Python implements parallel capturing of 0.4 million house price data for the entire site (can be changed to capture the city), python captures Preface This crawler crawls house price information to practice data processing and whole-site crawling over 0.1 million. The most intuitive way to increase the data volume is to increase the functional logic requirements. For Python features, carefully select the data structure. In the past, even if the logic

Using Python to capture administrative area code, python captures Preface The National Bureau of Statistics website has relatively consistent Administrative Code. For some websites, this is a very basic data, so I wrote a Python program to capture this part of the data. Note:After capturing it, you need to organize it manually. Sample Code: #-*-Coding: UTF-8-*-''' obtain the administrative division code ''' import requests, rebase_url = 'HTTP: // java

waste too much time. In order to reduce the computational time, the CRC check code is generally not used, but a simpler internet checksum (internetchecksum) is adopted. Options and Fills The variable portion of the header is added to increase the functionality of the IP datagram, such as support for troubleshooting, Measurement and security, options ranging from 1 to 40 bytes, depending on the selected item (option is 4 byte integer multiple, otherwise 0 padding); However, t
