python创建多个logging日志文件_python 多个logger

为每一个计算过程创建一个单独的日志文件，并写入对应的结果，同时保留控制台输出的功能，控制台输出与日志文件记录可以分开单独控制。

import os
import shutil
import logging
 
def creat_logger(log_path,logging_name,suf_name):
    
    if not os.path.exists(log_path):
        os.makedirs(log_path)
    log_full_path = log_path + logging_name + suf_name
    
    logger = logging.getLogger(logging_name)
    logger.setLevel(level=logging.DEBUG)
    
    
    handler = logging.FileHandler(log_full_path, encoding='UTF-8',mode = 'w')
    handler.setLevel(logging.INFO)
    formatter = logging.Formatter('%(asctime)s - %(name)s - %(levelname)s - %(message)s')
    handler.setFormatter(formatter)
    
    
    console = logging.StreamHandler()
    console.setLevel(logging.DEBUG)
    logger.addHandler(handler)
    logger.addHandler(console)
    return logger
 
if __name__ =='__main__':
    if os.path.exist('./log/'):
        shutil.rmtree('./log/')
    for i in range(5):
        for j in range(4):
            
            log_trace = creat_logger('./log/i_loop'+str(i)+'/','j_loop'+str(j),'.txt')
            
            log_trace.debug('DEBUG: iloop = %d , jloop = %d',i,j)
            log_trace.info('INFO: iloop = %d , jloop = %d',i,j)
            
            for handler in list(log_trace.handlers):
                log_trace.removeHandler(handler)
