After following, you can keep track of his dynamic information in a timely manner
Using parameterized queries is the core method to prevent SQL injection in Python, and it is necessary to avoid direct splicing of user input. 1. Always use parameterized queries supported by database drivers, such as placeholder mechanisms in sqlite3, psycopg2, and mysql-connector-python; 2. It is prohibited to construct SQL statements through string splicing or formatting (such as f-string, .format()); 3. Priority is given to using ORM libraries such as SQLAlchemy or DjangoORM, which use parameterized queries by default; 4. Verification and filtering of user input as supplementary defense, including type, length and whitelist verification; 5. When handling dynamic table names or column names, white must be used.

Using Array.isArray() is the most reliable way to determine whether a variable is an array, because it performs consistently in all environments and correctly recognizes the array; typeof is not available because it returns "object" to the array; instanceofArray may fail in cross-context scenarios; Object.prototype.toString.call() is feasible but too cumbersome; therefore, Array.isArray() should be preferred.

To import fonts, use @font-face or GoogleFonts. 1. When using @font-face, define the font-family, src paths and formats. It is recommended to use .woff2 and set font-display:swap to ensure that the text is visible; 2. When using GoogleFonts, you can add link tags to HTML or use @import to introduce font links on the top of CSS. Note that @import must be placed at the top of the CSS file. It is recommended to use .woff2 format first. Hosting fonts by yourself can improve performance and privacy protection, while CDN services are more convenient, but too much font weight should be avoided to avoid affecting speed.

sys.argv is used to parse Python command line parameters, where sys.argv[0] is the script name and subsequent elements are passed parameters; 1. Use sys.argv[1] to obtain the first parameter, and you need to check the length first to avoid index errors; 2.

This C TCP example shows the basic communication process between the server and the client: 1. The server creates socket, binds ports, listens, accepts connections, reads data and sends responses; 2. The client creates sockets, connects to the server, sends messages, and receives reply; 3. Closes the connection after the communication between the two parties is completed; the code is suitable for Linux/macOS, uses POSIXsocketAPI, and needs to be compiled through g. After running, the server listens to port 8080, the client connects and exchanges messages, and exits normally after the program is executed.

First try to replace the USB interface or connect to another computer to troubleshoot connection problems; 2. If not displayed, enter disk management to check whether the disk letter is missing, and if so, assign the drive letters; 3. Update or reinstall the USB driver to resolve the driver exception; 4. Turn off USB selective pause settings and confirm that the USB port in the BIOS is enabled; 5. Use the diskpart command to check whether the file system is corrupt, and format it after backup if necessary, and scan for viruses; 6. If it cannot be recognized on multiple devices, it may be that the USB disk hardware is damaged and needs professional recovery. The problem usually comes from connection, driver or settings, rather than a USB flash drive itself. Following the steps to solve most cases.
