Python class attribute is a function that comes with the language. This article will explain through example analysis what Python class function is, and how to use Python to access attributes .
1.Python class attributesare:
1.__dict__: Attributes of the class (contains a dictionary consisting of data attributes of the class)
2.__doc__: Documentation string of the class
3.__name__: Class Name
4.__module__: The module where the class definition is located (the full name of the class is '__main__.className', if the class is located in an imported module mymod, then className.__module__ is equal to mymod)
5.__bases__: All parent class elements of the class (contains a tuple composed of all parent classes)
2.So how to go How about using Python to access attributes?
We can use the period . to access the properties of the object. Use the following class name to access class variables:
emp1.displayEmployee() emp2.displayEmployee() print "Total Employee %d" % Employee.empCount
Contact one and two, let’s give an example
#!/usr/bin/python # -*- coding: UTF-8 -*- class Employee: '所有员工的基类' empCount = 0 def __init__(self, name, salary): 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__
The output result of executing the above code is as follows:
Employee.__doc__: 所有员工的基类 Employee.__name__: Employee Employee.__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>}

This tutorial demonstrates how to use Python to process the statistical concept of Zipf's law and demonstrates the efficiency of Python's reading and sorting large text files when processing the law. You may be wondering what the term Zipf distribution means. To understand this term, we first need to define Zipf's law. Don't worry, I'll try to simplify the instructions. Zipf's Law Zipf's law simply means: in a large natural language corpus, the most frequently occurring words appear about twice as frequently as the second frequent words, three times as the third frequent words, four times as the fourth frequent words, and so on. Let's look at an example. If you look at the Brown corpus in American English, you will notice that the most frequent word is "th

PDF files are popular for their cross-platform compatibility, with content and layout consistent across operating systems, reading devices and software. However, unlike Python processing plain text files, PDF files are binary files with more complex structures and contain elements such as fonts, colors, and images. Fortunately, it is not difficult to process PDF files with Python's external modules. This article will use the PyPDF2 module to demonstrate how to open a PDF file, print a page, and extract text. For the creation and editing of PDF files, please refer to another tutorial from me. Preparation The core lies in using external module PyPDF2. First, install it using pip: pip is P

mPDF
mPDF is a PHP library that can generate PDF files from UTF-8 encoded HTML. The original author, Ian Back, wrote mPDF to output PDF files "on the fly" from his website and handle different languages. It is slower than original scripts like HTML2FPDF and produces larger files when using Unicode fonts, but supports CSS styles etc. and has a lot of enhancements. Supports almost all languages, including RTL (Arabic and Hebrew) and CJK (Chinese, Japanese and Korean). Supports nested block-level elements (such as P, DIV),
