python日志记录打印到文件但没有控制台[重复]

Question

logger configuration to log to file and print to stdout 不适合我，所以：

我想在控制台中的 prog_log.txt 和中打印日志记录详细信息，我有：

# Debug Settings
Import logging
#logging.disable()  #when program ready, un-indent this line to remove all logging messages
logging.basicConfig(level=logging.DEBUG,
                    filename = 'prog_log.txt',
                    format='%(asctime)s - %(levelname)s - %(message)s',
                    filemode = 'w')
logging.debug('Start of Program')

上面确实将日志记录详细信息打印到 prog_log.txt 文件中但控制台上没有任何内容..

In [3]: runfile('/Volumes/GoogleDrive/Mon Drive/MAC_test.py', wdir='/Volumes/GoogleDrive/Mon Drive/')
...nothing...

欢迎任何帮助

logger configuration to log to file and print to stdout 的副本

您需要添加和处理程序以将日志设置为 StreamHandler ：

logging.basicConfig(level=logging.DEBUG,
                    filename = 'prog_log.txt',
                    format='%(asctime)s - %(levelname)s - %(message)s',
                    filemode = 'w')
logger.addHandler(logging.StreamHandler())

或

logging.basicConfig(
    level=logging.DEBUG,
    format='%(asctime)s - %(levelname)s - %(message)s',
    filemode = 'w',
    handlers=[
        logging.FileHandler('prog_log.txt'),
        logging.StreamHandler()
    ]
)
