This sine wave animation example shows the basic process of creating animations using FuncAnimation in Matplotlib, 1. Create canvas and axis and set ranges; 2. Prepare fixed x-axis data and dynamic y-axis data to initialize empty lines; 3. Define the init function to set the animation start state; 4. Define the update function to update the y value in each frame to achieve phase movement; 5. Use FuncAnimation binding parameters to create animation objects, specify frame count, interval and optimization options; 6. Add title, label and grid to display animation; finally present the complete animation through plt.show(), and the entire process completely realizes data preparation, update logic and animation display, suitable for beginners to master M

To effectively handle race conditions in Go, you must first use the built-in race detector and enable the -race flag in testing; 1. Use gorun-race or getest-race to detect potential races in development and CI; 2. Protect shared data through sync.Mutex or sync.RWMutex to ensure the atomicity of write operations; 3. Use channels instead of shared memory to share data through communication between goroutines; 4. Use sync/atomic packets for simple operations such as counters to achieve lock-free concurrency security; 5. Avoid goroutine error capture of loop variables, and the values should be isolated by passing parameters or local variables. Always run race detection regularly to protect or avoid shared state

threading.Event is used for signal transmission between threads. 1. event.set() sets the flag to True to wake all waiting threads; 2. event.clear() sets the flag to False to block wait(); 3. event.wait() blocks threads until the flag is True; in the example, three worker threads call wait() to wait, and the main thread calls set() to wake them up to perform tasks uniformly. It can also be used for background threads to check the stop signal by is_set() to achieve elegant exit, supporting timeout waiting and state reset, suitable for scenarios such as startup synchronization, task coordination and elegant closing.

To remove DOM elements, the easiest way is to use the remove() method: 1. Use the remove() method to directly delete elements. The code is concise and suitable for modern browsers, such as document.getElementById('myElement')?.remove(); 2. Use the removeChild() method to delete children through the parent node, which has better compatibility and can return the deleted node for reinsertion, such as parent.removeChild(child). It is recommended to use remove() first. If you need to be compatible with old browsers or must operate through the parent node, use removeChild().

Check and display the file extension to ensure that it is valid formats such as .xlsx or .xls; 2. Open the file with Notepad to view the content and determine whether it is CSV, HTML or garbled code; 3. If it is CSV or text format, open it through Excel's "Data" → "Import from Text/CSV" function; 4. Try to use Excel's "Open and Fix" function to restore abnormal files; 5. Re-download or export files from the source system to avoid incomplete transmission; 6. Test opening on other devices to eliminate local environment problems; as long as you clarify the real format of the file and take corresponding actions, you can solve the problem that Excel cannot open.
