Logging

日志处理

When calling a logger by for example calling logger.infog(...) or logger.debug(...) etc.. always use lazy string formatting when interpolating variables for performance.
Bad example. Must avoid:
python
logging.error(f"Python version: {sys.version}")
Good example, use Lazy formatting
python
logging.error("Python version: %s", sys.version)
当调用日志记录器（例如调用logger.info(...)或logger.debug(...)等方法）时，在插入变量以提升性能时，务必使用延迟字符串格式化。
错误示例，必须避免：
python
logging.error(f"Python version: {sys.version}")
正确示例，使用延迟格式化：
python
logging.error("Python version: %s", sys.version)
