python class docstring

It's not long enough to touch the Python language, and many of the features of the language are not well understood, and many usages are not yet known. Today I want to write a function call in the inheritance of Python object-oriented programming. Share it and make progress together.Because of previous exposure to Java and C + +, all of the ideas for object-oriented are already well-known. There is no longe

variables and cannot access instance variables. When we directly access the initialized instance variable, we are prompted without this attribute (Attributeerror:type object ' ClassName ' has no attribute ' arg '). 1 classClassName (object):2 """docstring for ClassName"""3 4Name ='Pig' #This is a class property5 6 def __init__(Self, arg):#Init initializes the instance properties and instan

How to obtain the list of class attributes in Python, and obtain class attributes in python Preface In my recent work, I have encountered a need to obtain a static attribute of the class, that is, there is a class Type, and I want

. When a reference is passed to a function, the function automatically copies a reference, and the reference in the function does not have a semi-gross relationship with the outside reference. So the first example is that the function refers to an immutable object number, and when the function returns, the outside reference does not feel half-hairy. And the second example is different, The reference in the function refers to the Mutable object list, which points to the memory address of the

The use and difference of class method, class instance method, static method in Python2011-03-24 11:58:06| Category: Python | Tags: Python class method static method | report | Font size SubscriptionTransfer from http://stonelee.javaeye.com/blog/726449How to use:

Note: The Python2.7 is used. One, instance method An instance method is a method that an instance of a class can use. As follows: Copy Code code as follows: Class Foo: def __init__ (self, name): Self.name = Name def hi (self): Print Self.name if __name__ = = ' __main__ ':foo01 = Foo (' Letian ')Foo01.hi ()Print type (Foo)Print type (FOO01)Print ID (foo01)Print ID (Foo) The

Attributes are divided into instance properties and class propertiesMethods are divided into ordinary instance methods, class methods, static methodsBoth static and class methods of Python can be accessed by a class or instance, and the difference is obvious:1) Static method

can force some of the attributes that we think must be bound to be filled in when the instance is created. By defining a special __init__ method, when creating an instance, bind the attributes such as Name,score: Class Ren (): def __init__ (self,name,sex): Self.name = Name self.sex = Sex def hello (self): print (' Hello {0} '. Format (self.name)) test = ren (' yangling ', ' M ') Test.hello ( The results are printed as:Explain: 1. When passing para

A few days ago to do a project, meet a similar problem. The parent class is a common class, which is used in many sub-projects, and subclasses are used as a basic class in many parts of the project, but there are some class attributes in the original parent class (note that

In this article let's look at the knowledge about classes, some friends may have just come into contact with the Python programming language, for Python class PropertiesThis is not a special understanding, but it's okay. The next article will come to take you to learn Python Class
