In Laravel, a route is the entry point for the application that defines how HTTP requests are processed and point to specific code. The routing file is located in the routes/ directory, mainly including: routes/web.php for web page requests (including sessions and CSRF protection), routes/api.php for API interface (stateless, using API middleware), routes/console.php for Artisan command, routes/channels.php for broadcast events. The basic routing syntax is defined by closures, such as Route::get('/hello',function(){return'Hell

Tuples are immutable sequence types that are suitable for storing fixed data. 1. Create tuples with brackets and commas to separate elements, and a single element needs to be added to avoid ambiguity; 2. The tuple is immutable and cannot modify elements, but the entire variable can be reassigned; 3. Support unpacking operations, and the tuple value can be assigned to multiple variables, and partial unpacking is achieved with the * operator; 4. Due to immutability, tuples can be used as dictionary keys, but lists cannot; 5. Support connection, repetition and traversal operations, which are often used for function returns multiple values, and are lightweight and efficient. Pay attention to the details of commas and immutability when using.

itertools.combinations is used to generate all non-repetitive combinations (order irrelevant) that selects a specified number of elements from the iterable object. Its usage includes: 1. Select 2 element combinations from the list, such as ('A','B'), ('A','C'), etc., to avoid repeated order; 2. Take 3 character combinations of strings, such as "abc" and "abd", which are suitable for subsequence generation; 3. Find the combinations where the sum of two numbers is equal to the target value, such as 1 5=6, simplify the double loop logic; the difference between combinations and arrangement lies in whether the order is important, combinations regard AB and BA as the same, while permutations are regarded as different;

The button hover color gradient is set to smoothly change in 0.3 seconds through transition setting background-color and color, and can achieve natural transition with ease function, and add box-shadow to enhance three-dimensionality; 2. The image enlargement effect uses transform:scale(1.1) and transition:transform0.4sease to achieve hover zoom to avoid layout re-arrangement. It is recommended that the parent container set overflow:hidden to prevent overflow; 3. The underscore sliding effect uses pseudo-element::after to create an underscore with an initial width of 0 and center, and the transition is simultaneously transitioned during hover.

Create a ZIP file and use the zipfile module in Python. 1. Basic usage: Create a ZIP file through zipfile.ZipFile('example.zip','w'), and add individual files such as file1.txt and file2.txt using the write() method. 2. Advanced usage: Use os.walk() to traverse the directory, combine os.path.relpath() to maintain the relative path structure, and compress the entire folder into a ZIP file. 3. Compression options: 'w' mode will overwrite the original file, ZIP_DEFLATED enables compression, arcname avoids saving absolute paths. 4. Tips: Skip it.D

Go does not have built-in collection types, but it can achieve efficient and type-safe collections through map[T]struct{}. 1. Use map[T]struct{} to implement type-safe collections: define a generic Set structure and provide Add, Remove, Contains, Size and Values methods; 2. struct{} as a value type is more efficient than bool because of its zero memory overhead; 3. You can directly use map[string]struct{} to implement simple collection operations; 4. If concurrency security is required, you can combine sync.RWMutex encapsulation; 5. Note that only comparable types can be used as keys, and native map operations are not thread-safe. This

To install macOS from DMG files, you need to prepare to boot the USB drive and write to the mirror. 1. Prepare at least 16GB USB drive and format it as "MacOS extension (log)"; 2. Use the terminal commands hdiutilverify, hdiutilmount and asrrestore to write DMG to the USB drive; 3. If you only need to view or extract content, you can directly mount the DMG file and drag and drop the application; 4. In case of write protection or permission problems, you can try to repair the disk, re-download the file, or convert the format to IMG before operating. The entire process requires ensuring that the DMG file is legal and complete before the system installation can be successfully completed.

There are three common methods to find the intersection of two lists in Python: ① Use set to quickly get the intersection, which is suitable for situations where there is no need to retain order and duplicates; ② Use list comprehension to retain order and convert one of the lists into a collection to improve efficiency; ③ Use collections.Counter to process intersections containing duplicate elements, so that the number of repetitions can be retained. Different methods are suitable for different scenarios, solving the requirements of efficiency, sequence and duplicate items respectively.

The answer is to implement WorkerPool mode using channel and goroutine to control the number of concurrent and efficiently process batch tasks. 1. Define the task job and result Result structure; 2. Create buffered task channel and result channel; 3. Start a fixed number of workergoroutines, each worker reads the task from the jobschannel and writes the resultschannel, and calls wg.Done() after completion; 4. The main goroutine sends all tasks and closes the jobschannel; 5. Use sync.WaitGroup to wait for all works
