The introduction and basic use of Python Saws library

SAWS (Simple API for Web Scraping) is a Python class library that is used to grab data from the webpage.It provides a simple and easy -to -use interface, allowing users to easily extract the required information from the webpage through the Python script and use it for various purposes, such as data analysis, crawlers, etc. The basic use of the SAWS class library is very simple. Users only need to follow the steps below to execute: 1. Install the SAWS class library: First of all, you need to install the SAWS library on the local computer. You can perform the following commands through the PIP tool: python pip install saws 2. Import SAWS class library: Import SAWS class libraries in the Python script to use the functions provided by SAWS in the script. python import saws 3.
