HomeBackend DevelopmentPython TutorialPython中logging模块的用法实例

本文实例讲述了logging模块的用法实例,分享给大家供大家参考。具体方法如下:

import logging 
import os 
 
log = logging.getLogger() 
formatter = logging.Formatter('[%(asctime)s] [%(name)s] %(levelname)s: %(message)s') 
 
 
stream_handler = logging.StreamHandler() 
file_handler = logging.FileHandler(os.path.join("c:\\", "analysis.log")) 
 
 
file_handler.setFormatter(formatter) 
stream_handler.setFormatter(formatter) 
 
 
log.addHandler(file_handler) 
log.addHandler(stream_handler) 
log.setLevel(logging.DEBUG) 
 
 
log.warn("a warning %s " % "c:\\") 

程序运行结果如下:

[2014-09-29 10:23:58,905] [root] WARNING: a warning c:\

In the fields of finance, scientific research, medical care and AI, it is crucial to efficiently store and process numerical data. 1) In finance, using memory mapped files and NumPy libraries can significantly improve data processing speed. 2) In the field of scientific research, HDF5 files are optimized for data storage and retrieval. 3) In medical care, database optimization technologies such as indexing and partitioning improve data query performance. 4) In AI, data sharding and distributed training accelerate model training. System performance and scalability can be significantly improved by choosing the right tools and technologies and weighing trade-offs between storage and processing speeds.

In addition to the shebang line, there are many ways to specify a Python interpreter: 1. Use python commands directly from the command line; 2. Use batch files or shell scripts; 3. Use build tools such as Make or CMake; 4. Use task runners such as Invoke. Each method has its advantages and disadvantages, and it is important to choose the method that suits the needs of the project.
