In Python, you can use the built-in logging module to print log files. Here is a simple example code:

import logging

# 设置日志级别
logging.basicConfig(filename='example.log', level=logging.DEBUG)

# 打印日志信息
logging.debug('This is a debug message')
logging.info('This is an info message')
logging.warning('This is a warning message')
logging.error('This is an error message')
logging.critical('This is a critical message')

In the example above, we set the log file name and log level by calling logging.basicConfig(). Then, we use methods like logging.debug(), logging.info(), logging.warning(), logging.error(), and logging.critical() to print log information at different levels to the file.

After running this code, a log file named “example.log” will be generated in the current directory, which will record the corresponding levels of log information in the file.
