PydbliteWebpy: Python's class library introduction used to quickly build database applications

PydBlite is a lightweight Python database, which provides a simple and powerful way to build a database application.Web.py is a simple but powerful web framework that can be used to build a web application.Combined with Pydblite and Web.py, we can quickly build a database application. Before starting, we need to install PydBlite and Web.py Library.You can use the following command for installation: pip install PyDBLite pip install web.py First, we need to create a database and a table to store data.The following is an example: python from DB import DB db = DB() db.create('students', ['name', 'age', 'grade']) Next, we can use web.py to create a simple web application and integrate pydblite with it.The following is a simple example: python import web from DB import DB # Create database connection db = DB() # 创 创 db.create('students', ['name', 'age', 'grade']) # Define the URL routing urls = ( '/', 'index', '/add', 'add_student', ) # Define the homepage processor class index: def GET(self): # Get all student information from the database students = db['students'].rows return students # Define the additional student processor class add_student: def POST(self): data = web.input() # Add student information to the database db['students'].insert(name=data.name, age=data.age, grade=data.grade) Return 'Student information is added successfully!' # if __name__ == "__main__": app = web.application(urls, globals()) app.run() In the above code, we first import Web and DB libraries.We then created a database connection and a form called "Students".Next, we define two URL routing: "/" for homepage and "/add" to add student information.In the homepage processor, we obtain all student information from the database and return.In the addition of student processors, we obtain student information from the request and add it to the database. Finally, we use web.application () to create an application object and start the application by calling the app.run () method. To run this application, you can run the above code.Then, open the browser and visit "http: // localhost: 8080" to view the homepage.You can also visit "http: // localhost: 8080/add" and add student information through the form. This article introduces how to quickly build a simple database application with pydblite and web.py.By using these two libraries, we can easily create and manage databases, and build a powerful web application.
