List filtering is commonly used and practical in Python. The main methods include: 1. Use list comprehension to perform basic filtering, which is suitable for simple conditional judgments, such as retaining even numbers, filtering empty values, limiting string lengths, or filtering specific types; 2. Use filter() function to combine lambda expressions to be suitable for reusing complex logic, but with slightly poor readability; 3. When processing nested structures, you can extract the judgment logic as an independent function to improve maintainability and scalability. The selection method should be determined based on the specific scenario to ensure clear and efficient code.

The key to implementing search filtering functions in Vue projects is to use computed attributes for responsive data processing. 1. First prepare the list data and input boxes, use v-model to bind search keywords, and render the filtered list through v-for; 2. Use the computed attribute to define filteredList, and use searchQuery to perform case-insensitive inclusion matching of items, so as to achieve automatic update without modifying the original data; 3. You can add search results prompts and anti-shake mechanisms to improve your experience; 4. If you need multi-field filtering, you can expand the matching logic inside the filter or split multiple input boxes to combine the query.
