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.

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.

Methods to optimize the performance of large lists and complex components in Vue include: 1. Use the v-once directive to process static content to reduce unnecessary updates; 2. implement virtual scrolling and render only the content of the visual area, such as using the vue-virtual-scroller library; 3. Cache components through keep-alive or v-once to avoid duplicate mounts; 4. Use computed properties and listeners to optimize responsive logic to reduce the re-rendering range; 5. Follow best practices, such as using unique keys in v-for, avoiding inline functions in templates, and using performance analysis tools to locate bottlenecks. These strategies can effectively improve application fluency.

To use v-model to implement two-way binding of custom components in Vue, you must first understand its working mechanism. For custom components, you need: 1. Receive a prop named modelValue; 2. Trigger an event named update:modelValue. By default, it will be parsed to, so the component needs to use:value="modelValue" and $emit('update:modelValue') to synchronize the data. In addition, the prop and event names can be customized via model:{prop:'checked',event:'change'}, which are suitable for different types of components such as switches
