I. Introduction of ScrapyScrapy is an application framework written to crawl Web site data to extract structural data that can be applied to data mining, information processing, or storing historical data in some of the columns of the program. Scrapy was originally designed to crawl the web. Now, Scrapy has launched the python3.x version that has been promised.Why study Scrapy? It can be better for us to complete the crawler task, our own Python crawl

Use Python3 to create a TCP port scanner and a python3 Port Scanner In the initial stage of penetration testing, we usually need to collect information about attack targets, and port scanning is a crucial step in information collection. Through port scanning, we can find out which services are open to the target host, and even predict certain vulnerabilities based on the service. TCP port scanning is genera

Python3 learning notes: process distribution example, python3 learning notes I have been learning Python since Liao Da recently. The small example of distributed processes is interesting. Here is a record. Distributed Process The multiprocessing module of Python not only supports multi-process, but also supports multi-process distribution on multiple machines. A service process can be used as a scheduler to

Chapter 3 python3, python3 Python includes the following functions: Serial number Function Instance 1 List. append (obj)Add a new object at the end of the list 2 List. count (obj)Count the number of times an element appears in the list 3 List. extend (seq)Append multiple values in another sequence at the end of the list (extend the original list wi

Python3 generates a handwritten number, and python3 generates a handwritten number.0. Introduction Generally, verification codes are used for accessing the Internet, or in machine learning, you may have encountered issues such as Handwriting Recognition/verification code recognition. handwritten datasets are used; I tried to write a python program to generate a handwritten image. Here is an implementation m

Some basic Efficiency Improvement tips and Python3 tips for beginners in python3 Sometimes I ask myself why I don't know how to "do this" in a simpler way in Python 3. When I seek answers, over time, of course I found code that is more concise, effective, and with fewer bugs. In general (not just this article), the total number of "those" tasks exceeds what I imagined, but here is the first batch of non-obv

Python3 class and object: Collection, python3 object collection1. Combination 1. Method:In a new class definition, you can put the required class into the instance. Example: // Tortoise class Turtle: def _ init _ (self, x): self. num = x // Fish class Fish: def _ init _ (self, x): self. num = x // Pool class Pool: def _ init _ (self, x, y): self. turtle = Turtle (x) // combines the tortoise class into self.

Chapter 3 python3, python3 An anonymous function is a type of function or subroutine that does not need to define identifiers. Python uses lambda syntax to define anonymous functions. You only need to use expressions instead of declarations.Lambda syntax is defined as follows: lambda [arg1 [,arg2, ... argN]] : expression Sometimes, when passing in a function, you do not need to explicitly define the functio

Chapter 3 python3, python3 Note that the partial function here is different from the partial function in the mathematical sense. Partial function is introduced after version 2.5 and is part of functional programming. As we mentioned in the previous chapter, you can reduce the difficulty of function calling by setting the default value of the parameter. This can also be done by partial functions. Example: Th

Usage of super () and _ class _ in Python3, and python3 _ class _ The subclass accesses the attributes of the parent class with the same name, but does not want to directly reference the name of the parent class, because it may be modified at any time, so the data is retained only one copy. In fact, there is a better reason not to directly reference the name of the parent class. For details, see Python's su

Post sends json data on python3.x, and python3.xjson I. Summary During API automated testing, you often need to use python to send some interface messages with json content. If you use urlencode to parse the content and send a request, the server returns 200, OK status, but the response content is not readable (like a bunch of encrypted packets ). When locating the problem, we found that packet capture foun

Chapter 3 python3, python3 In python, the dictionary is another variable container model and can store any type of objects. Each key-value (key => value) pair of the dictionary uses the colon (:), And each pair is separated by a comma (,The entire dictionary is included in curly brackets ({}), The format is as follows: d = {key1 : value1, key2 : value2 } The key must be unique, but the value is not requir
