to expand. Chinese words have GB series. Maybe you've heard of Unicode and UTF-8, so what's the relationship between them?Unicode is a coding scheme, also known

ABC is a class that cannot be instantiated. Python 3 Adds a new framework-abc-it provides support for ABC. This ABC module has a meta class ( ABCMeta ) and modifier ( @abstractmethod and @abstractproperty ). If an ABC has one @abstractmethod or @abstractproperty , it cannot be instantiated, but must be overridden within a subclass. For example, the following code:#-*-coding:utf-8-*- fromAbcImportAbcmeta,abstractmethod#Abstract classclassA (object):__

Subclasses can not override __init__, and when instantiating subclasses, the defined __init__ in the superclass are called automaticallyIt means subclasses don't write __init__.A __foo that begins with a double underscore represents a private member of a class__FOO__ represents special method-specific identifiers in PythonA class attribute that begins with a single underscore, which is not directly accessib

Inheritance of classes and overloading of methodsThe above is defined by a Class A, and then by the definition of a class B,b inherits the Class A, so that B has a non-private properties and methods.1 classWasher:2company='ZBL'3def __init__ (self,water=Ten, scour=2):4Self._water=water #不想让用户直接访问实例变量, can be marked as private5Self.scour=Scour6Self.year= -#这是生产日期7 #属性包装, wraps the water property into a method
