What is a Python class property? How do I access properties with Python?

Python class Propertiesis a function of the language itself, this article will explain through the example of what is Python class letters,and how to use Python access properties.

A. The Python class properties are:

1.__DICT__: Properties of the Class (contains a dictionary, consisting of the data properties of the Class)

2.__DOC__: Document string for Class

3.__NAME__: Class name

4.__MODULE__: The module where the class definition resides (the full name of the class is ' __main__.classname ', if the class is in an import module mymod, then classname.__module__ equals Mymod)

5.__BASES__: All parent classes of a class make up elements that contain a tuple of all the parent classes

two. So how do you go about accessing properties with Python ?

We can use the dot number. To access the properties of the object. Access the class variable using the name of the following class:

Emp1.displayemployee () Emp2.displayemployee () print "Total Employee%d"% Employee.empcount

Contact one, two, let's give an example

#!/usr/bin/python#-*-Coding:utf-8-*-class Employee:   ' base class for all employees '   empcount = 0    def __init__ (self, name, Sala RY):      self.name = name      self.salary = Salary      Employee.empcount + =      1 def displaycount (self):        print "  Total Employee%d '% employee.empcount    def displayemployee (self):           print "Name:", Self.name,  ", Salary:", Self.salary print "employee.__doc__:", employee.__doc__ print "employee.__name__:", employee.__name__ print "Employee. __module__: ", employee.__module__ print" employee.__bases__: ", employee.__bases__ print" employee.__dict__: ", employee.__dict__

Execute the above code to output the result as follows:

employee.__doc__: base class for all employees employee.__name__: employeeemployee.__module__: __ Main__employee.__bases__: () employee.__dict__: {' __module__ ': ' __main__ ', ' displaycount ': <function displayCount at 0x10a939c80>, ' Empcount ': 0, ' displayemployee ': <function displayemployee at 0x10a93caa0> ' __doc__ ': ' \xe6\ X89\x80\xe6\x9c\x89\xe5\x91\x98\xe5\xb7\xa5\xe7\x9a\x84\xe5\x9f\xba\xe7\xb1\xbb ', ' __init__ ': <function __init __ at 0x10a939578>}
