To develop a complete Python Web application, follow these steps: 1. Choose the appropriate framework, such as Django or Flask. 2. Integrate databases and use ORMs such as SQLAlchemy. 3. Design the front-end and use Vue or React. 4. Perform the test, use pytest or unittest. 5. Deploy applications, use Docker and platforms such as Heroku or AWS. Through these steps, powerful and efficient web applications can be built.

To get a specific column value for a row from a layui table, you can do it by following the steps: Listen to the row or tool event of the table, using the table.on method. In the event handler function, the data of the current row is obtained through the data attribute of the event object. Extract the value of a specific column from the data object according to the field attribute of the column. For example, listen for row events and get the value of the 'username' column: table.on('row(test)',function(obj){vardata=obj.data;variusername=data.username;console.log('The username value of the current row is

The way to add a custom button column in a Layui table is to specify the template ID through the toolbar property and handle button click behavior through event listening. The specific steps include: 1. Use the toolbar attribute to specify the template ID in the table configuration; 2. Write the template content and define the buttons and their events; 3. Use the event listening mechanism to handle the button click behavior. The advantage of this method is its high flexibility, but it should be noted that too many buttons may affect performance.

Implementing the column sorting function in Layui tables can be achieved through the following steps: 1. Enable the sorting function in the table configuration, 2. Customize the sorting logic. Layui tables support client and server-side sorting. Users can sort data in ascending or descending order by clicking on the table header to improve the readability and usability of the data.

Dynamically adding radio box options in Layui can be achieved through the following steps: 1. Get the form element, 2. Create a new option, 3. Insert a new option and re-render with form.render('radio'). Through these steps, forms can be dynamically updated based on user interaction or backend data, improving application flexibility and user experience.

The core of the front-end routing system is to map URLs to components. VueRouter and ReactRouter realize refresh-free page switching by listening for URL changes and loading corresponding components. The configuration methods include: 1. Nested routing, allowing the nested child components in the parent component; 2. Dynamic routing, loading different components according to URL parameters; 3. Route guard, performing logic such as permission checks before and after route switching.

The core differences between Vue.js and React in component development are: 1) Vue.js uses template syntax and option API, while React uses JSX and functional components; 2) Vue.js uses responsive systems, React uses immutable data and virtual DOM; 3) Vue.js provides multiple life cycle hooks, while React uses more useEffect hooks.
